Dear All I have a hard disk which has dynamic drive overlay on it because it was originally in an older computer. I wish to use this disk in a new computer I have built and do not need dynamic drive overlay as the bios can cope with larger hard drives. Everything on the disk has been backed up using microsoft backup (Win98SE). if I reformat the hard disk and then copy back all the backup CD's will the dynamic drive overlay be reinstalled along with all the data etc or is 'DDO'treated as part of the formatting process rather than data and not backed up?
