Step by step guide to fix an external hard drive that's not showing up on Windows
Before troubleshooting using the steps below, try restarting your computer or external hard drive. Although it appears simple, rebooting devices often fixes lots of technical issues.
1. Check the physical connection
Make sure your external hard drive is connected properly to your computer:
- Disconnect and reconnect the hard drive to your computer.
- Reconnect the hard drive to a different USB port on your computer.
Use a different cable to connect your hard drive and computer.
2. Update or reinstall drivers
Outdated or corrupt drivers can prevent your external hard drive from being recognized. Update the drivers with these steps:
- Right-click the Start button at the bottom left corner of the screen and select Device Manager.
- Click the dropdown arrow beside Disk Drives. Right-click your external hard drive, click Update driver, then select Search automatically for drivers.
In case this isn’t resolving the problem, try this:
- Return to the Device Manager and expand Disk Drives.
- Right-click your external hard drive and click Uninstall device. Confirm by clicking Uninstall again.
- Reconnect your hard drive to initiate a new driver installation.
3. Format the hard drive
Windows can’t recognize hard drives with unsupported formats like APFS (Mac) or ext4 (Linux), in which case you’ll need to format the drive. Note that formatting a drive will erase all content on it:
- Right-click the Start button at the bottom left corner of the screen and select Disk Management.
- Right-click your external hard drive and select Format. Click OK to begin formatting your hard drive.
- Reconnect your hard drive.
4. Use Windows CheckDisk
The Windows CheckDisk utility helps to troubleshoot issues related to disks. These repairs can sometimes erase data, so back up your drive before following these steps:
- Press Windows + S and type Command Prompt. Right-click it and select Run as administrator.
- Type chkdsk /f followed by the letter of your hard drive. In my case, that’s chkdsk /f E:.
- Hit Enter.
- Wait till the scanning and examining are done, and you see Total Duration.
CheckDisk may take time to complete the scan and repair if there are many errors, and you may have to restart your computer once it finishes running.
5. Enable the drive or create a New Simple Volume
You’ll need to enable your hard drive if it’s offline:
- Right-click the Start button at the bottom left corner of the screen and select Disk Management.
- Towards the bottom of the screen, check if it says Offline under your disk in the gray box.
- If it does, then right-click the gray box and select Online.
If it says Unallocated beside your hard drive, follow these steps to format it:
- Right-click the gray box with your hard drive.
- Select New Simple Volume and follow the steps in the Wizard.
6. Assign a drive letter
If your hard drive doesn’t have a drive letter in Disk Management, assign it one:
- Open Disk Management (right-click the Start button at the bottom left corner of the screen and select Disk Management).
- Under Volume, right-click your hard drive and select Change Drive Letter and Paths. Click add, assign a letter, and click OK.
