Seagate U320 connected to Adaptec U160 card, negotiates at "Async" and "Narrow", why?
Posted on 2008-06-20
I have 6 new Seagate Cheetah U320 drives in a Dell Poweredge 2300/500. Backplane connected to Adaptec 2110s SCSI raid controller. I have had an IBM U320 connected with no problems but the card reports any and all of the Seagates as negotiating the slowest possible speed: "Async" and "Narrow". Why? I believe I have the latest firmware on the Adaptec card: 380E and Seagate tech support tells me I have the latest firmware: 0003. What else could be the problem?
