i have an ultra 2 2 gig card.

i am usually have about 1 gig free for movies. last week, i was seeing less than half that.

no matter what i did i could not see the rest of the space. adding up the numbers from card info still didnt show where all the space went.

i moved all the data from the sd card to my desktop and then reformated the card. once i copied everything back over, i had the 1+ gig i was expecting.
