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?

Unpack it and run it as root (or sudo). It will translate all

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

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.
Thanks for writing,
