Here at work, we have a number of Mac Plus machines. Some
are equipped with IOMega Bernoulli Box 10+10 hard floppies,
and one (mine) has an Apple Hard Disk 20SC.

Lately, we've been having problems with Bernoulli Box cartridges 
getting garbled -- the Finder says the disk is damages,
IOMega Tools displays a garbled disk name, Disk First Aid says there's
something wrong with the disk, tries to repair it, says it's done,
and makes no difference at all. This problem seems independent of
the Bernoulli Box, because we switched Bernoulli Boxes and still had
the same problem. In the hopes that we might find something
wrong with the Mac Plus involved, I am now using that Mac Plus
with a Bernoulli Box, and my Hard Disk 20SC. 

Now, I find that strange things are happening. To wit, I can't have
both the Bernoulli Box and the Apple Hard Disk mounted at the
same time! If I mount the Bernoulli cartridge, when I quit
to the Finder, the Apple drve just sits there and
spins on and on and on.... I end up having to
reboot, and then I can work, as long as I don't
mount that Bernoulli cartridge.

It seems as though there's some strange interaction between the
Mac Plus, Bernoulli Box, and Apple Hard Disk 20 SC. I understand
that someone else in my group's had similar problems trying
to use a Bernoulli Box with a LoDown hard drive, while yet another
person has successfully used the Bernoulli Box with a SERIAL
Apple Hard Disk 20 (the one that connects to the drive port). 
This indicates to me that it's purely a SCSI related problem.

For the record, here's my system:

	Macintosh Plus (1mb)
	Apple Hard Disk 20SC (configured with Apple HD SC Setup version 1.1)
	IOMega Bernoulli Box

	System 4.0
	Finder 5.4

	The bernoulli Box is SCSI address 5, and the HD 20SC is SCSI 4,
so I know there's no address conflict.
