Understanding the exit code⚑
Check the manual for the exit code values interpretation. There is a code for understanding the mask.
Debug⚑
Long test won't finish on a external drive⚑
If you are getting Interrupted (host reset) in the selftest log it's probably because you are using an external drive and the OS is stopping it after a while. We need the disk to be active for the host all the time to avoid suspension, to do so we can do:
sudo bash -c 'while true; do smartctl -a /dev/sdb > /dev/null; sleep 60; done'
