The guy that says you need to have a new HDD because he thinks your HDD has been corrupted. You just need to reformat the HDD and you're good to go. But since you list it here, good luck to the winner. If you'll ship the HDD together with this item, the winner will just reformat the unit and its new again. F&W!
Sounds like the HD may have been reformatted, which wipes out whatever OS and programs were on it. Fortunately, I have Windows 7 Ultimate, 8.1 and the tech preview of 10 on disk.
