I am hex editing a hard disk and I would like to mark some hard drive sectors as reserved so that they are not overwritten by Windows (Vista or 7). I think this is possible, since during a defrag, the disk says that there are some sectors that aren't movable.

How can I do this?

  • Unmovable clusters is a different thing. They belong to files the system cannot move for various reasons (e.g. the pagefile). – atzz Jul 23 '10 at 14:50

Have you considered marking them as bad blocks within NTFS? This will make Windows bypass them completely.
