Steps to Unmount a Volume in Windows

Mounting a disk makes it accessible by the system. Unmounting a disk prevents your system from accessing any data and there is no risk of your disk getting disconnected during data transfer. Hence, before you remove your external storage device like a USB flash drive, you should first unmount it to avoid data corruption.

Once your drive is unmounted, other storage devices can access it. Note that the file system will be inaccessible during regular reads and writes.

How to unmount a volume?

Let us see the procedure to unmount a volume using Disk Management.

  • Press Windows+X A context menu opens. Choose Disk Management.
  • In Disk Management, select the volume that you want to unmount. Right-click that volume and select Change Drive Letter and Paths.
  • Select the volume’s drive letter and click Remove.
  • A prompt appears “Are you sure you want to remove this drive letter?” Select Yes.
  • If you are running any programs or applications from that volume, an additional prompt appears “The volume is currently in use. Do you want to continue?” Close all the programs or applications that are using the volume and click Yes. Windows will restart for the volume to be completely unmounted.
  • Go back to Disk Management. You can now see that your partition does not have a drive letter.

Your partition is now not affected by accidental writes.

If you want to move the data to a removable disk, you should mount the volume again.

  • Right-click the unmounted volume and select Change Drive Letter and Paths.
  • Click on Add. Now choose to Assign the following drive letter. You can select a letter from a drop-down on the right. Once you have selected a letter, click OK.
