I would like to help you. I see you are having problems with the drive itself. So I have an idea. Lets check your drive for errors.
To do this you must:
Open My Computer > Right Click on drive> Click properties
Then Click the Tools Tab > Click Check Now (under error checking).
Make sure "Automatically fix file system errors” and “Scan for and attempt recovery of bad sectors" are checked.
Hope this helps! :-)
