I want to say to everyone that Thomas Kaeding helped me save all the data from a friends hard drive. It was a MyBook Essential 2TB USB3.0, model number wdbacw0020hbk-00. The USB-to-SATA board fried and did not start the disc, nor it got recognized by the computer. I testes with different power supply and USB cable and nothing worked. This board has a Symwave SW6316 chipset which applies hardware encryption of AES-256 to all data. After a few minutes of sending the disc blocks containing the key to Thomas, he was able to point me with the unscrambled key and how to use it in Linux (I used Ubuntu Mate).
This guy deserves to be contracted by WD and receive big money from them. WD should provide a tool, made by this guy, to help all the people solve this problem in the event of a failed external case. This is a well known problem and many people loose invaluable data because of this problem. If this only works in Linux, at least WD should provide a virtual machine made from this guy, so that people can retrieve their data. After that, the drive can be formatted and used without encryption, in a typical USB-to-SATA external case.
Thank you very much Thomas! I hope someone from WD sees this and takes the action of contacting you so that you receive the credit you deserve, and also the monetary compensation.
