[comp.sys.ibm.pc.hardware] RLL disk formatting problem.

wind@cellar.bae.bellcore.com (Wind Chen) (09/07/90)

If your disk controller is "AT controller", you can NOT use it to support RLL
type disk.  26 sectors are known by controller, not the CMOS.  Without a RLL
controller, you can only get 20MB out of it.

There were people use RLL controller + ST225 and get 30MB capacity.  The track
is on controller.
