I would like to add an ultra wide scsi drive. Can I just use an > adapter? The UW drive can even be used on a 2940, but it then (obviously) reverts to narrow SCSI. And non-Ultra. Not what you want probably, but it can be done (using suitable cables/adapters). SCSI negotiates speed and buswidth. An Ultra WIde capable adapter is obviously the way to go if you want to take advantage of your UW drive.. > I have been looking at adapters and am a bit confused. Do ultra wide > drives have a male or female connector? Normally they have 68pin high-density female on the drive. You could also have SCA, this means everything (including the power) goes over one connector. It would really help if you reveal what kind of drive you have...
