I have tried all of the combinations of settings I can think of. Currently I have the size column allows show up as well as having "calculate all sizes" enabled. I can always find the value I want with get info, but some of my directories and files display the size while others don't. I can't figure out any real pattern, aside from the following: 1. my non-bootable secondary hard drive doesn't display any sizes in Finder 2. sometimes sizes will be displayed for a particular set of directories and files and sometimes they won't (this is not a case of not being patient enough for the values to be calculated). The only pattern here seems to be that all files in particular directory will show file size or none. 3. sizes can not work in finder, but will show up in path finder or vice-versa.
