Thank you for your response. To be more clear I should maybe add, that I have not to do with drives beeing altered while the system is running. The drives content can be altered e.g. by the computer of a friend who I gave the drive out to. I tell it here, because it seems, that the answer is biased towards detecting changes done to files on a drive while running on a system able to monitor the drives activity.
