Yet another attempted data recovery was thwarted today by the dreaded head crash. We have seen possible head problems with these drives and were not surprised when the drive didn’t come ready and identify. This particular drive, an ST96812AS from a MacBook Pro was giving off some interesting sound effects to say the least. Expecting the usual failed read/write head we took it into the cleanroom and removed the cover. This drive had clearly had a head crash. Not only was a large area of magnetic media forcefully gouged off by a stray head but there was also a faint scrape towards the outer edge. We have seen this minor damage on these drives before and still been able to recover some data, although the read/write heads don’t tend to last very long. Data recovery after a head crash like this one is impossible and will be a waste of donor parts and spare drives.
