I use DaisyDisk and found out that I've lost 142.5GB out of 256GB SSD space being hidden as displayed in the attach captured image.

Can someone tell me how you resolve this issue and retrieve back the hidden disc space? Why are they hidden and used up so much of space? I do Time Machine backup every night I get back home. It never happen to my MacBook Pro... Pls help!... Screen Shot 2012-04-24 at 2.21.31 AM.png

    Maybe:

     

    OS X Lion- About Time Machine's "local snapshots" on portable Macs

     

    Open the Terminal in the Utilities folder and enter or paste the appropriate command line. Press RETURN and enter your admin password when prompted. It will not be echoed.

     

    To turn them ON: sudo tmutil enablelocal

     

    To turn them OFF: sudo tmutil disablelocal

     

     

    Note that turning them OFF will also delete all existing snapshots.

    Well, I went into the Disk Utility and veryfy the drive and the error messages appeared as per the attach captured image below:

    I then restart the computer and hold down "Command+R" till the "Apple Logo" appears and releases the keys.

    I selected the bottom most option (Disk Repair) and selected the volume and clicked "Repair Disk". Within 5 mins, the (green color) message reads "Your disk repaired successfully" and I gain back all my lost/hidden spaces to what I should be getting...
