Explanation

A loud, repetitive clicking sound from a RAID array is the classic symptom of a hard drive experiencing the 'click of death.' This occurs when the drive's read/write heads repeatedly fail to find their calibration position and reset, producing an audible click each time. It is a strong indicator of imminent or current hard drive mechanical failure. Power supplies hum or whine when failing; audio adapters and RAID controllers produce no clicking sounds.
