These tell you quite a lot. A small point. I believe that there is no difference in the physical formatting between disks formatted on DOS 2.x upwards with and without the /8 switch. The difference is only in the BIOS paramter block in the boot sector, which says to only use eight sectors/track. Of course, real DOS 1.x disks do only have 8 sectors/track! -- Bob Eager rde@ukc.UUCP rde@ukc ...!mcvax!ukc!rde Phone: +44 227 66822 ext 7589
