I noticed in the gnome-disk-utility that an old HDD I'm not using much anymore was colored red. Clicking it it said the disk was likely to fail soon. smartctl -a output showed the overall health assessment of this disk was FAILED, seemingly because it had a really high rate of read errors.

This seemed a very sudden onset for such bad-looking number, so I decided to do a SMART test on this drive to get more information about the failure (and also for the experience of running a SMART test, which I've never done before) -

sudo smartctl -t short /dev/sdb
But when I re-ran sudo smartctl -a /dev/sdb after the test completed, the read error rate is now zero and the disk thinks it's totally fine?

What to make of this?
Can I trust this disk going forward? (I don't currently have any data on this disk.)
