Answer 1

In windows you need to access the raw device identifier as a file. It should work if you pass in the file "\\.\c:", you are using the device UNC name \.\c: (\. means this machine).

For Vista and later I don't think it will work correctly as there are mechanisms in place to prevent raw access to the disk for anything other than device drivers (don't quote me on that)
