RAW just means that something in the partition went wonky and Windows doesn't know what to do with it.
What I do in these situations, especially if I have data on the drive that I need is grab Download Hiren
and burn it to a CD or install to a different flash drive, and boot the system up using the Mini Linux image. Plug the drive in and see if you can mount it (right click the desktop, choose Mount/Unmount and look for the flash drive) Once you mount it, the OS will prompt you and ask if you want to open the file manager, pick one of the file managers (the first one usually works fine) and see if you can browse the contents of the drive.
If it doesn't work, chances are the drive is toast.
For what it's worth, my aunt has owned several of these - they're trash. She can never keep one for more than a couple of months.
