Actually, reading the NSA hard drive firmware hack a couple days ago rekindled my suspicions about all the MacBook Pro failures a few years back. Apple claimed the hardware was at fault & nothing short of sending off for a pricey, clean-room extraction would get the data back. Much to my clients' relief I recovered all the data from three MBP drives for a lot less than what the 'geniuses' quoted. *It was the HD controller at fault, I managed to get them to mount and read at an extremely slow rate, but in time all was recovered.
