About 70% of beeping drives turn out to be a power problem in the logic board starving the hard drive of precious energy needed to make the platters spin.  Because of this power starvation the platters cannot spin but the voice coil which moves the read write heads is slightly energized enough to make it vibrate like a tuning fork creating the beeping sound you hear  This can usually be repaired and the drive sent home running with our level 2 recovery.

The other 30% turn out to be the worst case scenario level 3 recovery because the bearings that spin the platters has seized and must be replaced at least temporarily so that the drive's data can be extracted. Although difficult, in the hands of our skilled technician the recovery rates on these situations is great.
