DOS will not handle more than 1024 cylinders without special drivers (such as Disk Manager's dmdrvr.bin). In your case, fdisk used 1024 of the 1036 cylinders--the 12 cylinder loss was too small to notice their absence. My drive has 1416 cylinders, which loses 392 cylinders when used with DOS with no translation. I had to get a RLL controller that supports trans- lation to work successfully (Disk Manager was unreliable in my experience). Now I am using 386bsd with all translation turned off.
