I had similar issue with album art. I did not move any music to the hard drive so not sure this will completely correct your issue...I downloaded AV Album Art Fixer and scanned all my USB music. The software was able to locate the correct album art for nearly every song (650+). The software then embeds the art into the mp3 file and allows it to be displayed properly. Album Art Fixer - Software Informer. It scans your albums of your windows media library for any errors in album art.. Again, not sure your issue is exactly the same, just trying to help.
