An external storage drive becomes unallocated when its file system turns corrupt. This happens when any virus harms the file system, or when the disk drive has bad sectors. The unallocated drive is not visible in File Explorer, but its status can be verified from Disk Management. Also, all the data stored on the unallocated drive can?t be accessed. You need to fix the unallocated disk drive first to access this data.
In this blog, we?ll share troubleshooting techniques to fix an unallocated disk drive so that it can be reused. And, also share methods to recover data from the unallocated drive.
