I have some real bad spots on a card I am using and the last file opened is bad. This means that everytime I do a reset and restore defaults and try to move to another file or folder, I lock up again. I have done a chkdsk /r on the card and it just quits after 17%. Any ideas, and why would a card go bad like this; it's the same card I had problems with last week but thought reformatting it would fix it. Is it most likely the card??? Don
