External hard drives are small, portable, and convenient. People use external hard drives as important data/file storage devices or backup devices. To store different types of data, and out of convenience, external hard drives are divided into several parts.

Generally, we call it partitions or volumes. Some users will set a partition to store data, another to save backups, etc. However, you accidentally deleted volume in Disk Management and don't know how to recover deleted volume on external hard drive.


If you are experiencing a similar issue, don't worry about it too much, since inadvertent deletion is not a rare case among external hard drive users. And this article will offer you an effective method to fix it.

Accidentally deleted volume in Disk Management


Repurposing a 3TB disk for use as a USB external hard drive but accidentally deleted some partitions. Now how do I recover the missing 2+TB Volume that I deleted via Disk Management?


- Question from Microsoft Community


Can a deleted volume be recovered?

Answer: Sometimes yes, sometimes no.

You may find the external hard drive not showing up after deleting volume, and if you go to the Disk Management tool, you may find it becomes unallocated. At this time, some users, perhaps, are going to format it, or try to recreate a new partition.

Attention please, this is very dangerous for your deleted volumes and data! Because the data will be logically deleted when you delete a partition in Disk Management, and the space left will be marked as “unallocated”, waiting for new data to overwrite.


Vice versa, the deleted volume can be recovered as long as no more operations are done to the external hard drive after deletion. Then, you can choose to perform unallocated partition recovery.

Matters related to your recovery rate

If you want to recover lost partition on external hard drive with the data in it kept, these are of vital importance.

  • Do not try to reformat the unallocated space.
  • Do not add more files to the deleted volume.
  • Never try to rebuild the partition table.
  • Do not try to create new partitions.
  • Do not use the “assign letter” command to give a name to the volume.

In a nutshell, please stop using the external hard drive right after deletion. You can then follow the tutorial below to perform lost volume recovery.
