What happens when an NVMe drive fails and how to replace it

An NVMe drive that has failed or is failing will show signs before it stops working entirely: your computer takes much longer to start up, programs freeze when you open them, or you see error messages about disk problems. When this happens, the drive itself — not the data on it — has degraded beyond use. Replacing it means removing the old drive from its slot on your motherboard and installing a new one in its place, then reinstalling your operating system and restoring your files from a backup.

The physical replacement takes about five minutes. The time-consuming part is preparing: backing up your files, obtaining a new drive, and having a way to reinstall Windows or macOS afterward. If you have never opened your computer case before, the process is straightforward, but you will need to ground yourself against static electricity first.

Key Takeaways

  • An NVMe drive slots directly into your motherboard and requires no cables, making it simpler to replace than older hard drives.
  • Before you remove anything, back up your files to an external drive or cloud storage, because the old drive will be erased during the replacement process.
  • You will need a Phillips head screwdriver, a new NVMe drive of the same physical size as the old one, and a way to reinstall your operating system afterward.
  • After installing the new drive, your computer will not start until you reinstall Windows or macOS using a bootable USB drive or installation media.
  • Grounding yourself by touching a metal part of the case before you work prevents static electricity from damaging the new drive.

Backing up your files before you start

The old drive will not be usable after you remove it, so everything on it needs to be copied elsewhere first. If you have been using Windows File History or macOS Time Machine, those backups are already done — you can restore from them after the new drive is installed. If you have not been backing up automatically, copy your important files to an external hard drive or USB drive now. This includes documents, photos, videos, and any files in your Downloads folder that you want to keep.

Cloud storage like Google Drive, OneDrive, or Dropbox also works, but uploading large files over the internet takes time. An external drive is faster if you have one available. Do not skip this step — once the old drive is out, those files are gone unless you have a copy somewhere else.

Gathering the tools and parts you need

You will need a Phillips head screwdriver (the cross-shaped one), a new NVMe drive, and a way to reinstall your operating system. The new drive must be the same physical size as the old one — most modern computers use the 2280 size (22 millimeters wide, 80 millimeters long), but some laptops use 2242 or 2230. Check your computer's manual or look at the old drive before you remove it to confirm the size.

For reinstalling your operating system, you will need either a bootable USB drive with Windows or macOS on it, or access to your computer manufacturer's recovery media. If you have a second computer available, you can create a bootable USB drive using Microsoft's Windows Media Creation Tool or Apple's macOS installer. If you do not have a second computer, contact your manufacturer before you remove the old drive — they can send you recovery media or tell you how to create it.

Opening the case and locating the NVMe slot

Power off your computer completely and unplug it from the wall. Wait a few seconds, then touch a metal part of the case with your bare hand to discharge any static electricity from your body. This prevents the static from jumping to the new drive when you handle it.

Remove the side panel of your case using the Phillips screwdriver. On most desktop computers, two or three screws hold it in place. On laptops, the process varies — some have a single panel that slides off, others have multiple screws underneath. Consult your computer's manual if you are unsure.

Locate the NVMe slot on your motherboard. It is a small horizontal slot, usually near the center or edge of the board, and is labeled M.2 or NVMe. There may be a small heatsink or label covering it. If there is a heatsink, it usually lifts off or unscrews. The old drive will be sticking up at a slight angle from the slot.

Removing the old drive and installing the new one

Gently press down on the end of the old drive until you hear a small click — this releases the retention clip. The drive will pop up slightly. Grasp it by the edges (not the gold connector) and pull it straight out at the same angle it was sitting. Set it aside; you will not need it again.

Take the new drive out of its packaging and hold it by the edges only. Align the notch in the drive with the key in the slot, then insert it at the same angle the old one was sitting (about 30 degrees from flat). Push down gently until you hear the click again — the retention clip will hold it in place. If your motherboard has a heatsink, slide it back on and find it with its screw.

Close the case and plug the computer back in. Do not turn it on yet — you still need to reinstall your operating system.

Reinstalling your operating system

Insert the bootable USB drive or recovery media into your computer and turn it on. Your computer should automatically boot from the USB drive instead of the internal drive (if it does not, restart and look for a boot menu option, usually shown on the screen as you start up — often F12, F2, or Esc, depending on your manufacturer).

Follow the on-screen prompts to reinstall Windows or macOS. The installer will recognize the new drive as empty and will format it automatically. Choose the option to do a clean install rather than an upgrade. The process takes 20 to 45 minutes depending on your internet speed and which operating system you are installing.

After the installation finishes, your computer will restart and you will see the setup screen for your operating system. Complete the initial setup, then connect to your internet. If you have a backup from File History or Time Machine, you can restore your files from it now. Otherwise, copy your backed-up files from the external drive back onto your computer.

Verifying the new drive is working correctly

Once your operating system is fully installed and your files are restored, check that the new drive is recognized and working. On Windows, open File Explorer and confirm that your C: drive shows the correct total capacity. On macOS, click the Apple menu, select About This Mac, and check that the storage shows the correct size.

Run a few programs and open some files to make sure everything responds normally. Your computer should feel as fast as it did before the old drive started failing. If you notice the same slowness or freezing, the problem may not have been the drive — contact a technician to investigate further.

Frequently Asked Questions

Can I use the old NVMe drive in another computer?

Not reliably. A failing drive will continue to fail in any computer. If the drive is not actually failing but you are replacing it for another reason, you could potentially use it elsewhere, but testing it first is difficult without specialized tools. It is safer to recycle it or dispose of it according to your local electronics waste guidelines.

What if my computer does not recognize the new drive after I install it?

Restart the computer and check the BIOS or UEFI settings (usually accessed by pressing Delete, F2, or F12 during startup). Confirm that the NVMe slot is enabled in the settings. If it is already enabled, the drive may be defective — try reseating it by removing and reinstalling it firmly. If the computer still does not recognize it, contact the drive manufacturer or your computer's support line.

Do I need to install drivers for the new NVMe drive?

No. Windows and macOS recognize NVMe drives automatically and install any necessary drivers during the operating system installation. You do not need to read or install anything separately for the drive itself.

How long does the entire replacement process take?

The physical replacement takes about 5 to 10 minutes. Backing up your files beforehand can take anywhere from 30 minutes to several hours depending on how much data you have. Reinstalling the operating system takes 20 to 45 minutes. Restoring your files from backup takes additional time depending on the backup size and your storage speed.

What if I do not have a backup of my files?

If the old drive is still readable, a data recovery service may be able to retrieve your files, but this is expensive and not always successful. If the drive is completely unreadable, the files are likely unrecoverable. This is why backing up before you remove the drive is important — once it is out, you cannot get those files back without professional help.
