SATA2 Hard Drive Jumper
I recently bought a brand new Dell Dimension 5150. It has a Seagate Barracuda 320GB SATA primary hard drive and I have just added a Seagate Barracuda 320GB SATA2 slave hard drive. On the slave drive there is a jumper that limits the data transfer rate to 1.5 G bits per second (for motherboards that don't support auto-negotiation), or you can remove the jumper for 3.0 G bits per second operation.
My question is what should I set the jumper to, does the Dimension 5150 support auto-negotiation? How can I find out?
