I know of at least one case where, when the disk is formatted at 1024 bytes/sector, track 0 is actually 128 bytes per sector. You might wish to check with the 1791 (I think that's whats in the CCS) controller chip specs for the track format. Also, try some of the utility programs that should rely on the disk parameter block. They are generally considered operable regardless of disk density. Some of these are DU (A disk hacking utility), and SAP (sort and pack directory). Be sure to use the latest versions and test them on non-critical disks. Good luck, David
