Just recently we have had an influx of unrecoverable Seagate Momentus 2.5″ hard drives. These drives are used in most of the Apple portables from the Macbooks to Macbook Pros and also in laptops from other manufacturers. Ranging from 60-120GB they seem to suffer from some sort of media defect. Most of the problems we see with these drives are head crashes, where the read/write mechanism contacts the disc surface, removing some of the magnetic coating. This damage is not always visible on the top surface of the disc so can be difficult to confirm. If we do see damage then we would not usually attempt any rework, due to the almost instant contamination of the new component. After many failed recovery attempts and much money wasted on replacement mechanisms we decided that we should just inform our customers of the problem before they send us the drive as we have only had one single successful recovery from these drives. I have listed some affected model numbers below for information purposes only. Please be aware that we have no information about how widespread this problem may be. We do only see defective drives in our line of business!
We are still receiving a trickle of these drives in for diagnosis. Unfortunately they are still unrecoverable. There must be loads of people still using these, without any idea of the potential failure that awaits them.
