I don't know about that.  I've low level formatted IDE, MFM, RLL, and SCSI drives with no problems,
and just fdisk it with OS/2 or Linux's fdisk util.  But I am sure that a magnet would still do
damage.  If you want the data really badly, send the drive to ontrack data recovery or a similiar company.
