Yet, running smartctl -x shows a few pre-failure
values. To wit:
1 Raw_Read_Error_Rate POSR-- 117 099 006 - 131606848
5 Reallocated_Sector_Ct PO--CK 100 100 036 - 3

No, nothing there is indicating a risk of imminent failure. That
"Pre-fail" label is just telling you what it would mean if there were
something other than "-" in the "WHEN_FAILED" column. The only thing
there that is at all indicative of something bad happening is the three
reallocated sectors, and that's only a problem if that number continues
to grow. (Vibration or electrical disturbances can cause a sector or two
to get marked as bad, and that doesn't mean that the drive is in danger
of catastrophic failure.) An attribute of interest that you didn't
report is #197, "Current Pending Sector". That would indicate sectors
that are currently unreadable and will be reallocated the next time they
are written. Any such sectors would cause an I/O error if the OS should
attempt to read them.
