The solution for this situation will first format the volume and then wipe this partition, Partition Expert, the disk manager program, can be the alternative program to Windows Disk Management, Download and directly run it from the portable 64-bit edition (32-bit edition is also available)
In the main interface, click on the volume that can’t be accessed and choose the function Format Volume from the sidebar, then in the format window, choose the file system, cluster size, and leave the
Quick Format option as checked, and click OK. Or if you had no clue of the above terms, just click OK and using the default settings,
Then right-click on the formatted partition and select Wipe Volume from the menu, then confirm this operation to proceed. In the wipe window, choose a wiping algorithm in the list, where we have 5 types of wiping schemes, 3 of which are fast overwriting, the other two are DoD wiping methods. Don’t Know how to choose? use the default one will be fine too.

Why don’t you just Wipe Volume with this program?
Well, Wipe Volume is fine too, but Wipe unallocated space is a little bit faster, especially when we use the default one-pass overwriting method to wipe. And I just want to show you this function to make unallocated space clean.
