Any modern drives that do this? E.g.? If this is a real concern
(must be pretty rare as I've never seen it mentioned in dd disk
mirroring discussions) he could still dd the whole drive if he took
the precaution of backing up the first xx bytes off the disk being
copied to. I thought drives were pretty flexible/forgiving, I've
temporarily made a 6.4 gig drive into a 16meg drive with totally
wrong settings in bios and it worked fine.
