Vista default document directory problem

I mounted a new drive (3rd drive, which is going to be a backup drive
exclusively), copied files over because the existing drive was a dynamic
drive not ntsf, so needed to re format and copy files back (another storey
for another application). Anyway, once I formated the new drive, copied the
folders back and forth etc., I can't seem to re set the start menu to re
associate with the new/old directory locations on my secondary d: drive.
Tried the properties, user set up nothing seems to point to allowing me the
option of changing the option??? any suggestions would be helpful to change
the target location back.
