Having recently had someone bring me 3 of these to build systems with
that all turned up seriously damaged I suspect you have a bad drive here.

Try to run a low level veryify on it, oopsss... ncr doesn't come
with a ``verify'' tool, well, do a low level format using SCSIFMT.EXE.

I suspect you'll find a drive with 1000's of bad blocks on it and
that likes to spin down repeadly.


NOTE TO ALL OTHERS::  BE WARRY, there has been a product dump of IBM
2G DORS drives into the grey market, the ones I looked at had been
physically damaged (broken scsi connectors) and had 100's if not
1000's of bad sectors on them.  These drives are going at prices that
look to good to be true ($350 and below), and it IS TOO GOOD TO BE TRUE.


[Messages deleted, but that was the first messages I got before I started
to investigate the integritty of the drive itself, I could here the drive
spin down just before a burst of errors occured :-(]
