The only safe way to delete a computer file is to erase it and overwrite
it with new data several times so that no traces survive.
But if the floppy drive or tape drive that overwrites
the data is aligned differently from the drive that originally wrote it, data may be relatively easy to recover with special software or altered drives.
This multiple overwrite
process (optionally up to eight overwrites
) renders the original data unrecoverable, even by sophisticated laboratory techniques applied to hard drives removed from the control unit.
WP# Pin secures the information stored on the ADM from any unintentional data overwrites
