Newer Quantum drives need Initiator ID, which the TT TOS will not provide
without a patch (I have a Fireball TM running as the only disk in my TT).

In any case, you have to turn on Initiator ID (in NVRAM setup / HDDRUTIL).
Then, you may either
 - use a different disk as bootdisk to load the driver or
 - patch the TT TOS to use initiator ID.

If you want to use Magic, at least Magic 5 needs the same patch as TOS 3.06
(same code, also).

If you access the disk without initiator ID, it will not respond to any
forther commands until the next SCSI BUS reset, so it may well look as if it
were dead if you have it on a low ID and it is scanned first by an
unmodified TOS.
