What happens when you enter ?ds$ from the 8032 prompt? What I do for drives that at least power up is boot a 4040 diagnostic disk on a good drive and then swap the cables to the bad drive and run the drive diagnostic loaded into memory. At least I will get more info as to what's wrong. Do you have a 4040 diagnostic diskette? Bill Message was sent through the cbm-hackers mailing list
