USB3 enough to power 2,5 external HDD?

[Luke]

Auyfan's stable bionic minimal image gives me this when I try to write on the drive. I'll try DietPi next.

Code:

As you can see, it throws a bunch of I/O errors and the system assigns a new letter for the drive next.

Those have the same kernel. Try this build and let me know if you're still getting errors. You can also try switching over to mainline (currently in ayufan's repo thts 5.1)
