When you opened the drive you voided the warranty. If this was a drive with Smartware the data is hardware encrypted by the board with the USB connector. Raw indicates corruption of some kind. I don’t know what will work now that you partioned it. If the rest of the drive still shows Raw you might have some luck with TestDisk http://www.cgsecurity.org/wiki/TestDisk or EaseUS Data Recovery Wizard http://www.easeus.com/resource/repair-raw-disk.htm A recovery program like Recuva http://www.piriform.com/recuva. might work too.
