If Omni Disksweeper is not telling you where the space has gone, then
it's not the program you should be using. A good disk surveyor program (
such as Disk Surveyor!) will show you everything, visible and invisible,
and show you just how much space every folder and file is taking up.
You might, for starters, try restarting. This deletes your swapfiles and
anything in your /tmp directory. Also, remember, the Finder doesn't
update information about how much space you have left until you make
some change, such as deleting a file. m.
