Help recovering data from a 3TB Mybook studio

Hi everyone, I had a 3TB Mybook studio drive (one of the ones with firewire 800 and an e-ink display). A few months ago, not knowing about the hardware encryption, I decided to take it apart and put the drive in a new enclosure that supported USB3 since I no longer have a machine with firewire 800 and USB2 is slow. The drive wasn't recognized in the new enclosure and when I tried connecting to the old board again it still didn't work. I got distracted by other problems and didn't come back to trying to recover my data until today, but unfortunately the old board got lost so I can't tell you what kind of chip it had.

running `reallymine getdek` fails after a few minutes with an input/output error so I currently can't get a a dek. I'm attaching the output of `reallymine dumplast` to this post in case that's helpful. Please let me know if theres any additional data I can share to help me get to my data.

Thanks!
