Hard drive problem

Given its size, your new drive is most probably sata II. Does your mother board support sata II or just sata I. Consult your motherboard documentation.

Sata II is backward compatible with sata 1 so should still work but at sata I transfer speeds. It reconfigures itself to run at a slower speed via auto detection. However, some motherboards may not support auto detection and you may have to ensure the sata II drive is forced into working at sata I speeds by setting a jumper on the back of the drive. Consult your drive documentation.

Just a thought.

Hi Ferret! The drive has the following information re jumpers on it. 1 & 2 is spread spectrum clocking, 3 & 4 is power up in standby, 5 & 6 enables 1.56gb PHY whatever that is. Are any of these the right ones to slow it down? Jim

If you jumper 5 & 6 you will force your drive into sata I mode, 1.5 GB/sec rather than the default 3.0 GB/sec of sata II

But like I said, check your motherboard first - the sata controller on your motherboard may support sata II, in which case I doubt the drive jumper setting is your problem.

Thanks Ferret. The link works. Now to find how to format the drive. How can I change over C and D drive, just rename them?
