Western Digital WD Caviar 60GB-250GB desktop drives, fail suddenly with clicking, clunking and humming noises. Our research and development engineers have identified that this is caused by firmware damage and linked to excess temperature.
Problem is apparent when the computer fails to restart operating system. Allowing the drive to click, will damage the heads and crash the disk surface, causing serious data loss. Immediately stop the drive and do not re-power. Contact DiskEng for professional advice and data recovery.
