[comp.sys.ibm.pc.misc] 1.44M Drive Problem

chung@EE.Surrey.Ac.UK (L N Chung) (09/13/90)

Sorry to ask again, but our news system failed me again.


We installed a 1.44M drive in an *OLD* IBM 6MHz AT. It seem to read and write
the disk ok. But it won't format 720k disk. When we use "format b: /n:9 /t:80"
it just reply with parameter not supported error.

It this something to do IBM's ROM ? We use PC DOS ver 3.3.

Can someone remind me what the problem and best solution was?
