It would be the same jumper that would be used on a motherboard or other computer cards.
I have a huge drawer full and if you can't find one, just PM me an address and I'll mail you some.
Thanks for the offer (most generous
) but I just pulled out the machine's current hard drive and saw the jumper you mentioned. I've learnt something already!
Also, I don't know if it means anything, but I noticed the two SATA connectors on the motherboard are labelled "SATA 1" and "SATA 2" (one is black, the other is white) - could this mean it'll accept a SATA 2 drive without the jumper changeover?
