nothing wrong with Norton, I really wish people would stop calling Norton products evil and comparing them to virii. I have been using these products for years on my own machines as well as many clients, without any of the gloom and doom that some of you spout.
Norton however, won't fix those errors, neither will chkdsk(it will simply write out bad sectors so they aren't used) If you want to fix this, get HDD Regenerator, it will scan the entire disk and actually repair any bad sectors it finds without affecting any files or partitions.
