Windows 7: Mystery 3MB Partition still showing after full disk wipe

Have you tried DISKPART "Clean All" yet?

Hi TVeblen, I'm sorry I didn't respond to your original post. I've run Clean All in Diskpart a few times now, but it didn't have any effect on the partition, I'm afraid.

The more trouble I have removing this partition, the more convinced I become it's part of a rootkit.

Windows 7 Home Premium 32 bit

I am surprised to learn that HDAT2 did not find anything.

The only thing left for you to try is to use Atola's HDD Capacity Restore Tool - my post #9 - hooking up the HDD onto a 32bit system.

(If you have no means to do it, you may seek help from a neighbourhood computer shop to do it for you.)

I looked back at your first post and noticed that this mystery drive is Virtual Hard Disk.

Does this 3MB partition show up in any other program or utility? If not, it may be a virtual drive created for the use of Active Partition Manager.

Just a guess. But seeing it is a virtual drive just makes me think it does not really exist at all on the physical hard drive.
