You didn't say whether you had a terminator installed, or if your last SCSI= =20 device was properly terminated. You need the end of the SCSI chain= terminated. This controller is very touchy, in my experience. It requires a=20 high-quality cable, clean connectors of good quality, and good, working=20 active terminator or proper termination set on the last device in your SCSI= =20 chain. This is usually done with jumpers. I didn't have much success also until I separated narrow and wide SCSI=20 devices, putting them on different channels. The narrow devices, a Zip=20 drive and a SCSI CD-R drive, are on channel B together, with the CD-R drive= =20 terminating the channel. The two wide SCSI disks are on the A channel; the= =20 second of two disks is terminated. When I disconnect the external SCSI Zip drive, I replace its connector with= =20 an active terminator.
