Fuze external memory cards indexing ONLY when somethings is changed inside

I am sure this is by design and not going to be changed. There are so many ways in this day and age to change anything on that card. Many people, myself included, have card readers, or external card readers… heck you could even put the card in your digi-cam and chage the files on it that way. If you take the card out and put it right back in there is no way the Fuze can possibly know that it is the same exact card and nothing was changed on it. The only way it can tell what was changed… is to scan and read the entire thing.
