A raspberry pi running 64-bit RasPiOS froze up and failed
to reboot reliably, apparently unable to find the hard disk.

The USB-serial bridge was replaced with a known-good unit,
which allowed repeated successful reboots. After a long self-test,
sysctl -a reported a raw_read_error_rate that looks rather bad but
nonetheless claims the disk "passed":

I'm somewhat baffled at the wording, can anybody tell if the test actually ran
to completion and the results imply a healthy disk?

Save any important data you have on that disk, then "retire"
it.
If you're interested, HDSentinel has a free utility for Linux:

<https://www.hdsentinel.com/download.php>

Unpack it and run it as root (or sudo). It will translate all
that stuff above to human language.

Website, or hard disk? The disk was bought and set up in September of 2022,
which more-or-less gybes with the 11k hour runtime as it's on 24/7. I wouldn't
normally think of a year-and-change as "old" for a hard disk. Am I mistaken?

What did puzzle me was the substantial Raw_Read_Error_Rate, zero count of
uncorrected errors and zero Current_Pending_Sector figure. One is bad, the
other two seem good, unless I misunderstand the meaning.

hdsentinel-019b.gz is dated 5 March 2021.
Probably not as old as the HD the OP is testing...

PS I use it under Devuan. Works perfectly.

Not quite 8-) Looks like the drive was made in December of 2021.
