Has anyone had any experience with this drive? I would like to place
this drive on a SCSI controller that already has a tape drive and a
100 Meg hard drive on it. I have heard rumours that this drive does
not like being on a SCSI bus with any other devices. Can anyone
confirm/dispel this rumour? Are there any other items of note I
might be interested in?
We will be attaching the drive to an Amiga 2500UX running SysVr4.

Can anyone >confirm/dispel this rumour? The one I had worked fine with other devices on the bus. In my system I had an Archive streamer, Micropolis 1375 disk and a Manta floppycontroller. >Are there any other items of note I might be interested in? I noticed that after an SCSI-bus reset the 4380 is able to accept commands sent to it, but they are ignored for a certain time (apparently while the drive is handling its own reset). You don't get an error from the drive, it just does nothing. This means that drivers without timeouts may hang. I did not have time to find out how this is caused, but as a quick-and-dirty fix I just added a delay of several seconds in my driver to get it to work. The behaviour of the 4380 is different from the Micropolis disks, which do not ignore commands while being reset. Another issue which makes life difficult for vendors saying that they sell SCSI-drivers (because they have never tested their drivers with all available SCSI-disks). So much for 'standards' :-( Hope this helps. Rob. hulsebos@ine.philips.nl

Up to now theese drives work fantastic.
One thing that should me mentioned:
MAXTOR - drives seems to fail, if you use sync SCSI and have a not
correct terminated SCSI-bus. (Happend several times!)
