I took my old WD Caviar WD1200JD from my old PC running Windows XP through SATA and installed it on my current machine running Windows 7 through SATA.
The drive spins up and clicks and spins down again a few times. When I try to access it, it does the same thing even though I can still access the files on it.
When I plug the drive into a HD caddy using USB, it functions normally without the spin up, click, spin down. When I use eSata on the HD caddy, the spin up, click, spin down noise comes back.
I plugged the hard drive back into my old machine and it works fine without any loud noises. It also passes SMART tests and Extended Test.
Could there be a problem with the WD1200JD with Windows 7 or my motherboard on my current machine not liking the hd? Or is the drive dying? Seems to work fine on my old machine.
