Theres a VERY easy way of re-linking them Trevor.
So I can describe by example, what are the drive letters on your original and new (partition) drive?
First comment:
If you create the same folder structure on the partition as on the original location then the photos will be found automatically in most programs (e.g GA027, GA037, GA004 etc).
Its different in the photo linking programs e.g. GA030, but I'll describe that when you reply with drive letters.
