MFM Hard Disk Reader/Emulator This page has information on the MFM hard disk reader and emulator I have been working on. The unit is intended to read MFM hard drives for archiving and to emulate one or two MFM hard drives to replace failing MFM drives. The image read from a real hard drive can be used for the emulation. In theory the unit can emulate any MFM hard drive. In practice there are enough variations in how controllers use the drives that software changes have been needed to make it work with some systems. You will need to use a command line to operate the unit for reading disks and to configure it for emulating disks. It should be able to read and save the raw transition data from most any hard drive using the ST506/ST412 interface.
