For some reason, my N800 keeps setting (or just thinking that) my MMC1 card (removable SD) to read-only. But, when I Get Info on the card, the checkbox is not checked. (And, since it is read-only, I can't even check/uncheck the checkbox). This has happened on two cards so far with no action on my part -- it just turns out to be read-only at some point. Has anyone ever experienced this? Also, I have been given a few ways to try to change the card's filesystem back to read/write, but I was wondering if anyone here has the "right" way to do this. Thanks, Tim
