sdchange.exe.mui File

Lately my system is requiring a disk check about twice a week or so. When
the check is run it finds errors. Namely the error I seem to see is that the
file sdchange.exe.mui is orphaned. It moves the file from the sector, it
fixes the entry then moves the file back to the sector 7237 of the disk. In
a few days this happens again in the exact same manner. This seemed to start
immediately after SP1 Install for Vista Ultimate.
