Ahh, neat. Two sectors of ECC can fix one that is completely destroyed? I was under the impression that you could only fix a few corrupted bits, not an entire sector, but I suppose if you add enough ECC... I take it that someone has already made sure that the misbehaved software only uses a single sector? _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel
