Is the partition table gone? He overwrote hda1, not hda (although,
with the FAT gone, MS-DOS doesn't know what data is where, so the data
is probably unrecoverable)?
If you want, I know the older versions of Norton let you hex edit the
data, but you would have to go through all the data by hand, & hope
you can recognize programs, data, etc. Massive pain, often it's
easier to recreate from scratch, then backup.
