The lab is currently runing MS-DOS 3.1. Recently, we tried to upgrade the lab to MS-DOS 3.2 and found a problem. MS-DOS 3.2 was unable to detect when we switched disks in our HP 9121 floppy disk drives. This led to corrupted FATs and data blocks. Does anyone have any ideas on how to fix this problem? We would very much like to upgrade to MS-DOS 3.2 because -- so we are told -- we could then write 3.5' floppies which would be compatable with the rest of the PC world. Thanks, Jim Barbour (jwbarbour@clipr.Colorado.EDU)
