It's more likely that one of the remaining devices is giving you problems. It's possible that one of your devices doesn't terminate "well", or is picky in some other fashion. For example, I have a machine with an internal SCSI hard drive, an external SCSI hard drive, and two SCSI CD-ROM drives in it. When I had it hooked up so the internal hard drive terminated that end of the chain, I got lots of weird SCSI hangs. It turned out that one of the CD-ROM drives just wasn't happy unless it was allowed to terminate the chain. Turning the termination off on the hard drive, and on for that CD-ROM drive (and switching the cable, of course), made everybody happy. ----------------------------------------------------------------------------- Michael L.
