I just had to build a new PC because the old one was dying. So I used the database recovery feature in Media Center, and it did restore my database, however, because I also had to move my music files to a different drive, once Media Center detected the files had been moved, it only kept the ratings I had for a portion of the songs, but not the rest, so now I have thousands of songs that no longer have ratings anymore.
I tried to redo the database recovery using the same database backup, and the same thing happened again. At first all the original ratings showed up, but as soon as Media Center detected the files had moved, and started relinking them to the new locations, a large portion of the relinked files in the new location would lose their previous ratings.
Why did this happen? How can I get those ratings back?
