I have a WD Scorpio Black 320G running in a Toshiba laptop on Vista
(drive is six months old).No problems with the drive, but even after I
defgragment I can never get less than 38% drive fragmentation. Drive
health is “good”, and says “no need to defragment now”, whether I try
to defrag using Windows or Piriform Defraggler. Is there a reason why
it won’t defrag more than I can get it? 38% sure seems high to me.
