I guess my hard drive is toast. I took it to a repair shop. They told me they couldn't retrieve anything from my hard drive. I'm a little suspicious of them, because they didn't know how to put my DOS-based files back on my computer. (I know, don't ask why I still have some DOS files.) I don't know much about computers, but should I take my hard drive somewhere else, or is it pretty easy to determine if the data is unable to be retrieved?
