When they say it can be retrieved if a drive has been formatted up to 30 times, they are probably a little ambitious. Most formats are done using "format c:" and nothing else. Again, this just removes the pointers. When I redo a drive, I run a zero fill 3 times over it. Then to test whether or not data has been completely erased, I run the drive on my Encase machine. If anything shows up I erase some more. So your FAST person may be a little ambitious in his/her claims, I know that just regular formatting can leave a drive recoverable up to about 5 times anyway.

I had an interesting conversation today with someone from FAST (Federation Against Software Theft) They pretend not to be a snitch wing of the BSA.

Really? Wow. Please email me about the tools they are using, but that's probably classified.
