It sheds some light, but since the last post was on 10/12, I'd think that most people aren't still having problems. My symptoms are a little different after the firmware upgrade - before, individual files and some dirs became corrupt after Canola rescanned my library, but this happened quietly, and I only noticed it as albums dropped out of the list. After the flash, (and with a new 8Gb Transcend card), Canola's scanning again causes corruption, but with more serious results - the N800 locks up on the NOKIA boot screen, and after a minute or so, powers down. I just reformatted and checked the card under OS X, and it seems fine, so I'm trying again, this time with the card's lock switch on (though I'm not sure that'll save me). -T.
