Actually I may have been premature in blaming your problem on QIC-10/24 incompatibilities, since you say other UNIX machines have no problem reading your Sun tapes. You might try writing a tape on a non-Sun and seeing if your Sun can read it. It's possible that your other vendors have drives and/or driver software that can read either QIC-10 or QIC-24. If your Sun cannot read a known QIC-24 tape, then it is possible that your SCO/Mountain setup may need additional driver support or controller re-jumpering to read the QIC-10 format that your Sun is writing (as I stated in the previous article).
