Greetings!

It is mostly fixed. Most human sized syncs will go without any trouble at all. When I was rebuilding my player after cleaning all my mp3 files (VBR header trouble), I attempted a 100GB sync, just to try and break it. It did. I broke the sync into two or three smaller syncs, all worked perfectly. This was over USB.

So, as long as you are not doing anything really out there, you should be fine.

Note: I didn't even bother to report or post those massive sync attempts. That kind of event is so rare, that I didn't think it too interesting. If there is any desire to try and replicate that error for troubleshooting purposes, let me know.
