HDD not reognised by mobo? Makes odd sound.

Specs: Windows Server 2003 SP2, 3.4ghz/4gb
I just got a new mobo (ASUS M4A87TD EVO), along with it a new processor and RAM, but I kept everything else from my old system. I recently got a Samsung Spinpoint 1TB hard disc for the old system (HD103SJ), which has been working fine on my older motherboard (ASUS M2N32-SLI Deluxe).

After plugging everything in, I start the computer up with the intent on formatting the hard disc. However, though I can hear it spin up, and the BIOS doesn't beep or anything, then I hear the hard disc making this odd noise. A sort of "click click bonk" sound that repeats several times until it eventually stops.

The BIOS in the mean time fails to recognise the drive at all. It is a SATA 3Gb/s drive and only has SATA connectors, I've got it plugged into the SATA 1 port on the mobo. When looking at the main BIOS screen though it shows SATA 1 port as having no detected devices.

Is it something to do with the fact the new mobo uses SATA "6Gb/s"? The Hard Drive only makes the "click click bonk" sound when the SATA 6Gb/s cable is plugged into it.

I would be inclined to dig out the old SATA cable I just buried in a draw to see if it'll work, but my DVD drive is also SATAII capable, and connected to SATA 2 port with the provided 6Gb/s compatible cables, and that is detected and works fine.

A couple of suggestions come to mind. First is to make sure there are no sharp folds in the SATA data cable. Next, verify your hard drive is not using a throttling jumper to make the drive operate at SATA I (1.5GB) speeds. Your old board may have required that jumper setting.

I have no experience with any board that has SATA III connectors so I can't advise further concerning SATA III cables.

Of course, it could just be coincidence that your old drive is dieing at this time.

Have you verified the hard drive is NOT being configured by the BIOS by watching the POST screens? Also verify that the SATA port in question is enabled in the BIOS screens.

"The Hard Drive only makes the "click click bonk" sound when the SATA 6Gb/s cable is plugged into it."

To clarify the above statement, when the power cable is connected but no data cable connected the drive spins up but doesn't make those noises? Is the computer attempting to boot to that hard drive?

Thanks for the reply. I've just found out what the problem was, all be it by chance; turns out you weren't on the wrong track when saying about the 1.5gb/s jumper, although that wasn't the problem it was relating to the speed. Seems like the auto setting doesn't work, or doesn't work with this HDD at least (even though it works with the DVD Drive... Also a Samsung).

I found a recent update for the BIOS, so I applied it and then noticed a new option under the configurations for SATA to change the speed from automatic to 3Gb/s. The HDD no longer makes the odd sound and is recognised.

Glad you sorted it out.
