Linux does know how to detect Ontrack, and looks at the re-located
partition table. I know that I can remove it from the partition sector
easy enough using either LILO or "fdisk /mbr" from a clean DOS floppy,
but I want to move the real partition table back to the start of the disk
too. [Actually, linux fdisk must know about DDO too, because I've repartitioned
the disc with it with DDO installed.]
If I do trash the partition table, I can always re-enter the values
if I save them first.
