All, I'm trying to format a 44 meg syquest with 3.0 CrossDos with no luck. Can anyone help. I've gotten as far as changing a PC0 mountlist to match the syquest drive, it formats ok but ends with message saying it can't format cyl 1266. I've tried other things to get it to format all the way, then it can't initialize it. Thanks for any help Russ
