Forum Question: HD Space fiasco and how to find missing space

I have a MbP that is giving me fits. It says I have only 80 Gb of space left on a 250 HD but when I run Disk Inventory X it shows only 46 used.
Any idea on how to find the missing space?

    What does it say when you use the system tools to check your hard drive (in Lion: Apple Menu, About this Mac, More Info, Storage). Perhaps that app you are using isn’t reporting things right?

    I am running Snow Leopard right now. I have used that app on my personal MB (the MBP is my school machine) with high levels of success. I am wondering where else things might be stored (such as within my library) that may have been duplicated or something of that nature.

    Is there another method for checking available space and what is using the already occupied space?

      On Snow Leopard is it Apple Menu, About This Mac, More Info (button). Then select your drive bus (Serial-ATA, perhaps?) and then look for your hard drive name. You should see “capacity” and “available.”
      Or, you can use the finder and select your hard drive. Then Get Info (Command I) and you will see Capacity, Available and User here too.

    I used command I and
    That is where I see only 46 GB available

      OK, so I’m confused now. OS X is reporting that you have 46GB left. And this program “Disk Inventory X” is reporting that you have 46GB left. So what is reporting that you have 80GB left?

    Sorry… OS X is reporting I have only 46 GB available. Yet the Disk Inventory X programs stated there is only 80 GB used on my 250 GB HD. So, I seem to be “missing” around 150-170 GB of space that doesnt seem to be used by anything.

    Clear as mud? :)

      Sounds like that “Disk Inventory X” program might be wrong. Or, you could be interpreting what it says wrong. Maybe you as a user are only using 80GB? So the rest is being used by the System and Library folders, and/or other user accounts?
      Go to your top level and select the System Folder. “Get Info” on it. See how much it uses. Do the same for Library and Users. Dig down deeper if you want. Be a detective.
