Been looking all over, and can't seem to find my specific issue. I've seen lots of threads where the Finder is showing more storage than is even available on the HD when empty. Mine seems to be the opposite. My MBA thinks there is 80GB+ on the disk, but when adding up the sub-folders it's nowhere near that. I've turned TM off and removed the snapshots, which seemed to solve a lot of other folks' problems, but not mine. Need some help here please.
