I did perform the self-test function, the long version that says it will take 10s of minutes. Some of the errors were displayed with red text before the test. It said my drive passed snd after the self test all the red errors showed up as “Old age” in black text, every single one.
I used the GUI program for SMART and the list of issues got marked as “old age”, all of them.
They meant the SMART self-test, not SMART data readout. Those are not meant to be interpreted by laymen and often not even experts.
