Constant spin up and down loop

I have a WD800bb drive.Windows XP

When I power up the computer the HD spins up and down every few seconds. It is not coming out of it.

I swapped the drive to a usb/ide external converter on another computer and it does the same thing.

Any ideas?

sounds like broken to me, sorry mate.
