Well, went back to 3.4 but still am required to delete all tracks on my HD-5, or reinitiallize. It is error code 000066a3. Thanks Sony! I'm glad, in some ways, I upgraded from my Archos Jukebox Recorder to the HD-5, since I got it for only $250, but to be quite honest, I wish I had one of the newer IPods instead for the navigation ease that is the clickwheel vs. scrolling through hundreds of artists/albums (why the jump-by-initial thing is only for songs, not artists, is beyond me) the lack of on-the-go playlisting. So, now with this need to redo everything from scratch, I'm not all that happy. Guess I might as well reinstall SonicCrap 4.0.... or maybe just go to GYM.
