Hi Netfolks,

A friend of mine dropped in the other day with a non-working system...  It
appears that his hard drive is not working.

Symptom:

The drive spins up fine at power up, but shuts down after a few minutes.

If the system boots before the motor shuts down, there is a tendency for
information to be read, but _very_ slowly, and with (apparently) lots
of retries and failures.

The drive's indicator light blinks:  # ! # #  (# "long", ! "short")
I am assuming this is some kind of diagnostic code.  Can anyone help?

Thanks a bunch!

An associate says he remembers seeing articles that described how to write

to a certain register which hardware disabled writes to the drive.  This
mode could only be undone by warm boot or power off (not sure which).
Anyone know more specifics about how to do this?

Does anyone know what software will drive the Mountain TD-8500
tape drive?  It's a QIC-80 compatible and runs as a slave off
your IDE controller giving you up to 10 Megs a minute backup time
(or at least that's what they claim).  

The software they supply does NOT back up Mac files across a 
network, so I've been looking for other packages that will.  I
have a copy of ARCserve/Solo from Cheyenne, which I'd heard good
things about, but the Cheyenne techies didn't have the first
clue whether their software would run this drive.  Anyone have
experience?  What about Palindrome?  PCTools?  What software WILL
back up Mac files?

TIA!

I've been using the Crystal Fonts driver with my ATI Ultra Pro LB on 
a Gateway 4DX2-66V (Micronics VL-Bus) and have had no problems, except that
when I open a DOS window for the first time I get garbage at the top of

that part of the screen -- say, by moving a window over top of it and then
moving the window back to its original location.)

I though so too but it locked my machine up consistantly when it tried to

fine.  When they sent the updated version it worked fine with Windows setup

Also I need to mention that I'm using Omnipage Pro as another post pointed

 And then I just recently sent a computer UPS and had all sorts of things

of sockets, a toggle switch in the back of an external drive box fell apart,
etc.

 And I had that computer wrapped up tight in foam, bubble wrap, and in a
box using four ply corrugated cardboard.  Obviously UPS has the Samsonite
gorilla working for them...

 I've worked in both shipping and receiving.  I've seen a lot of things
happen.

 One thing, when I was working in a shipping department nearly every one
of our customers refused to receive from UPS if RPS served their area.
UPS has a bad repuation for damage and loss of packages.

 Unfortunately RPS is only common on the east coast right now.

I have just purchased an HP Laserjet IIIP for use with my IBM compatible

print" (by pressing shift-printscreen).  
	Actually, I do get a text screen print, but following the print pages
and pages of "escape" sequences are printed, with no apparent end (I turn
the printer off to stop it).  When I try to print screen with graphics on the
screen I get a page of excape characters, followed by another set of pages
and pages of escape characters.  I have remembered the GRAPHICS command,
prior to attempting to print screen.
	Some background info'.  My PC is actually an ITT XTRA Professional
Series (AT compatible), 10 MHz 286 (I think), with 1.4MB memory and a 40 MB
hard disk.  Prior to purchasing the HP laser jet IIIp I had an IBM proprinter
which did printscreens perfectly well.
	If anyone out there has any ideas, please reply directly to me, as I

I am in the market for a CDROM drive to attach to my Adaptec 1542B SCSI
controller. I have borrowed and used a Toshiba XM3301, and it works well,
even in OS/2. I am not sure if I want to buy my own Toshiba, or get something
else. I suppose something that is MPC compatible would be nice.

I have a price list from a local company that has a Texel drive. Does anyone
know anything about these drives? They have a couple models, all MPC ready.
The cheaper one is 340ms access, and 150Kb/sec transfer. The better one is
265ms access and 300Kb/sec transfer. This better model is priced at $449.
This sounds fairly reasonable, given that it is dual-speed with fast transfer
rate. It claims to be fully SCSI compatible, and the company claims to have
Adaptec drivers, although the ASW-410 package (Adaptec CDROM driver kit)
doesn't list this brand of drive. Is this their own mechanism, or a mechanism
from a more well know manufacturer (like NEC, or Sony, etc) just re-packaged?

I have seen the XM3301 priced at $399, but I think it is only 150kb/sec
transfer, and I would like to get the newer faster drives if it is only a
few $$ more.

Any opinions are welcome.

Sean,

Although not familiar with your hardware, we had problems with a 386sx when
we added extra memory. The machine came with 1x9 SIMMS and we added 1x3 SIMMS.
The new SIMMS worked for a while, then started to show parity errors once they
warmed up. Unfortunately the disk cacheing was trying to use this memory. The
result: cross linked files, a corrupted FAT on the disk, and many hours of
work to fix things up :-(. Can you swap the SIMMS over for 1x9s? Just a thought.

Cheers,
Paul Heuer. (pzh@aeg.dsto.gov.au)
