Well you probably don't have any smart monitoring tools installed.

67 sectors out of how many million?  Doesn't sound too bad.

Looking at my disks I find it ammusing that I can tell which order I
replaced the disks in my raid5 when I upgraded to larger disks:

# for i in a b c d; do smartctl -d ata --all /dev/sd$i|grep Power_On; done
  9 Power_On_Hours          0x0032   092   092   000    Old_age   Always       -       5888
  9 Power_On_Hours          0x0032   092   092   000    Old_age   Always       -       5885
  9 Power_On_Hours          0x0032   092   092   000    Old_age   Always       -       5877
  9 Power_On_Hours          0x0032   092   092   000    Old_age   Always       -       5882

0 reallocated on all the disks I have checked so far though.
