sounds like it its corrupted. Not much windows will be able to do if it wont let you open it that is about it from that side. Something I would try is seeing if it will open under a linux partition. If you go to Download - Linux Mint you can download it to a bootable CD and then run it with out installing it. It is worth a shot to see if it will open it. If it does open it just copy it to another drive and then reformat that one. The only other option that i know of is to send it to a professional data retrieval person. VERY expensive so guess it depends on what the data is worth to you.

There are a few programs like Recuva that will recover any data it can find. Whether they work for you or not probably depends on the condition of the drive. It is free. so worth a try.

I think your disk is gone (out of service). You can try user permission or clean disk command. Clean disk will erase your data.
