Has anyone had a problem that they could access their SD card but couldn't write from the n800? I have a 1gb card that I can read/write from an external reader and from my computer via the usb cable to the n800, but when I try to save anything - it says "File is read only" - anyone have this frustrating issue?

I've tried changing switching the cards from the inside slot to the outside and vice versa with no luck - the card itself seems to be set at read only.

I've also tried chmod -R 777 /media/mmc1
but it comes back as "chmod: mmc1: Read-only file system".

Anyone have ideas on this? I don't know how or when exactly this happened.
