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 :-(] -- Rod Grimes rgrimes@gndrsh.aac.dev.com
