Yup. That's because Sun jumped on the quarter inch cartridge (QIC) bandwagon early, so Sun QIC tapes use the older QIC-10 on-tape format rather than QIC-24. Some QIC-24 tape drives have a QIC-10 compatibility mode that you can set from software, often through the SCSI "mode select" sickness. Other drives can be physically jumpered (yech!). Still other drives have no QIC-10 compatibility and you are up the Ganges without an air freshener. This is probably a FAQ in the comp.tape.qic.lossage newsgroup, if such exists. Grep your tape drive manual for "QIC-10". Good luck. yr obdnt svnt, mjl -- Michael J.
