I recently put together a new system using an Asus P5E and a new Seagate 7200.11 750GB hard drive. The motherboard is SATA 3.0 Gb/s specification and the drive is too. I noticed the jumper on the back of the drive is set to limit to 1.5 Gb/s. This may be a stupid question, but I assume I can remove the jumper so the drive will operate a 3.0 spec, right? It seems odd that the drive would be set to 1.5 "out of the box" so to speak. The seagate manual says something about a "host adapter that supports autonegotiation". What is that? Are there any other settings I need to worry about? Any bios adjustments?

Thanks
 
As I understand it, that jumper is there to ensure compatibility with older versions of the SATA interface (though ideally they are compatible with newer drives). You should be safe to remove the jumper.
 
I pulled the jumper on my new 500 gig 7200.11, and saw no change in the sustained read tests in HD Tune, but the Burst mode almost doubled in SATA II mode.

Not sure what that would translate into in the real world, but every bit helps.
