N8 - some music is "unknown"

Question

Hi all,
Is there a way to "hard reset" the music library on the N8?  The reason I ask:
When I got the phone, I also got a 32GB microSD card and transferred my music to it (takes up ~96% of the card; it's around 4700 tracks).  No problem.  Then every once in a while, I get more music, and transfer the new tracks to the microSD card as well; also no problem.
Until the last couple of times, where the files transfer to the phone no problem, but they show up as "unknown artist" and "unknown album" on the phone, and the album art doesn't show up.  Instead of track names, the music application shows filenames.  The music does play though.
I tried "Refresh Library" a few times and each time it thinks for a while and then says "1 song added" but never adds any of them.
I don't normally use Ovi Suite to do anything with the music, but just for fun I fired that up and checked out the music library on the phone.  It shows the same thing that the phone does (which makes sense, I suppose): all of the tracks are there, but these new ones (and a few others) are "unknown."  Ovi Suite (3.0.0.282) doesn't give you the option to edit metadata, and neither does the N8.  For fun, I transferred the tracks from the phone to the computer using Ovi Suite, then opened them up in an MP3 player on the computer (MediaMonkey) and it showed all of the correct metadata.
Since almost all of the tracks show everything correctly, what I'd like to try to do is wipe out whatever internal list the phone has of the tracks so that I can do "Update Library" and see if the clean sweep picks it up.  Any hints on how to do that?  Or other ways around this?
Thanks!

Answer 1

Nobody responded to this but there have been other threads for other phones that seemed related.  For posterity: I resolved the problem thusly:
1) Connect phone to computer in USB Mass Storage mode (not OVI Suite).  This will make the phone do funny things, but (unlike previous models such as the N97) all of those things appear to reverse themselves.
2) Go to the G and H drives (Mass Memory and your micro SD card, if you have one) and in each go to the Private directory and delete the following three subfolders: 101ffca9, 10281e17, 10282bc4.
3) "safely eject" the phone from the computer.  For good measure, after the phone was done re-finding itself I rebooted it but that may not be necessary.  In either case, give it a minute or so to play with itself.
4) Go to your music library; it will be empty and the phone will re-scan and find the music.
That seems to have worked for me.  Hope this helps someone else ...
