I accidentally deleted a volume in Windows Disk Management. Is there an easy way to undo that action? Or do I have to use a file recovery tool?

If you can recreate the partition the same exact size, you can then get the backup boot sector from the end of the volume. See kb article 245725 from microsoft.

You can't undo it in Windows.

You need to either restore your partition table from a backup you may have made, or use recovery tools like FindNTFS or similar.

Thanks. Findtfs is really complicated, I didn't dare try it out. I tried which is free, but this works only with 32 bit windows. Then I tried various other tools, but they were mostly crap. Then I tried "Active@ Partition Recovery" (, which worked great and was really fast. Unfortunately it's not free, but there is a demo to see if it will work in your case. – Michael Böckling May 22 '10 at 15:44

TestDisk has worked well for me in the past, when I stopped a partition resize in the middle of it (bad idea).
