I friend of mine is putting a CMI hard drive into his AT Compatable.
The CMI drive is a CM6426 with 4 heads and 640 cylinders. Does anyone
know what drive type this would be?
Thanks
Peter

Does anyone This isn't the answer you're looking for, BUT.... CMI had muchos problemas with the early 6426 and 6440 drives. I would be wary of using one in a machine that data that your friend can't afford to lose. -- Peter Holsberg UUCP: {rutgers!}princeton!mccc!pjh Technology Division CompuServe: 70240,334 Mercer College GEnie: PJHOLSBERG Trenton, NJ 08690 Voice: 1-609-586-4800

Some people consider this a definative source of information! Type 3 drives (on standard AT BIOS proms) have 6 heads and correspond to the CMI 6640 drives among others (6 -6000 series drive 6 -head count 40 -rounded off unformatted capacity) not the 6426 (6 -6000 series drive 4 -head count 26 -rounded off unformatted capacity) that IBM sold with the original AT 20Mb config. The CMI 6426 is best approximated by drive type 2. -- Gerald Lotto - Harvard Chemistry Dept. UUCP: {seismo,harpo,ihnp4,linus,allegra,ut-sally}!harvard!lotto ARPA: lotto@harvard.harvard.edu

Hello, The CMI-6426 and the CMI-3426 are both 20 Megabyte units, and in an AT the drive type would be 2. This is the same drive that IBM originally used in the AT computer, but they had a lot of problems with them. So select type 2 and you should have no problems. Be advised that the type 2 drive will only format 615 cylinders, but there is no other choice... Sincearly, Howard Leadmon cp1!sarin!wb3ffv!howardl (301)-335-2206
