I just bought an mc-80 and installed an IDE Zip drive instead of the SCSI one in the optional empty bay. I have been having problems sometimes writing to the zip even though I can save files to the floppy. The mc-80 detects the ZIP and I can read files from the ZIP, the display shows "incorrect disk" or locks up on me. Does anyone out there know about the jumper settings on the ZIP, etc. or why it wouldn't work properly? Please help ASAP.
