    My internal hard Drive 160GB running osx 10.4 is showing only 16GB available yet when I ad up all the main folders i.e. applications, users, system, past system etc. it comes to around 70GB.

    Seems like there's some kind of phantom files(75GB worth) that show up in "Get Info" but are nowhere to be found.

    Anyone had similar issue or can shed some light on this? Thanks

    Have you checked the Trash? It doesn't automatically get emptied.

    there is a large grey region called "space occupied by other files and folders" it's 92.5GB, this does not correspond to the color coded grey files on the left that total about 5GB. This space/files cannot be opened in finder and no information is available on it. Mmmm..

    I have just tried OmniDiskSweeper (very cool) and it tells me that there is on 41.3 GB on the disk, though my mac reads it as 132GB? I see that something is wrong but no idea how to fix it. Ideas welcome

    simple solution is to backup everything and erase your hd. Then re-sinstall from backup piece by piece. Of course if you want to view ghost files, this option will not work.

    Just for the heck of it, try Grand Perspective (another free disk usage mapper like DiskInventory X) and compare the results. Perhaps it will be more successful at identifying the mystery files/usage.
