Some harddrives are having a part of the bios in a protected sector. If you delete it, the drive isn't usable any more. The next question is the strength of the magnet. You need the same or stronger magnetic field to write to the surface than the magnetic field you've used to delete. After all it's theoretical possible to read some fluctuations of the magnetic field to restore your deleted data. It's better to overwrite the harddisk several times with random data to be shure everything is really deleted. > bye/B$H Alex -- The 5th commandment: A Discordian is prohobited of believing what he reads. _______________________________________________ Full-Disclosure - We believe in it.
