All that the drive utilities are telling you is that there are currently no bad sectors, except for those already blocked out, and response time, etc. are within tolerance. Typically it's deterioration of the disk surface that causes drives to fail, and that process accelerates as more and more as the surface starts shedding. Yes, there are a certain number of bad segments on a new drive, but the initial check at time of manufacturing should mark and hide all of those. If the problems you found were on the first chkdsk ever run on the drive soon after purchase, I guess it's possible they were just missed in the q.a. process and damage may not go any further.
Good luck, and watch that warrantee period -- they are shorter than they used to be.
