Setores externos do HDD externos pela primeira vez, algum motivo para se preocupar?

Question

Recentemente, o Windows me disse que pode haver um problema com alguns setores da minha unidade. Eu escolhi reparar, e gostaria de saber se há algum motivo para preocupação. É a primeira vez em dois anos que isso aconteceu, e alguns dias antes de acontecer eu acidentalmente ejetei outro drive e retirei este sem ejetá-lo com segurança. Eu também gostaria de saber se há algum programa que possa me dizer quais arquivos foram excluídos, para que eu possa colocá-los de volta no lugar deles.

O status CrystalDiskInfo mostra que está em uma condição "boa", embora não%.

Além disso, se eu mover o conteúdo desta unidade para uma nova, ela passará os arquivos corrompidos? Este é o resultado da verificação do sistema de arquivos do checkdisk:
