AFAIR maximum cable length for IDE on the EFIKA is 0.
Read all attempts to just move the HD failed on a HW level.

USB issues might also be on HW level, but....

I realized that copying many files from Shell works fine, while doing it in Ambient fails.

Not 100% sure why and while it is something I might be able to fix (or at least investigate further), it is just not at the top of my priority.
