Question: Soooooo, this is very odd, my system just froze and I had to manually reset it, upon booting up I checked my HDD in case some more sectors had become corrupted.
(Before everyone says it’s a bad drive, it’s not as far as I can tell)
The drive has had 1584 uncorrectable sectors for ages, a year or so, I’ve not bothered to replace it because it’s not the primary drive, it just stores all the stuff I can’t fit on my SSD.
Anyway, after this crash, I checked it again, and magically it now has 0 uncorrectable sectors, I can’t understand how this can happen, a if a sector is marked as uncorrectable, how can it be corrected.

My only assumption is that the count overflowed the SMART counter?

Answer:Whether that Uncorrectable number is 0, or EleventyBillion…treat all storage devices as if they might die in the next 0.25 sec.

Plan accordingly.
