TestDisk cannot find the partition that became unallocated

#1 Post by AndyII » 13 Mar 2017, 12:28

I had a hard disk partitioned into C:, D:, and E:. I hadn't used E: in a while so I didn't notice it missing until I tried to save something to it yesterday.

It is 763.04 GB and is not listed as Unallocated.

I ran TestDisk in Deeper Search and it still finds nothing. I have (or had) dozens of downloads on this drive.

Is there something I can do to recover this partition? I do have a backup from 2015 but I'm not sure if I saved anything since then that I'll lose if I don't try the recovery first. If not recoverable, I could use some instruction on allocating this space to a drive letter. It's been a long time since I've done that.

Please help.

You can use Window Disk Manager to create a partition from the unallocated space.

How does that get my data back? How can I get that data back if TestDisk can't find it?

You can use PhotoRec but it will not recover the original filenames or directory structure.
If you run it on the new partition, you may have to enable the expert mode in Options and choose a blocksize of 512 bytes, use the default values otherwise.

Okay, thanks. I'll call that Plan B.

I'm still hoping to find something that will just get the partition back in one piece.

TestDisk didn't find your lost partition after deeper search, so you have to go to plan B.
