GS and Toshiba CD-ROM XM-520?

[Scarletdown <SecretaryBird@SoftHome.net>]

I just recently picked up a nice little external SCSI CD-ROM drive, a
Toshiba XM-520.  Will this work on a GS?  My GS is a ROM 3 with 8MB of
RAM and a RAMFast SCSI card and running GSOS 6.somethingorother.

What do I need to do to get her to recognize the CD-ROM drive?

Also (now that I've posted an Apple II related question, I'm going to
tack on a Mac-related one here since I'm not currently subscribed to
any Mac newsgroups...)

I have been trying to test this Toshiba CD-ROM on a Performa 405
before trying it out on the GS.  When I run SCSI Probe, the drive is
detected with a SCSI ID of 6.  However, I can't seem to get System 7.5
to mount the drive.  I also tried it on a Mac IIVX.  There, it was
also detected at ID 6, whilst the internal CD-ROM drive was detected
as SCSI ID 3.  The internal mounts fine, but like on the Performa, I
am unable to get the external to mount.  At least, I'm assuming it is
unmounted, as Apple Audio CD Player only shows SCSI ID 3 as available.

Any hints on how to get this drive to work?

Thanks.
