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.
