I think I'm losin a large amount of disk spc due to a thingy called allocation unit slack. I found it when I ran norton cleansweep. when i view the used spc on one of the drives it shows me 18GB but when I select all files and view the prpties it shows me only 12 GB. how to solve this

PS: there are no hidden files
