Keywords: Does DEC use some odd proprietary controller query scheme? Message-ID: <1990Jun2.213812.13909@spock.UUCP> Date: 2 Jun 90 21:38:12 GMT Reply-To: lancelot@spock.UUCP (Thor Lancelot Simon) Organization: Choate Rosemary Hall, Wallingford CT Lines: 30 I have an overabundance of DEC RZ23 105-meg drives which are intended to go in a few DecStations that won't arrive for a while. (Please keep in mind that as far as warranty goes, this article is altogether hypothetical.) They look a bit like Quantum 105S, and I figured that they probably were, with the firmware changed so that they report manufacturer DEC, drive type RZ23. However, upon replacing the Q80 in my Amiga HD box with one of these, a 'Drive Scan' from my SCSI format&tools package didn't show up. Didn't even flash the drive light, like it does on everything else I've hooked up to it. I know one can hook up standard SCSI drives (tapes, scanners, and CDROMS as well, though we haven't tried to write drivers yet) to a DECStation, and it will pick them up if you do a 'scsi pb' (drive scan) from the boot prompt, but do the DEC drives have some abnormal query format only understood by other DEC products? If so, could I modify my amiga software to speak it, or does it have to be done at the hardware level (pull a line low or some such oddity)? Just for reference, my Amiga setup is an A500 with a Xetec Fasttrak controller. I have checked all the cables involved, and my controller can talk to just about anything else I hook up to it, except the RZ23s in question. I'm using the utilities that came with the controller, one called 'SCSI Tools', and one called 'Partitions'. The light on the RZ23 does flash a few times when I power up my Amiga, but only then. ******************************************************************************* *Thor Simon * Okay, just a little pin-prick...There'll be no more-* *lancelot@spock.UUCP * Aieeeeaaaugh!-but you may feel a little _sick_. * *uunet!hsi!yale!lancelot* ---Pink Floyd *
