Something freaky has happened. My 3rd disk's partitions are gone. I had a 1) HURD 2) Windows 3) DragonFly. Now wanting to play some games i went to boot WIndows and i found out the DragonFly partition is now covering the whole disk. Does MBR have a modification timestamp? If yes, how to retrieve it? If no, what can i do?

I'm not aware of a way to recover the MBR -- it's not copied to any backup space when overwritten (intentionally, accidentally, or via software bug).

You may be interested in gpart, which will attempt to guess the partition boundaries:

You probably know this already, but don't write to that disk! The more you write to it now, the less likely that partition recovery will succeed.
