"Windows can't access the disk" is one of the most common issues that can occur due to several reasons. Since there could be several causes behind the problem, there are many solutions available as well. You just need to try the solutions one-by-one until the problem is solved.

1How to Fix "Windows can't access the disk" Issue?

1Check the Connection

One of the most common causes behind "Windows can't access the disk" is loose or improper physical connection to the hard drive. So, you should turn off your PC and make sure that the connection is okay:

  • 1. Turn off your computer and open the case. Then see if the cables connecting your hard drives to your computer are all properly connected.

  • 2. If you have external hard drives, unplug them one-by-one and plug them on different USB ports.

  • 3. You should also check the USB ports to make sure there isn't any power supply issue causing the hard drives to become inaccessible.

2Change the Drive Letter

"Windows can't access the disk" error can also occur if the 'drive letter' assigned to your hard drives have any inconsistency or mismatch. If that is the case, then you will need to use Disk Management and assign the proper drive letters to your hard drives.

The process is quite straightforward. You just need to make sure that you assign different drive letters to each of your drives that aren't already in use. You may also need to restart your computer after assigning letters to make the changes effective.

Follow these instructions:

  • 1. On your Windows PC, launch Disk Management via the Start Menu.

  • 2. Once Disk Management is launched, it will list all your hard drives connected to your computer. From that list, choose your hard drive that cannot be accessed and right-click on it.

  • 3. Then select 'Change Drive Letter and Paths' from the right-click menu.

  • 4. Now click on the 'letter' that is currently associated with the drive and select the 'Change' option.

  • 5. Next, choose a 'new drive letter' from the drop-down menu. Make sure to select an appropriate letter for the drive. Then click 'Ok' to continue.

  • 6. Now restart your computer. The hard drive should be accessible now.

3Run Disk Check

There could be another major cause behind 'Windows can't access the disk' issue and it is related to the bad hard drive sectors. If there are some sectors of the hard drive that are damaged or corrupted, then you will need to quickly repair them by running Disk Check. Windows has a special program just for this purpose. It is called the chkdsk scan. However, keep in mind that repairing bad sectors via chkdsk may result in data loss.

Follow these instructions:

  • 1. Launch Command Prompt on your computer. You can launch it from the Start Menu or run it from the Run feature of Windows. Make sure to launch CMD as administrator.

  • 2. Once the CMD window appears, input the drive letter and press Enter.

  • 3. Next input chkdsk /r and press Enter to execute the chkdsk command. In certain cases, you may be asked to dismount and schedule chkdsk on next restart, if that is the case, then press Y and then press Enter to start the chkdsk scan.

  • 4. Once the chkdsk scan is completed and the bad sectors of the hard drive are repaired, exit the CMD window and restart your computer. The hard drive should be accessible now.
