Nonsense. He has a disk with 2 million sectors, and 4 sectors have
been remapped. Such a number is common. Only if the number increases
at an increasing rate is the disk failing. That's why SMART has a
threshold (10 here); note that the current value is 100.

He has an unrecoverable sector. If that sector was in use, it's data
was lost. If that sector was not in use, no data was lost. If the
number of uncorrectable sectors rises, that is a problem.
The OP should enable Automatic Offline Data Collection, which will scan
the entire disk for bad sectors "every 4 hours", and remap them if they
are still readable. If sectors are unreadable when that is being done,
then/ the disk needs replacement as data will surely be lost (sooner or
later).
$ sudo smartctl -o on /dev/sda
