It's very hard to decide what UseNet articles you can believe.  Some
things that I've believed have turned out to be false, and some of
the most outlandish things have turned out to be true.  If it weren't
for the fact that we are about to place an order for 100 of the Quantum
LPS52's, I would have ignored postings about problems with them as
being outlandish.

However, I spent most of yesterday formatting and loading various
drivers onto an LPS52, just to watch them crash and burn under 6.0.7.
(How?  Among the bombs I remember were "Coprocessor not Installed", and
Stack and Heap Collision".)  I used an SE, and a Classic, with drivers
from Unimac, Questronex, and a few that I borrowed just for the
experiment.  Frankly, I didn't isolate the problem enough to be able to
point my finger at anyone.  The 6.0.7 that I loaded on the LPS52 had
about 30 inits in it, but it all works well on the Quantum P40, and it
seems to work on the LPS52 with 6.0.5.

Is that clear?  The older Quantum drives are solid under any Apple
software, and the LPS52 seems to work under older system software.

When I reached Quantum's tech support, they were kind of nodding their
heads towards Apple, indicating that Apple goofed up.  However, with
System 7 all but out the door, Apple isn't interested in putting out a
6.08....

I didn't call Apple to get their view of the problem.

Quantum said that they are testing new firmware to get rid of the
problem. So, I called Marshall Industries (our Quantum supplier), and
said that the 100 drive order is on hold.  I believe that Marshall will
attempt to get me the new firmware as soon as possible to try out.

Wierd.  Outlandish, eh?  Time to look at the Maxtor 7040s, I guess.
