Can't be done (at least to the best of my knowledge, but I'd love to hear
otherwise). I belive the Sun manuals discuss the subject directly, and the
table below summerizes it. Note also that QIC150 requires a different
types of media when writing "150 Meg" tapes. Be interesting to see what
happens when/if QIC525 become popular ...

                "60 Meg" tapes          "150 Meg" tapes
Tape-Drive      Write   Read		Write  Read
QIC24		Yes	Yes		No	No
QIC150		No	Yes		Yes	Yes

P.S. The QIC150 drives "autosense" the type of tape at read time. That's
the pause and tape noise one first hears.
