I connected my NC to my laptop several times in an attempt to copy some docs over to the NC. I have an SD card in the NC but is a real pain to pull out and put into my NC so sideloading is much more convenient. When I drag a file to the NC (either the NC or the SD card as they appear in "my computer" and the my documents folder in the NC/card) I get a message "this disk is write protected" referring to my NC/card. Is there a setting in the NC I need to change?
Jack, it's possible that the little slider on your SDcard got moved to the locked position. But I don't know of any way to Write Protect the internal flash on the NC. Sorry.
