Does ATIH 2011 prevent setting Windows7 on a drive

I'm running Windows7 Ultimate 64-bit. I went in to the control panel/System Protection to turn on Protection on the drive that contain my documents so I could use the "Restore Previous versions". When I attempted to do so I got an error stating "Could not apply settings for the following reason: THe Filename, directory name, or valume label syntax is incorrect"

If this error is correct and not caused by ATIH preventing the operation, how do I find the syntax problem?
