MiniSD actually. I had the miniSD card that game with the n800 in the Internal bay (with full sized SD adapter). Just right now i tried rebooting it and the miniSD didn't show up in the file manager. I tried other cards in that bay and it works fine. The card still works on my computer so I tried taking the miniSD card and formatting it with my computer but that still didn't work. I've read a few posts about people having problems with SD cards and the n800, but i can't figure out what's wrong. Anyone have any ideas as to what might have happened?
