Never knew that. Might explain why before I got this custom drive some RVT-R's showed as blank DVD-R's in normal DVD drives. My next task is to crack Wii U CAT-R dumping lol. Possibly getting some CAT-R Sonic beta's in the coming months. Going to see if a retail Wii U drive can be hacked to connect to a PC first, Then I'm going to try and grab the CAT-R firmware and reflash the drive or something.
Good luck with CAT-R dumping. I have no idea how that stuff works. (I do know that it's SATA, but it probably has some sort of encryption.) If you can get a CAT-R unit, you might be able to hack it and run wudump: https://gbatemp.net/threads/wudump-dump-raw-images-from-a-wiiu-game-disc.451736/
Heh yeah I need luck. Only thing I know is it's Blu Ray based tech. (25GB images). Read about the SATA bit a few days back so going to see if an adaptor can be made to connect to a PC.
