Description: Secure file deletion
 Recovery of supposedly erased data from magnetic media is easier than
what many
 people would like to believe. A technique called Magnetic Force Microscopy
 (MFM) allows any moderately funded opponent to recover the last two or
 layers of data written to disk. Wipe repeatedly writes special patterns
to the
 files to be destroyed, using the fsync() call and/or the O_SYNC bit to
 disk access.
