I often listen to audio or watch movies at night, and fall asleep with my N800 on. With the charger cable being an unsecured pole-style, the charger often doesn't stay plugged in, and the battery dies overnight.

I started using two 8g SDHC cards when support became official. Now whenever the battery is completely drained and the machine shuts down it's corrupting my SDHC cards to the point that, if they're in the N800, it will randomly reboot until I remove them both. I have to reformat the cards to use them in the N800 again.

I don't think anything is wrong with the cards, other than some sort of bad write or something that renders the O/S unstable. They reformat fine, and I never actually lose any of the data on them or anything. I'm not sure if the same thing happens with regular SD cards or just SDHC. I've got some SD cards that I should probably try with it. I did check to see if using the internal card as extended memory or not made a difference, and it doesn't.

Anyone have any idea what's going on? It's not a showstopper, but it is damn annoying having to reload everything back onto the cards.
