Certainly. but a minor error like this is not a serious flaw since the 
sector has already been remapped. This is a case where it is reporting 
that 1 sector is bad. If this were an increasing number I would 
certainly replace the drive. So, if my backup drive failed, I would 
certainly replace it, but not immediately. If one of my primary drives 
in my RAID reported errors, I would replace it ASAP.
