Does anyone know how to do this??

I tested several things before I came to the above conclusions.  Simply copying the ZuneStore.sdf file did not suffice.  Some album art was missing.  Copying the entire Zune directory did the trick and was the only thing that worked.  Also, the file structure on my external drive is completely different than that of my main PC.  Despite the different file structure, everything worked fine.

Thanks to everyone for pointing me in the right direction!

Was album art the only issue?  It happenss because the software stores central copies of album art for the device (especially if you have embedded album art...)  But, this is not a big issue as album art is easily recoverable...  

Yes, the album art was really the only issue.  All tags were correct.   It's odd that happened too.  I have all my .mp3 files tagged correctly.  I use Mp3 tag, and I'm very particular as to how they are tagged.  When tagging, I ensure that each individual mp3 file has the album art embedded within the file.

There was only a small handful of songs that did not have the album art inside the Zune software.  However, when those same files were viewed via mp3tag you could clearly see the album art.

You're right: that is not a big issue.  But rather than re-apply the album art, I thought I'd try restoring the whole directory and it worked.

Again, I really appreciate your help as well as the others that have replied.
