Hardware HDD stopped "accepting" data when installing (or moving) games

[CalledPex]

Hello. I have this problem with my Wii U.

When installing stuff directly to my HDD with Wup Gx2 installer, for the first 2GBs it goes well. Then, the hard drive's LED stops lighting up and the screen turns black. Also, when I install stuff with Wup Gx2 installer to my NAND, it installs correctly.

I'm running Mocha on 5.5.2 Black 32GB Wii U. This also happens when moving or copying stuff on from the NAND to my Toshiba HDD (connected with a Y-Cable) in the system settings.

I get 2 kinds of errors while copying/moving. 150-3031 and 150-3032.

Any help?
