Here is the general situation.
My organization has a number of data tapes (backup tapes) that we need to dispose of. We have purchased a media degausser and are in the process of degaussing all of the tapes.
My question is this. Is there a method/utility/suite that can verify that the data has been erased fully? In other words is there a utility that can read raw data off the tapes and reassemble the data into files? That way if any files were shown it could be concluded that the data is not fully erased.
