How Security Descriptors and Access Control Lists Work
Now i would say yes to that popup question. The worst thing that could happen is you would need to go in and change the access so that everyone could access the files. While that is a PITA to do it can be done. I do wonder if you had files on the larger drive that the program is talking about. Maybe it is talking about the files in the original XP install before you did the clone. This is uncharted territory for me now.
