When I plug my mobile broadband device and looked to my hd's info, the size of the used area constantly rises. There is only 45 gb left on a 250 gb hard drive while i only filled 95 gb. I checked /var/log and nothing unusual 25 mb size. I used whatsize app to find where all that invisible data is but couldn'T manage. Whatsize says there is 45 gb left in the hard drive but also shows the sum of used 95 gb.

any help please.

MacBook Pro, Mac OS X (10.7.4)

    Did you get WhatSize from the AppStore?  If so, it doesn't have the "As Admin" feature that lets you see everything. 


    If you got it directly from the maker, click the "As User" icon in the toolbar, enter your Admin password, and re-scan your drive.


    Also see Where did my Disk Space go?

    WhatSize should show it. Can you post a screenshot of the WhatSize window, like the sample in the green box of Where did my Disk Space go?

    Option 1:


    I was able to reclaim 20 gig of HD space. Do you have an iphone or ipad? If so, you when you sync those devices iTunes makes a backup. Over time and multiple devices I had amassed about 20 gig in backups. If this is the case. Open iTunes go to Devices in the preferences panel and delete older backups. Problem solved.


    Option 2:


    Do you have any software that uses a scratch disc or audio software that caches internet streams. These to can create huge file without your knowing. Search your drive for large files that have large Caches or files.


    Also if you run Paralells (PC emulator) its backup can get enormous. Check for that if you use.


    Hope this helps.

    That's pretty strange -- as you said, both the title line and sum of top-level folders is about 100 GB, but the sidebar selction says 200 GB. 


    Are you sure you ran Verify Disk on your internal HD, and Disk Utility said it "appears to be ok"?   Directory corruption is the only cause of such a discrepancy I've ever seen.




    It's clearly not any of the usual hidden places -- /Volumes, /private, Versions database, Mobile backups.
