[comp.sys.amiga] Problem w/A2000 & A2091?

oovvoo@mixcom.UUCP (Michael W. Shawaluk) (11/12/90)

First of all, let me say that I'm not absolutely positive that the above
hardware combination is the source of my problems, but I'll more completely
describe my system in a moment, and hopefully someone else out there can
help me (or at least point me in the proper direction):

The symptom:  I will be unZooing a particular file, and I will get CRC
errors on a particular member (or members) of that file.  If I try the same
extraction command again, the same file member(s) will fail.  Using ZOO 2.00
or 2.01 yields the same results.  Now, if I copy the offending .ZOO file to
RAM: & try it again, it works fine!  It doesn't seem to matter whether the
destination of the extraction is RAM: or my harddrive; I've tried both, and
I still get the errors, IF the .ZOO file is on my harddrive.

Now, let me outline my hardware & software setup:  A relatively new 2000
(purchased just BEFORE the 3000 was announced, grrrrr... :-), with the 1 meg
Agnus, 2091, Quantum 40 meg included, and a Quantum 80 meg added.  I've also
populated the 2091 with the extra 2 meg of RAM.  No other peripherals inside
the 2000.  As for software, I am running 1.3.2, with the latest ARexx,
ConMan, FComp, WShell.  To be honest, I haven't done much about the problem,
because (a) the previously described workaround had been doing the trick for
me, and (b) I originally thought that I had defective .ZOO files, and 
re-downloading them "fixed" the problem; maybe because they went to a 
different part of the disk?).  Upon further reflection, I am concerned that
my hard disk may become corrupted (or maybe already is), although I haven't
observed any other programs misbehaving in this manner.

So my questions are:

1.  Could this be ZOO's fault?  If so, how?

2.  If it's a hardware problem, what's broken?

3.  If it's a software problem (other than ZOO), has anyone else seen it?

Or, am I wrong on all counts, and is my system just infested by a ratwere?
(sorry, my son's been playing quite a bit of nethack lately; maybe a few
blessed scrolls would help :-)

Thanks in advance, and please accept my apologies if this one's already been
discussed before.

Ok, I have a 2500/30 w/40meg quantum; flickerfixer; 2286 --
Now, if I had another external SCSI and I want it to work correctly,
i.e. not turning of reselection and whatever tricks there are - all
that I have to do is pay $20-$30 for the upgraded chip for my 
A2091 controller or will it still not work quite normally - i.e.
multitask and everything.

Thanks - I appreciate the time it takes to respond.
