On one of my drives, scandisk and also Norton Scandisk report problems with the Security Descriptors. They can't fix the problem at all. Upon reboot they say problem still exists. Is this a serious issue, and should I re-format and re-install XP? On Norton's webpage, it says the MBR Master Boot Record may be corrupt beyond repair. How does this relate to Security Descriptors? What exactly are Security Descriptors? Otherwise my HD detects no other errors.
