Hello Phil, error 85 means: you have reached the hard disk time-out limit... the hard disk hasn't answered within a given time- probably the system track, boot secor is bad . You need a fresh low level format.- or a new drive if the number of bad blocks exceeds 30 counts.

Do you have a freezing spray to cool down the chips to locate the error on the controller? I have the same problems- no way to get these chips today- only if you rip the chips from an Amiga 1000 sidecar (PC-XT hardware expansion box) or form an old Atari ST MFM hard disk controller. > The SUN REM drive uses a Kalok KL320 (20mb) MFM drive.

I'm testing these MFM hard disks on my old 80486 IBM AT with an Adaptec ACB 2310 MFM controller card. But: You have to know how to perform a low level format on the SUN controller first! > Or even better, does an adaptor exist for MFM to IDE?
