We have several PS/2 Model 60's originally with 44Mb hard drives. The technical reference says that these are "MODIFIED MFM" type hard drives. We plan to add a second drive in the open bay and/or swap out the 44Mb for a larger drive. My questions - Will a standard MFM type drive be OK or does the "MODIFIED MFM" mean something like RLL???? Has anyone done this or something like it with third party drives?? Any help/pointers will be appreciated. -- Chuck Bennett INTERNET: uchuck@med.unc.edu Medical Sciences Teaching Labs BITNET: uchuck@unc CB# 7520 University of NC PHONE: 919-966-1134(w) Chapel Hill, NC 27599-7520

I'm 99% sure that by modified MFM they are talking about the fact that the drive controller is part of the drive, and not seperate. I've been looking for Hard Drives for my 55sx, and the only company I've seen so far that makes them (besides IBM) is Micropolis. Your best bet is probably a SCSI controller and a SCSI board.

[...] Wrong. The model 60-041 has a MFM controller card and it is definately not part of the drive.
