I have a 2.0GB sandisk jump drive and when I delete items from it, I do not see any space free up on the drive. I cannot see the item on the drive anymore but Finder still shows the same amount of free space on the drive. Why is this? Is there anything I can do to get it to show up correctly? BTW, I can add some small items in the little free space it has and they show up and the amount of free space gets smaller when I put them on there but when I delete the same item, it vanishes but the free space does not come back.
