magicrescue 1.1.8-1 (powerpc binary) in ubuntu lucid

 Magic Rescue scans a block device for file types it knows how to recover
 and calls an external program to extract them. It looks at "magic bytes"
 in file contents, so it can be used both as an undelete utility and for
 recovering a corrupted drive or partition. As long as the file data is
 there, it will find it.
