These were early hybrid desktop drives when people did not have sata power cables inside their desktops, so they gave you a choice of power connections, Do Not connect both of them at the same time. It will smoke the drive, don’t ask how I know this..

The Molex connector was discontinued on Sata drives for obvious reasons. They started shipping sata to molex adapters with sata drives instead.

See this PDF. That is a very interesting hard drive, to have both a SATA power connector and a Molex style connector that PATA hard drives have.

Try one or try the other. In this case i’d suggest perhaps not to try both (If you find that each don’t work alone, then you’re better off taking your drive to a data recovery place).

You could try powering it with the PATA power and the SATA data. Or with the SATA power and SATA data.

you make sure it’s got power and that the data is connected.

This essay will show you some knowledge about internal and external hard drive power cable as well as HDD interfaces. Read more related information on MiniTool partition resizer official website.

To make it simple, they are lines to connect hard disks and motherboards together. The types of power cable for hard drives are determined by the hard disk drive interface.

Yet, there are still hard disks that have the same interface for both power and data connection. That is, you only need one connecting cable to connect the drive with the motherboard for both data and power transmission.

How to connect to manage this kind of hard drive on Windows PC. Today’s article will discuss these questions in detail.

And, an extra cable is needed for power supply. SMD.

SMD interface was the popular standard interface for minicomputers in the 1970s and 1980s. ST-506/ST-412/ST-412RLL.

They were standard interfaces for most small HDDs in the 1980s and early 1990s. They used MFM (Modified Frequency Modulation) or latter RLL (Run Length Limited) for the data encoding method.

Enhance Small Disk Interface is also a type of bit serial data interface first introduced by Maxtor in the late 1980s and sponsored by ANSI. ESDI is an industry-standard interface similar to ST412 that supporting higher data rate flow.

How to upgrade IDE to SATA HDD or SSD. There is a step-by-step tutorial to help you.

CTL-I. Controller Interface is a word-serial interface and 8-bit disk interface introduced by IBM for its mainframe hard drives beginning with the 3333 in 1972.

Small Computer System Interface is a kind of word serial interface sponsored by ANSI and introduced in the middle 1980s. it is the standard interface explicitly deployed to minimize system integration efforts for most enterprise, server, and workstation HDDs in the 20th century.

SCSI was originally named SASI (Shugart Associates System Interface, introduced by Shugart Associates circa 1978) and was replaced by SAS. PATA.

It replaced ST-412, ST-506, and ESDI, and was originally IDE and then was standardized under the name AT Attachment (ATA). AT Attachment reflects the integration of the controller with the hard drive.

The integration of the controller and hard drive standardizes the host/controller interface, reduces the programming complexity, as well as reduces system cost and complexity. PATA is a standard HDD interface on all except for enterprise HDDs until superseded by SATA.

This post explains SATA meaning to you. Modern bit serial interfaces connect a hard disk drive to a host bus interface adapter, which is integrated into the southbridge on the motherboard in most computers, with a single control/data cable.

DECs Standard Disk Interface is an early example of a modern bit-serial interface type. FC.

It is a serial protocol. Usually, the Fibre Channel Arbitrated Loop (FC-AL) connection topology is used in hard disks.

Serial AT Attachment data cable has one data pair for differential transmission of data to the drive, and one pair for differential receiving from the drive. that needs the data to be transmitted serially.

SATA succeeded PATA. It is sponsored by ANSI and introduced in 2003.

Serial Attached SCSI is the new generation of the serial communication protocols for devices that are designed for much higher data transmission speed. It is the successor to SCSI sponsored by ANSI and introduced in 2004.

SAS makes use of a mechanically identical power and data connector for standard 3.5” SATA1 and SATA2 hard drives. SAS is compatible with SATA, and many server-oriented SAS RAID controllers are also able to address SATA disks.

What do you know about SATA speed. What are the differences between SATA 1, SATA 2 and SATA 3.

Sometimes, you can’t directly connect an HDD power cable with a hard disk. Then, you can make use of a SATA hard drive power cable adapter, a hard drive power extension cable, an SSD hard drive power cable splitter (Y shape), etc.

Installing an internal hard drive is one of the more straightforward upgrades out there—and is often a better option than using external drives that may be dropped or misplaced.

Still, there are a few things you should know to make installation as smooth as possible.

If you’ve opted for a solid-state drive, be sure to check out our companion guides explaining how to install an SSD in a desktop and a laptop. SSDs tend to offer much faster speeds than hard drives, but hard drives offer significantly more capacity at lower prices.

All three spin at 7,200 revolutions per minute (RPM), the fastest speed available in consumer hard drives. Now let’s get this hard drive installed in your computer.

Placement and orientation of the cages or bays will vary from case to case. The most common location is at the lower front, near the intake fans and away from other components.

Screws are the best way to secure your hard drive into your case’s drive cage. Magnet-tipped screw drivers can help keep you from dropping screws in difficult-to-reach places.

In enthusiast-class cases, it’s becoming more common to see the drive’s connectors facing the right side, making it easier to route and hide cables behind the motherboard tray. Some enthusiast-class also cases give users the ability to remove drive cages or to mount them in different positions to optimize air flow and simplify cable management.

Securing the drive to a cage usually requires four screws on the sides or bottom of the drive. Many cases—especially enthusiast cases—use tool-less trays that hold the drives with simple pins and clips.

However, these brackets are often less secure than traditional screws. Using screws is the more robust mounting method, but tool-less trays are fine for systems that won’t be moved around much.

Seven of the 10 screw holes are circled in red, while SATA power and data connections are circled in blue and green, respectively. Drives last longer when they stay nice and cool.

Positioning the drives directly in front of an intake fan also helps. Once the drive is mounted, connecting it to your system is quick and easy.

SATA uses simple cables that are keyed to fit on the drive and motherboard connector one way. Connect one end of the SATA cable to the drive, and the other end to an available SATA port on your motherboard, and you’re halfway there.

You may find the SATA cables included with your new drive or motherboard feature different connectors: straight ends or right-angle (L-shaped). Some may have metal retention clips, while others do not.

I like to use SATA cables with right-angle connectors on the drive side, provided there is adequate clearance between any drives in the system. Using right-angle connectors on the motherboard side will will result in blocked ports, because the connector may overlap adjacent ports.

Most SATA 3 (6-gigabit)-compliant cables will usually come with the clips. The SATA power cable connection looks similar to the data cable, but is longer.

When you’re done connecting the SATA cable, you’ll have to connect the drive to your power supply unit (PSU). The SATA power cable from your PSU, like the SATA data cable, is keyed to fit onto the drive one-way.

Once you’ve mounted and connected the drive, power up your system and enter the BIOS/UEFI. You can usually access the BIOS/UEFI by pressing the DEL or F2 keys right after powering up the system.

In the BIOS, go to the standard System Settings menu or the Integrated Peripherals > SATA menu to see all of the drives installed in the system. If all of your drive controllers are enabled and the drive is properly connected (and functional), it should be listed in the BIOS.

If the drive isn’t listed, shut down your PC. Double-check all of the connections, boot into the BIOS and check again.

The UEFI BIOS will show all hard drives that are connected correctly and detected by the system. BIOS and UEFI interfaces can differ based on the motherboard make and model, so check your motherboard manual or manufacturer website for details.

In Windows 10, right-click the Windows button on your desktop and select Device Manager. Check for the drive in the Disk Drives section.

When you boot into Windows after installing the drive, you may see the New Hardware Found wizard pop up if the drive is detected. The last thing you need to do is partition and format the drive.

If you split the drive up into multiple partitions, you should see several drives appear in File Explorer, each with its own drive letter and label.

Hard drives can be thought of as a series of precise mechanical components that work together to store digital information with magnetic charges. These charges are stored on disks, referred to as platters, and each platter has a set of heads that flies across its surface to read and write data.

Of course, hard drives are not simple devices, and this definition leaves out quite a bit of important information.

Hard drives gained popularity because they offer relatively high maximum storage capacities at a low price as compared to NAND flash and other storage technologies.

This means that you have a terabyte of free space from the moment you plug the drive into your computer – but not in the way you might think.

It is very important to note that since the beginning of the consumer hard drive industry, manufacturers have defined a kilobyte as 1,000 bytes (called the metric prefix) while software developers have defined a kilobyte as 1,024 bytes (the binary prefix). This is an important designation, because it directly affects the usable capacity of a hard drive.

A 2 terabyte hard drive will only have 1.82 terabytes of usable data. The larger the storage device, the bigger the disparity between the reported capacity and the usable capacity.

When you purchase a drive, make sure that the device will have enough space for your software, documents, videos and other files while still leaving about 30 percent of the space free to ensure optimal operational efficiency.

Many of these numbers can be useful when diagnosing hard drive performance issues.

Hard drives communicate with computers through a printed circuit board (PCB) outfitted with an appropriate interface, which is sometimes referred to as a bus type. Each interface type has different characteristics, especially in relation to data transfer rates.

The most common hard drive interface types include:. Serial Advanced Technology Attachment or SATA is by far the most common interface for newer hard drives.

SATA also has relatively small transfer and power cables as compared to PATA. Also known as EIDE, IDE and by several other acronyms, Parallel Advanced Technology Attachment (PATA) was commonly used through the early 2000s.

PATA’s maximum data transfer speed was 133 megabytes per second. While PATA drives are still manufactured, SATA is a superior technology and a better option for most computers.

SAS uses SATA-like connections, and many computers with SAS capabilities can also read and write data from SATA drives. SAS offers transfer speeds of up to 12 gigabytes per second.

Introduced after SCSI, Fibre Channel (FC) is usually used for storage area networks (SAN). It offers fast transfer speeds, but contrary to the name, it does not use fibre optics to transfer data at the disk level.

External hard drives typically use one of the interfaces listed above, but add an external USB or Firewire port that allows them to connect to computers easily. These ports include USB, eSATA, Thunderbolt and IEEE 1394 (FireWire).

Desktop hard drives are 3.5-inches in length, while laptop hard drives measure at 2.5-inches (they are also much slimmer on average). While laptop hard drives can be used in desktop computers with special mounting hardware, they are relatively expensive as compared to 3.5-inch drives, so there are few reasons to mount a 2.5-inch drive in a desktop computer except in special circumstances.

Server hard drives usually have the same 3.5-inch form factor, but have additional features (such as SAS connections) that make them ideal for constant operation in demanding applications. They are typically more expensive than standard desktop hard drives.

SSD technology offers several performance advantages over traditional hard drives, including faster read/write speeds and resistance to damage from physical shocks and vibrations.

Unlike standard hard drives, they do not store magnetic charges, and they do not have mechanical components. However, they cannot offer perfect protection against data loss – the NAND flash memory used by solid-state drives can wear down over time, which is why most newer drives employ wear-leveling technologies to extend operating life.

The other major disadvantage of SSD is that it is expensive as compared to traditional hard drives, and storage capacities are much lower. Many computer users choose to use SSD for their operating systems and software and HDD for long-term data storage, which can provide the advantages of both technologies.

These drives only spin their platters to access data when absolutely necessary, which should theoretically extend the operating life of the drive while reducing energy consumption and improving data access speeds.

This usually requires a special piece of hardware called a controller, but software can act as a controller for smaller multi-drive configurations. Some external hard drives with large capacities actually consist of several hard drives linked together with a hardware controller.

Most computers that use multiple hard drives use a configuration called RAID (Redundant Array of Inexpensive/Independent Disks). There are several RAID levels, which offer different benefits in terms of performance and redundancy (the term “redundancy” refers to the array’s ability to withstand hard drive failures without losing data).

Some of the most popular types of RAID are listed below.

Data is written to all of the drives in the array at the same time. In a two-drive RAID 1, if either drive fails, the other drive has the same set of data.

RAID 0 is not technically a RAID, since it does not provide any redundancy. Data is striped across the member disks, so each drive has an equal amount of the information.

However, because there is no redundancy, a single hard drive failure will result in data loss. This is the most common RAID configuration used for web servers and larger storage systems.

a RAID 5 can sustain a hard drive failure without losing any data. A RAID 5 requires at least three hard drives.

Similar to RAID 5, but with another parity block. This allows for more redundancy.

The added parity block may mean reduced performance, but RAID 6 can be just as fast as RAID 5 depending on its implementation. This term refers to RAID configurations that combine two implementation technologies for improved performance and redundancy.

This allows for fast write speeds with some fault tolerance. Other common nested RAID levels include RAID 50 (combines RAID 5 and RAID 0) and RAID 01 (the opposite of a RAID 10, a mirror of striped drives).

Businesses rarely use JBOD, since it does not offer performance improvements or redundancy, but it can offer a simple way to store large amounts of data in some applications. Some manufacturers have their own proprietary RAID configurations, which ma.

The hard drive not showing up issue can be caused by many different things. The most common issues are ones with bad sectors, failed heads if the drive was dropped, or issues with partition corruption.

This particular Seagate ST2000DM001 2TB Desktop Drive came from a shop that offers some data recovery services, but mainly focuses on computer repair. Their client had reported the drive no longer would be recognized by any computer, and the shop verified this was the case by attaching it to their test machines.

The shop that looked at the drive initially recommended the customer contact us regarding data recovery as they had important files on the drive that had not been backed up. In the past, this shop had recommended one of the larger data recovery companies that reportedly quoted over $1000 for every drive that was ever sent to them.

The client called to discuss their Seagate hard drive not showing up and we set up an appointment for dropoff. Once I received the drive, I completed a visual inspection and immediately saw the issue.

I had a donor Printed Circuit Board (PCB) in stock for this exact model so I was able to swap out the PCB and swap over the ROM chip right away. Once the PCB and ROM chip swap was complete, I connected the drive to the PC-3000 and completed all the standard procedures to prepare the drive for imaging.

Since the drive was now spinning up and reading properly, I was confident the issue had been addressed, but you should always complete the imaging process before moving on to the data transfer stage. The imaging process was completed with very few bad sectors being found.

There is usually a feature in the firmware of a drive that recognizes failing sectors and marks them to not be used in the future. When I turn off those features while imaging a drive, I will hit those bad sectors and sometimes not be able to recover them.

Once all the sectors were imaged I used a few of my favorite data recovery programs to scan the sectors and bring back all the data with full folder structure and file names. I moved all the recovered data onto the customer’s new drive, and they were very pleased with the results.

I don’t see a lot of these power-related issues, but every once in a while I will get a drive that has PCB damage as the main issue. If you have a drive that needs to be recovered, please fill out my data recovery quote form and I will get back to you on what will likely be needed to complete the recovery right away.

Hard drives have one central use – the storage of data for later retrieval. They store three kinds of data:

Apple has now standardised its entire range of Mac computers onto SSD hard drives. These range in capacity from 256 GB on its MacBook range up to the colossal 8 TB SSD drive available for the Mac Pro, which is aimed at professional content creators and editors.

Some offer a closely related variant, USB 4, which will work with Thunderbolt 3 devices, but which is also backwards compatible with USB 3.2 and 2.0. Therefore, it is important to make sure that external hard drives intended for use with a Mac will work with Thunderbolt 3 and USB 4 ports.

You are only limited by the ports available on your device. However, the highest quality desktop drives are often recommended for quality and longevity.

The purpose of this guide is to learn about enable or disable Linux HDD sleep. cover the steps necessary to change a hard drive’s sleep/standby mode timer on Linux.

Depending on your system’s usage and environment, the time your hard drive is in an idle state may vary. Every time a hard drive has nothing to do, it waits a certain period of time, and then it enters sleep mode.

By reducing a timer before the hard drive goes to sleep mode, we can save some power. Adjusting a hard drive’s standby timer can be done from the GUI or command line.

In this tutorial you will learn:.

But if not, you can use the appropriate command below to install the program with your system’s package manager. To install hdparm on Ubuntu, Debian, and Linux Mint:

In this Linux HDD sleep guide, we learned how to enable and disable standby mode on a hard drive in Linux. We also saw how to adjust the amount of time it takes before a hard drive enters standby.

Ready to upgrade your hard drive and found you’re dealing with a SATA connector. SATA drives are easy to set up, support hot swapping, and the interface is reasonably fast.

Serial ATA (SATA) connectors remain a common interface between the drive and the motherboard. The image above shows a 2.5″ SATA hard drive from Fujitsu with the data port on the left and the power port on the right.

You’ll find SATA interfaces in both hard drisk drives (HDDs) and solid state drives (SSDs). SATA drives were introduced to replace IDE and Enhanced IDE (Parallel ATA) drives.

As well as a specific port, SATA offers substantial improvements in data transfer rates. The original SATA specification transfers data at speeds up to 150 MB/s.

While the latest SATA iteration isn’t in use for consumer drives, the technology does eventually filter into those products. Solid State Drives sales have rapidly increased throughout the past few years, from around 39 million units in 2012 to an estimated 360 million in 2021.

Wondering which one is right for you. And do you need an SSD at all.

Consider your use case: If you need a large amount of storage at an affordable price and don’t plan on using it as an everyday drive running your operating system, i.e. it doesn’t need to be ultra-fast, then a regular HDD drive is the right choice.

If you’re looking for the fastest possible drive and neither price nor storage capacity are an issue, consider an SSD and check whether your computer has a PCIe slot. Note that SATA SSDs are only available in the smaller 2.5″ form factor.

Before installing a new hard drive, take the following precautions to prevent damaging your hardware. Before you open the case and begin fiddling with the hardware, shut your system down.

You’ll find the switch at the back of your case. Once turned off, hold the power button down for a few seconds to discharge any remaining power.

An electrostatic shock comes from a static energy build-up in your body. As you touch the metallic case of the drive, you transfer that energy, which can then fry vital components.

Moreover, some modern components have integrated anti-shock technology that should prevent hardware damage from an unexpected static shock. But just because your drive has shock protection, it doesn’t mean you shouldn’t be wary of affecting other hardware components.

Touch a metal table leg or the case of your computer (do this after discharging your motherboard, as described above). Alternatively, buy an anti-static wristband.

IDE drives haven’t featured in consumer computers for some time. The overwhelming majority of computers and motherboards sold in recent years will focus solely on SATA drives (with a few exceptions, of course).

Both HDDs and SSDs use SATA connectors, so there is nothing to distinguish between the two drive inputs. Your SATA cable will have two connectors, like so:

It is possible to buy an all-in-one, 22-pin SATA cable that combines both connectors (but is less flexible). Your motherboard will have ports like these available:

Make sure you have a PCIe slot available on your motherboard. PCIe slots come in different variants, such as PCIEX16 or PCI2.

It isn’t a case of forcing two SATA connectors into one SATA slot via an adapter. It just doesn’t work that way.

Your new HDD or SSD probably arrived with at least its interface cable (the red cable in our example images above and below). But your drive also needs power.

The below image is a 4-pin Molex SATA power cable: A SATA HDD can arrive with a range of input connectors, allowing you to choose between a SATA power connector (the empty port to the left of the red interface cable, below) or 4-pin Molex connector (the cable on the far right, below).

A reader notes that you should “never use the Molex (4-pin) to SATA power adapter” because “most hard drives and solid state drives require the orange 3.3V wire to supply power for the drive electronics.” This may cause the drives to fail at spinning up or registering in the computer’s BIOS, Device Manager, or Disk Management.

Consequently, some modern HDDs have done away with 4-pin Molex power inputs and now offer just a SATA power input. A SATA SSD will arrive with only a SATA power connector and a data transmission cable.

The following video details the installation process for a desktop PC. Changing the drive on your laptop is also an easy process.

Your existing setup might recognize the new drive if you’re simply adding it for extra storage. But there is a chance it won’t.

Your unallocated drive should be visible on a separate row. If it is an entirely new drive, it will appear as Unknown and Not Initialized.

Windows 10 will promptly create a new partition and format the drive ready for use. If you’re wondering why I specified unchecking the quick format option, here’s why: a quick format doesn’t check the drive for errors or damage.

You might not have to make any changes to your PC or laptop BIOS. However, if your computer doesn’t detect the new drive by default certain BIOS settings will require a tweak.

To launch the BIOS, you have to press a hardware specific key before the computer boots into Windows. The key is usually DEL, ESC, or F1, but it does vary by manufacturer.

Alternatively, consult our guide to entering the BIOS, including a list of commonly used keys by manufacturers. Once you’re in the BIOS, be careful not to change any unfamiliar options.

Carefully check that each cable is well seated in its port at each end and that you haven’t accidentally knocked other cables during the process. If you follow our guide, you should have your new drive up and running in no time and with ease.

Don’t throw it out. Instead, find things to do with your old disk and get a great chunk of good use out of it, even if it’s dead.

If you you are building a desktop PC for the first time or upgrading your storage space for the better, installing a new hard drive can prove to a daunting task for some. While most users these days install SSDs in their PCs, a hard disk drive (HDD) is still one of the most popular storage devices for those who want high capacity at an affordable price.

The process is straightforward and sees you mount the HDD, plug in the cables, and format the drive to make it usable on your computer. We will go through these steps one-by-one, so keep reading.

Internal hard disk drives (HDDs) are designed for internal use in desktops and come in two form factors. You can get 2.5-inch HDDs, like Seagate BarraCuda, or 3.5-inch HDDs, like this popular WD Blue drive.

For a small-size ITX Build, a 2.5-inch HDD is ideal. The internal HDDs in laptops are usually the 2.5-inch kind as well.

Note: In 2022, you should not use a hard drive as your main boot partition for Windows. Using a modern OS such as Windows 10/11 on a hard drive tends to be an unoptimized experience.

Instead, check out the best NVMe and SATA SSDs you can consider in 2023.

Your workplace should be clean, and you must ground yourself before touching your PC components. An anti-static bracelet is a great tool to avoid electrostatic damage.

First, you must open up all side panels of your case and set them aside to gain access to the motherboard. In this guide, we expect you have already installed the power supply (PSU) and the motherboard with its various components in your PC.

We will require it while mounting the hard drive in the PC case as well. Next, locate the 3.5-inch drive mounting bay in your PC case.

Depending on your case though, the drive bay might require you to screw in the drive. Once you find it, position your hard drive in the bay and start to screw it in with the Philips Head screwdriver, and the relevant drive-mounting screws provided with your PC case.

In our installation, we didn’t need any screws, and the HDD simply rests inside the 3.5-inch drive day with nubbins that go inside the screw holes. The hard drive itself rests firmly in place inside the dedicated drive bay of our Cooler Master ATX case.

Note: If you have a 2.5-inch HDD, simply install it in the 2.5-inch drive mount location in your PC case in this step instead of the 3.5-inch one. The other steps in this tutorial will remain the same.

Next, plug in one end of the SATA cable to the HDD. You will notice notches on the SATA port and the cable itself, which align in a specific orientation.

Then, route the cable toward the drive bay of your case, and plug in the SATA power connector to the hard drive.

You can refer to your motherboard manual in case you need help in finding the port. If you have a big graphics card installed, it becomes quite hard to plug in a SATA cable as the ports are usually positioned around the PCI-e slot area where you plug in the GPU.

You hard drive Installation is now complete. We can now move to the next section, where we make our new storage device ready for use.

Boot up your PC and enter the BIOS setup. On most motherboards, the key to enter the BIOS is F2 or Delete.

The POST screen, which shows up when you first start your PC, also lists the keys you can press to enter the BIOS.

The model number and capacity should be listed here. Then, you just need to format it in the next step, which will make it ready for storing data.

Usually, when you install a new hard drive, Windows 10/11 asks you to format the storage device before you use it. When you boot into the Windows OS, there will be a pop-up that asks you to format the drive.

In the rare case that you do not get the pop-up, follow these steps to make your hard drive ready for use. Press the Windows key and type “Create and format hard disk partitions” in the search bar at the top.

In this case, it should show up as “Unallocated Space.” Right-click on your drive and select the “New Volume” option. After that, follow the steps in the wizard to format the drive.

It also includes other alternative methods for formatting a storage device. That’s pretty much everything you need to know about installing a hard drive in your PC.

While there were a few things to keep in mind, and the installation mostly involved mounting the hard drive and plugging in the cables. It wasn’t too hard, right.

It has some free utilities mentioned as well. For further storage expansion, buy one of the best external HDDs listed in this guide.

Hard drives are slightly difficult to install, but it mostly depends on your PC case and whether you have the required SATA cable and power connectors on hand. Some PC cases are designed with hard-to-reach drive mounting locations, so installing a hard drive can be especially time-consuming in these cases.

Installing another hard drive in your PC depends on how many SATA ports you have. You can check this in the motherboard’s manual and make sure to confirm how many SATA power connectors you have available.

HDD is only better for your PC if you have a massive need for storage space. While SSDs cost more, they are more reliable and do not break as often.

While most desktop PCs will accept both 3.5-inch and 2.5-inch HDDs, there are a few small cases and mini PCs that will probably only accept 2.5-inch HDDs. Not every HDD can fit in any PC, and you must confirm the compatibility with your PC case manual.

IBM introduced the first HDD in 1956. The IBM 350 Disk Storage Unit contained 50 magnetic platters.

Its cabinet occupied as much space as two refrigerators and weighed just under a ton. The IBM 350 cost around $35,000 when introduced, equivalent to almost $400,000 in 2023.

Hard drives have evolved quite a bit since 1956. Now, hard drives have greater storage capacities and speeds than ever at a fraction of the cost and size.

That is over ten million times larger than the original HDD. As capacities have expanded, manufacturers have used larger units to describe a hard drive’s storage space.

Using the decimal system, manufacturers define a kilobyte as 1,000 bytes. This definition is called the metric prefix.

It is known as the binary prefix. The difference in definitions leads to the disparity.

Still, users will not have that much space available to them. For example, a 1-terabyte hard drive will hold about 931 gigabytes of data.

The device uses a combination of moving parts to manage data on platters coated with magnetic material. Dozens of components work together to read and write data.

Maintenance, including regular defragmentation and updating, can prolong the lifespan of a hard drive, but failure is inevitable. It is just a matter of time.

In most instances, these noises range from slight humming to muted whirring. However, abnormal acoustics, like clicking, beeping, buzzing, grinding, or whining, can indicate something is wrong with the drive.

It could also stem from a defective PCB or broken port, among other things. Here is a collection of worrisome noises for an HDD.

We examined a standard SATA drive as part of this exercise. It was a WD40EZRZ from Western Digital’s Blue series.

Released in 2015, the WD40EZRZ is a 3.5-inch internal hard drive, holding 4 terabytes of data and registering 5400 revolutions per minute. Ultimately, we chose the WD40EZRZ because it is a popular model with a conventional design.

The housing is a durable case that shelters the drive’s components. The housing is made of aluminum to provide discharge protection and shield the drive from electromagnetic interference.

State-of-the-art filters screen destructive substances like dust from entering the housing and damaging the device’s sensitive components. Though similar, the design of a desktop computer hard drive, like the WD40EZRZ, differs from an external hard drive.

As a result, external hard drives have different controllers, interfaces, and power supplies to support that usage.

Dozens of components work together to read and write data. One failure affects the entire drive.

It is just a matter of time. Despite incorporating foam pads and rubber grommets to reduce noise, functional hard drives still produce sounds.

However, abnormal acoustics, like clicking, beeping, buzzing, grinding, or whining, can indicate something is wrong with the drive. The failure could be mechanical, such as a torn read/write head, a worn actuator arm, a scratched platter, or a stuck motor.

Here is a collection of worrisome noises for an HDD. The following list details the main components inside the hard drive.

HDDs would not function without them, starting with the component that stores the device’s data.

A platter is a circular disk that stores data. Manufacturers often use an aluminum or glass substrate to make platters.

At the same time, the platter’s surface must be smooth. Even the slightest imperfection could cause catastrophic failure.

The film allows for the recording and retrieval of data through a series of magnetic interactions. Manufacturers place a carbon-based overcoat onto the disk after depositing the magnetic material.

Then, manufacturers divide the platter’s surface into billions of magnetic domains. Each domain represents a bit of data.

Altering that orientation modifies the device’s data. Multiple platters are stacked on a spindle to increase the surface area.

Platters are split even further to improve capacities. The disks consist of concentric circles called tracks.

For reference, the thickness of a regular sheet of paper is about 100,000 nanometers. A track features dozens of sectors.

However, some models place more sectors in the outer tracks of a platter. Since outer tracks are longer, more sectors fit inside them.

Most modern HDDs have 512-byte sectors. To reach 4 terabytes, a hard drive needs almost eight billion sectors.

A group of sectors is called a cluster. Clusters are the smallest allocation unit and consist of consecutive sectors.

When a file is accessed, created, or edited, the hard drive addresses the entire cluster instead of an individual sector. As a consequence, clusters can have wasted storage space and contribute to fragmentation.

A significant number of modern devices adopted shingled magnetic recording (SMR). Compared to the perpendicular alignment of conventional magnetic recording, an SMR drive compresses tracks, meaning each circle overlaps like shingles on a roof.

Other recording technologies will emerge in the future. In 2023, storage giant Seagate announced plans to release the world’s first 30-plus terabyte HDD to a data center.

Developed over decades, HAMR drives have a nanoscopic laser diode that applies heat to the platter surface to manipulate magnetic grains. The heated grains are stabilized through a complex series of electrical processes, achieving smaller bit sizes without magnetic interference.

Regardless of the structure of the platters, the hard drive still needs a mechanism to access their data.

A read/write head is an ultra-precise instrument, given the compact arrangement of parts within a hard drive. Each head is assigned to a single platter surface.

The slider supports the read/write head as it flies over the spinning platters. When in use, a drive’s platter completes thousands of revolutions per minute.

When in motion, the slider creates a thin air cushion underneath the head, ensuring the elements safely hover above the platters. In most drives, that distance is 3-10 nanometers.

During data retrieval, a microscopic read element at the front of the slider detects variations in the platter’s magnetic domains. As the platter spins, its magnetic field shifts, creating faint electrical signals within the read element.

The microscopic write element, also located at the front of the slider, applies an electrical current to its coil and generates a small magnetic field. That magnetic field interacts with particles on the platter.

Together, these components allow the device to read and write data. However, read/write heads cannot move on their own.

The actuator arm positions read/write heads over specific tracks on a platter. An.
