recovering from the unthinkable

[Joel Rees]

The excuse: Trying to get all my precious files from the usb drive
after 10:00 PM.

So, is anyone willing me to remind me of the name of the program that
goes searching through a drive that has been the victim of the old rm
-f and re-constructs the file system? I'm pretty sure I've used it
before, when I lost an lvm volume once.

Can't remember what it was called, and searching via google for "disk
recovery tools" now returns a whole lot of links I sure wouldn't want
to trust.
