How to Remove a Hard Drive From a Computer (Desktop PC Guide)

Whether your PC died and you want your files back, you’re recycling an old machine, or you’re shipping a drive off for recovery, knowing how to remove a hard drive from a computer is a useful skill. On a desktop it usually takes ten or fifteen minutes and a Phillips screwdriver. This guide covers desktop towers: 3.5” and 2.5” SATA drives and M.2 SSDs. If you’re working on a laptop, see our guide to getting files off a dead laptop, which covers laptop drives and adapters in detail.

Before you start

You’ll need:

• A Phillips #2 screwdriver (and a smaller #1 or #0 for M.2 screws).
• A clear, dry, well-lit work surface, ideally not carpet.
• A small container for screws.
• Masking tape and a pen for labels.
• An antistatic bag to store the drive afterward, if you have one.

One important note before you begin: only remove the drive, never open it. A hard drive’s sealed case should stay closed. Opening it outside a cleanroom exposes the platters to dust and almost always makes professional recovery harder.

How to remove a hard drive from a computer, step by step

1. Shut down and unplug

Shut Windows down normally if you can. Then switch off the power supply (the rocker switch on the back, if there is one) and unplug the power cord. Disconnect the monitor, USB devices and network cable too. Press the PC’s power button once with the cord unplugged to drain any remaining charge.

2. Ground yourself

Static discharge can damage electronics. Touch a bare metal part of the case before handling anything inside, and repeat now and then as you work. An antistatic wrist strap clipped to the case is better if you have one. Avoid working in socks on carpet.

3. Open the case

Most towers have a removable left side panel (viewed from the front). It’s usually held by two thumbscrews or Phillips screws at the back, then slides backward or swings out. Some cases use a glass panel with screws at the corners. Some prebuilt PCs from Dell, HP and Lenovo use a latch or release button instead. Check your model’s service manual if it’s not obvious.

4. Find the drive

Look for:

• 3.5” hard drives in a drive cage or bays, usually at the front of the case, often in trays or sleds.
• 2.5” SSDs or hard drives on mounting brackets, behind the motherboard tray, or in small dedicated bays.
• M.2 SSDs lying flat on the motherboard, often under a metal heatsink or a cover near the graphics card.

Your PC may have more than one. If you’re not sure which drive holds Windows or your files, our guide to checking what hard drive you have can help you match model names before you pull anything, assuming the PC still boots.

5. Label everything

If there’s more than one drive, put a piece of tape on each one noting which SATA port or slot it came from and what you think is on it (“Windows SSD,” “D: photos”). This matters most if the drives were part of a RAID set, where order can be important.

6. Disconnect a SATA drive

A SATA drive has two cables:

• A thin, flat SATA data cable that runs to the motherboard. It often has a small metal latch; press it while pulling straight back.
• A wider SATA power connector from the power supply. Grip the plastic connector, not the wires, and pull straight out. Don’t rock it side to side hard; the plastic tab on the drive can snap.

Then free the drive from its mount. Depending on the case, that means removing two to four screws on the sides or bottom, squeezing the clips on a tool-less tray and sliding it out, or unscrewing a 2.5” bracket. Keep the screws.

7. Remove an M.2 SSD

1. Remove any heatsink or cover over the slot (usually one or two small screws).
2. Undo the single standoff screw at the far end of the SSD. The drive will spring up at an angle of roughly 20 to 30 degrees. That’s normal.
3. Slide it straight out of the slot at that angle. Don’t bend it.

Put the tiny screw somewhere safe; they’re easy to lose and specific to the board.

Storing or shipping the drive

• Put the drive in an antistatic bag and wrap it in bubble wrap or foam.
• Handle hard drives gently. Avoid dropping or knocking them, especially if they’ve been failing.
• Don’t stack heavy things on it, and keep it dry and at room temperature.

Reading the drive on another computer

You have two options:

• USB adapter or enclosure. A USB-to-SATA adapter works for 2.5” drives. A 3.5” drive needs an adapter or dock with its own power supply. M.2 drives need an enclosure that matches the type: NVMe or SATA. Our dead laptop guide explains how to tell them apart.
• Install it inside another desktop as a second drive, connected to a spare SATA port or M.2 slot.

When it’s connected:

• BitLocker: if the drive was encrypted, Windows will ask for the 48-digit recovery key before showing files. See find your BitLocker recovery key.
• Don’t initialize or format. If Windows says the disk is unknown or not initialized, or asks you to format it, click Cancel. Our guide on disk unknown, not initialized explains why.
• Copy, don’t repair. Copy your important files off first, before running CHKDSK or any repair tool.

When to stop

Stop and power down the drive if it:

• Clicks, grinds, beeps or buzzes.
• Doesn’t spin up or isn’t detected at all on a second computer.
• Shows up but copying is extremely slow or keeps failing.

Those are signs of a hardware fault. Repeated attempts can turn a recoverable drive into a much harder case.

The bottom line

Removing a hard drive from a desktop is straightforward: power down and unplug, ground yourself, open the side panel, label the drives, disconnect the SATA data and power cables (or undo the M.2 standoff screw), and free the drive from its bay. Store it in an antistatic bag, have your BitLocker key ready, and never open the drive itself.
