That wouldn't explain the SMART data reporting pending sectors.
According to spec, a drive may not reallocate sectors after a read error
if it's later able to read the sector successfully. That's probably
what happened here.
Drives are consumable items in computing. They have to be replaced
eventually. Read errors are often an early sign of failure. The drive
may continue to work for a while before it fails. The only question is:
is the value of whatever amount of time it has left greater than the
cost of replacing it?
