the phone will all the sudden say "sd card removed, insert a new one". but i havent touched the card or anything. i'll take it out & put it in, nada. i'll put a spare i have in, & wala, it'll read it.
then i put back in the other one, nada. so i take it back out & put it in another phone (BB) & it'll read it. then i put it back in the droid & it'll read it. this is the 2nd time ive had to do this.
