I'm a little confused. I assumed that your project would check the pages of a
*shut-down* database or one in recovery (single-user) mode as part of
recovery after a crash or HW failure. We don't really want users running the
database in normal mode if there's any significant chance of data-page
corruption.
Can you back up and explain what you're trying to accomplish with this tool?
