Depending on the drive, the manufacturer probably either has a special format utility, or if not, you should be able to pop it into a machine with an old low level routine in ROM (as long as it truly supports the actual number of cylinders, heads, etc) that the drive has, and do it that way. I used to have to do that a fair bit with old Fujitsu IDE drives that didn't automap new bad sectors.... They would map them during a low level format (using say, the old AMI ROM routine) just fine. Most DOS-based utilities won't work because of limitations on their INT-13 handling of the disk (can't do more than 1024 cylinders, etc), although there is probably something around somewhere that can do it right. I suppose a quick program to talk directly to the drive would work too. Later...... <Doug>
