I have even reinstalled windows thinking that this error was a corrupt file that I couldn’t get to.
When I reinstalled, I went the slow way and formatted the disk completely before install, and have diskscanned a number of times.
But it still says some file can’t be defragged, and when I look at the report it shows no files in the list. If I do analyze, it shows only one file being fragmented, and that’s the ntuser.dat file.
What I need to know, is if this is anything I even have to worry about? I found out about pagedefrag, from www.sysinternals.com, and have set that to make sure things like my pagefile are defragged as necessary when I reboot.
