This computer was updated to Windows 7 from Windows XP. It is a laptop. It's been working fine, but now when it is booted up it says "replacing invalid security ID with default security ID.

Looking around I think this has something to do with check disk.

It does this for a long time and lists many files that it is replacing the default security ID. Why is this happening and what should be done?

As far as I know, this user has no good backup.
