Testdisk has saved my butt on numerous occasions, a combination of my own inattention, things just going wrong, and even an XP install deciding that it would format my ext3 storage drive instead of the drive I told it to. In the case of the latter, despite the drive undergoing a full-format to NTFS, it managed to recover all my files, nearly a terabyte drive full of of them, and give me back my ext3 partition. It's one thing I swear by. :)
