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?

Is this a machine that you've built recently?

Several things to look at:

1. Check the cable connections, take them off one at a time and look inside for bent pins etc.
2. Check the termination of the cable.
   i. if the cable has a terminator on it, check it's connected properly, if possible try a different one.
   ii. if a drive is set to be the terminator, check only one drive is set-up this way.
3. Check you are using the right kind of cable, they are rated accordingly ie 40/80/160 etc.
4. Check the cable for damage. They have lots of twisted pairs of wires, very easy to damage them. Try a new/different one if you can.

You gave very good suggestions, however they didn't help my problem. I think ultimately they are just incompatible with my combination of hardware. Mwave.com actually offered to take them back, so we're sending them back and trying to get more like the IBM drives we know work in our server. Thanks
