In other words, you're playing Russian roulette as you cannot know
how long the drive will continue to run even with a growing number of
reallocated sectors. If you decide to keep this drive running, watch
above value carefully, but even if it doesn't increase quickly, there
may be sudden death of this drive.

This is worse than above. It ought to be zero. The internal hard-disk
controller has not reallocated these two sectors yet.

Here, afaik, the drive has failed to reallocate bad sectors.
"smartctl -t offline /dev/sda" may help.
