Disappointed that I had lost all of my data files, I started talking to other computer persons about this problem. I took the "un-working" hard drive to a friend at work. We installed the "un-working" hard drive into another working laptop computer. In about 15 minutes, he told me that the OS Windows system was corrupted BUT the hard drive was fine and the data could be recovered. [...] We hooked the "un-working" hard drive to a computer with a LINIX system. Guess What !!! All the data on our "un-working" hard drive was recovered in about 20 minutes.
No refund, of course
