For future reference there's an awesome utility within Linux called
dd.
You can use it to write zeros to every bit on a drive. This includes the space occupied by the MBR.
Where # is the drive you want to zero:
Code:
dd if=/dev/zero of=/dev/hd#
The drive should not be mounted when you start the process, and you should direct 'of' to the
drive and not to individual partitions (unless you want to zero a partition of course.....). You'll need to format the drive when you're done and you
will lose
every piece of data on the drive
