i've tried, though long time ago, to rawrite the boot and supp images (from red hat cd-rom) to 2 boot disks. there were working fine. but when i try to do the same (images from sunsite this time and so is the rawrite program) it always abort with a message saying that there is bad sector no matter what (old or new) disk i used. just wondering what is happening. any way to get around this. i am pretty sure that not all the disks i tried have bad sectors. thanks in advance.
