I have a SATA drive, no jumpers, my granddad just bought a 320gig SATAII Baracudda, and it has jumpers, and what it is too do is to force it to run SATA 150. but there are no jumpers to set slave/master as there can be no more than one drive per cable.
I did a bit of studying and found that the jumpers on my JB drive enable (or disable) PM2 which is advanced power management and enable 150MB/s transfer rate.
What's odd is that my 1600JB's came with the PM2 enabled (according to the documentation, not standard) and the 150MB/s disabled which is standard. Go figure.
