I bought a powered Sata-USB adaptor and again followed this writeup to move everything to the new drive: How to Make Raspberry Pi 3 Boot From USB
But I run into trouble as the system becomes unresponsive after about an hour.
Last time I couldn´t even log in via Putty. Now it let me log in and it gave me these errors.

As I´m a noob I have a clue about the issue, but not about the solution.
