[comp.sys.apple] 45MB removable hard disks

SOMCYC@NUSVM.BITNET (Chiang Yao Chye) (03/10/90)

Can anyone give a definitive answer on whether those 45MB removable
hard disks (based on the SyQuest technology) for the Macintosh be
used on the Apple IIGS with a SCSI card?

Presumably, it would work just like another hard disk, but what I
really want to know is if the cartridges can be mounted and unmounted
without rebooting?  For example, will the Finder say 'Please insert the
disk: Cartridge2' when you took it out, just like any floppy disk?
Does the hard disk driver in GS/OS know there is such a thing called
a removable hard disk?

Thanks.

I am not even sure what brand it is that I have access to, but the cartridge
drive I have use of treats the drives just like large floppies.  They have to
be unmounted when removed if you don't want them referred to again.

Hope this answers your question, but I can find out what brand we use if it is
that important.

	I can - they work, but there are some serious quirks. I'm in the
process of writing a review of sorts, and I'll discuss the quirks in it.

	Yes, you can mount and unmount carts in the Finder (it greys the
icons, etc.) and in GS/OS, but, as mentioned, there are some nasty quirks,
and I'll mention those. The SCSI driver does know about removeables - Jason
Harper's DevList program shows the devices as being removeable, for
example. Remember, the //gs supports CD-ROMs, and they're removeable...

	No problem...
