Backward compatible SATA III and jumper cables

post #1 of 4
Thread Starter 
Hi there,

I just bought a Seagate 2TB SATA III backwards compatible hard drive OEM. My motherboard only supports SATA II. Now on the Seagate website it provides instructions to limit my hard drive from 6Gb/s to 3Gb/s by using a jumper, however no jumper was provided when I bought the hard drive.

Regardless, I plugged the hard drive in and it was detected okay, I am formatting it right now via Disk Management. It's going to be a storage device.

So my question is - do I still need to find a jumper to limit my hard drive speed? What are the consequences if I leave it as it is?

And secondly, where on earth do I find one? I don't think they're sold individually?

Also, the hard drive didn't come with screws either (it's currently balanced on a shoe) - any tips on where I can scavenge some of those? lol

I always thought OEM just meant it came without cables/manuals but I guess I was wrong.

Many thanks,
Flameenix

ALL sata 3 devices are backward compatible with SATA 2. you shouldn't have to do anything special, just plug it in. as for the screws, you can get them from a hardware store, just take one from another drive and match it up when you get to the store.

Oh I didn't know that. So then why are there 4 pins on the hard drive then for a jumper?

Thanks for the help. I'll get the screws sorted tomorrow.

Older SATA II drives have jumper pins too, they limit the speed by half when jumped. I was always under the impression that some motherboards might not work with them at full speed, however. I've never dealt with that before though. In your case, it apears that everything is working fine if your drive is being recongized and used, so I don't know if I would worry about it.

If you are looking to get jumpers, then you can always look to places like ebay or online. you may end up having to buy a pack of 12 or 24, etc. It would be almost impossible just to get one jumper smile.gif You could also check a local computer store if there is one in your area, they may have extra jumpers on hand that they would be willing to give/sell to you. Be careful though, there are different sizes of jumpers out there. Try to make sure you get one that fits the distance between the jumper pins on your drive.
