In the middle of the night, my WD WD2000JB started making a clunking noise (like a stepper motor moving about 3 or 4 times). Took the machine to bits, tried different data/power cables as well as without any other drives connected, and the result's the same. Listening more closely, the drive seems to spin up, clunk about 4 times, then spin down (and repeats that). Neither Windows nor an Ubuntu Linux live CD can see the partitions on the drive (though the BIOS detects it, and both show the drive as connected). Any suggestions as to how to get it working (or at least get the data off it) before I RMA? Ta.
