Unfortunately, the code above will only work on Windoze. On *nix systems you have to deal with local/non-local drives, mount points etc. Can get pretty complicated, but not impossible.

Algorithm is:
Read appropriate 'fstab' file to find volumes and mount points
Execute the 'df' command ('massaged' for each *nix flavor) for each mount point
Parse the output of the 'df' command

Much work, unless you only need to support Windoze, or very few flavors of *nix.
