Is there any way to retrieve my files? I took my computer to a local computer store and he looked at it and said that it would cost $200 - $230 to replace the hard drive and it would probably be cheaper to purchase a new computer (I got a Gateway 15.6" 4 GB Memory 500 GB HDD for $259.) I asked the technician at the computer store if he could retrieve my files and he told me probably yes but after he looked at it, he said he couldn't. He said the drives were locked. Is there any way to retrieve them without going to a professional "retrieval" company that would cost "lot" of money?
