A few weeks back, my 3500 didn't start-up as usual, it just "hang" there.

On the VAF-forum, there's a discussion going on regarding bad quality on differnet SD-cards:

For both the last updates for my 3500, I used Kingston SD-card.
Maybe the start-up problem was due to this card?

What are you guys at AFS use for card-brand? Sandisk maybe?
Maybe it's worthwhile to re-update the software in the 3500 using another brand of SD-card?

Thanks.
