    Hi there,

    I’m not sure if I’m getting something wrong but it seems there is 96.53 GBs missing from my Mac hard drive.

    I’ve searched on Google and I see that some people have had similar problems, but when doing a search with ‘Omni Disk Sweeper’ and ‘Disk Inventory X’ it usually shows that they had a bloated file or folder that was the problem. If you look at the photo of my HD and the disk scans below the space that is missing is not even registered on the disk searches.

    My hard drive capacity is 384 GB (that’s after 116 GB has been given up to run bootcamp).

    And Omni Sweeper is saying the used count is - 247.3 GB (Disk Inventory X says - 233.2 GB)

    384 – 247 = 137 GB free space not 40.17 GB as it says in the ‘About this Mac’ window.


    Am I missing something or am I missing some hard rive space that isn’t even registered on the search?

    I see that it shows my ‘Other’ files as 0 KB’s. Is that normal?

    I’ve tried:
    Verify / Repair disk.
    Deleting PRAMS.

    It's probably Time Machine local backups, sometimes OS X gets confused and misreports disk usage/category in relation to backups. The giveaway is that Other does say "Zero" but clearly there is a large yellow bar for "Other" indicating a rather large amount of space used.

    Time Machine should be clearing these out as space is needed, which is why Finder and "About this Mac" would report different disk usage amounts. You can try disabling local backups and seeing if that clears up your space.

    I remember reading somewhere that the About This Mac usage calculation is based on the index from Spotlight...

    From what I can remember, if it hasn't updated against the index, or the index hasn't been refreshed after a major change (like a new Bootcamp Partition), you can end up with it looking a bit off.

    Try making Spotlight do a re-index, I'd imagine that would fix the disagreement between the long Other bar, and its supposed Zero size. Who knows, might knock other things into shape.

    Apple's instructions on forcing a re-index:

    Hey thanks for reply.

    After posting the message and going to sleep for the night, when i woke up the space was back. Hopefully stays that way!

    Cheers though
