[comp.sys.tandy] read only disk drive

nigel@isgtec.UUCP (Nigel Burnett) (12/09/90)

I'm posting this for a friend who has no net access:
-------------------------------------------------------

I moved a hard disk and its controller from an old tandy 1000 to a
tandy 1000SL.  All seemed well at first - I could boot
from it, and look at or run anything that was already there,
but any attempt to write to the disk resulted in a 1 min pause,
then the message "not ready error writing drive".

The SL has a rom drive (normally drive c) and the cpu is an 8086.
The drive is a miniscribe 3650 on a western digital mfm xt controller.
The same problem occurs on an rll controller.

Anyway - with either IRQ2 or IRQ5, the drive is not-formattable on the
1000SL.  If it is formatted on the 1000 or on a PC clone, the drive
comes ready and can be read fine on the PC, the 1000, and the 1000SL.
However, although it can be written on the PC and the 1000, it cannot be 
written by the SL.  I presume the problem is related to the built in
ROM drive which is normally C:.  It migrates to become D: and the hard
drive is recognised as C:.  Now we've got two read-only drives!

I'm sure that if you can shed more light, he'd really appreciate it.

Someone (Scott? - I lost your return path) suggested that it was a grounding
problem.  Well, we grounded everything together very carefully and still
have exactly the same problem.

thanks

Hi, it's me, Scott.  Sorry nothing else worked.  Have you tried the mod
I mentioned?  If the drive is a 25-1032C you are entitled to a free mod
which SHOULD fix the problem.  Just have a store send it to repair and
make sure that they note on the tag that the shop should call you if
there is going to be a charge.  Then, if they call, RAISE HELL.  Call a
district manager if you have too and you'll get it fixed for free, as it
should be.  Mainly, just make sure that the salesperson notes on the tag
that the problem showed up when you moved the drive from a 1000 to a SL.

PS: do you have a non-UUCP address I can reach you at?
