Jumpers on Seagate Sata drive

Was reading chapter 3.2 here:

Its a little ambiguous in that if u do not touch the jumper and leave it at 1.5Gb/s (Sata 1 I believe), will "autonegotiation" set it to 3Gb/s regardless? I would have set it immediately to 3Gb/s but it means removing (and probably losing) the jumper altogether. IIRC my previous drives u just moved the jumper from pin 1-2 to pin3-4, but it does not give this option (even though there are 4 pins just like other drives).

I wanted to ask if there was any place where I could check the current speed within windows xp? I didnt notice anything in the device manager, or should I be looking under administrative tools?

Ive posted in the "post your benchmarks" thread but I meant something simple which tells you the transfer rate that the drive is set to. It used to be in the device manager for PATA drives. If there isnt any setting/info, no biggie. This limit might explain why my Maxtor 250Gb 16Mb has a burst rate of 155Mb/s i.e. hit the cap.

Ive hung the jumper off 1 pin as suggested. I tried to check the speeds of the hard drives, in the device manager under IDE ATA/ATAPI controllers but couldnt really match anything up. Ive got 1 device at UDMA 5 (probably my WD120jb), and 2 at UDMA 6, and 1 at UDMA 2 which I presume is my DVD writer.

I was searching through the troubleshooter for a reason I couldnt see my drive, when the 2nd time of entering the "disk management" part of "administrative tools> computer management"; I didnt cancel the prompt to initialize a disk.

I cant remember using this before but its initialized my disk and set 1 maximum size partition and its formatting my drive. However if I wasnt familiar with the administrative tools Id be stumped. IIRC all I had to do last time was click the disk in explorer's view and format it.

Its a bit tight now in the lower compartment of my P180 with 4 hard drives and wires about 2 inches away from a fan they mustn't foul. A good thing is that the p180 seems to keep my drives at the very minimum of temperature samples as in speedfan's database.
