Yes, formatting is a quick operation, it just sets up a blank filesystem, it doesn't actually overwrite the storage area of the disk. That's why formatting to XFS may, possibly, hopefully, be somewhat recoverable, since the actual data wasn't overwritten, just the table of contents. We just have to sort through all the raw data that doesn't have any references to tell which file is what and where the files start and end. ReiserFS is actually pretty robust at being able to recover from this sort of thing, we just have to convince it to try. All file recovery software does roughly the same thing, walks the entire surface of the disk to try and piece together files from a mess of bits with no valid table of contents. Some files have distinct markers that make it easier to figure out, but it all comes down to how well it can make good guesses as to what went where. Quote Link to comment
