SATA Jumper setting

[Collider]

I noticed that SATA drives have a jumper setting limmiting transfer rate to 1.5 GB.

What is that used for ? Why would u want to have your drive run slower ?

There are some older mother boards that won't see sata II drives without the jumper in place. Very few of them have this issue from my understanding, but enough of them that the jumper option is there.

First and foremost, you should try the drive without any jumper at all. If you have issues / problems after that point, then try limiting it to SATA1 / SATA150.

It's for motherboards that support only SATA 1.0 and not SATA 2.0.

It is for locking the tranfer rate to 150 for SATA-150 controllers that lack the autonegotiation feature like my old Via 8237 southbridge (I think the 8237A negotiates) mobo. SATA 2 drives will play dead when connected to it. I RMAd a perfectly good Hitachi drive due to that new behavior. If your controller can negotiate, then (as FMC wrote) you won't need the jumper as the downshift will happen automatically. But if your drive plays dead, then add the jumper and try again.
