    Repair Boot Disk in Mac OS X Lion with Disk Utility & Recovery HD




    If you have tried to repair the boot volume before in Mac OS X before, you’ll undoubtedly have found the “Repair Disk” option is grey and unavailable within the Disk Utility tool. While this is still the case while booted in OS X Lion, you can repair the Mac OS X boot disk thanks to Lion’s Recovery Partition, preventing the need from using an external boot drive to repair the disk.






    Once booted into Recovery mode you’ll find the limitations on Disk Utility’s repair function has been removed, here’s how to do that.

    Repairing a Mac Boot Disk with Disk Utility & OS X Lion

    Reboot the Mac and hold down Command+R to boot into Recovery

    Select “Recovery HD” at the boot menu

    At the Mac OS X Utilities screen, select “Disk Utility”

    Select the boot volume or partition from the left menu and click on the “Repair” tab

    Repair Disk is now possible, click on “Repair Disk” to repair the boot volume





    While you’re in Recovery mode, you may also want to verify disk permissions and repair them, repair user permissions, and verify and repair other disks as well

    Organize, Tile, & Resize Windows Without a Mouse Using Spectacle for Mac OS X



    Spectacle is a free utility for Mac OS X that helps you quickly and easily organize and resize windows, without using the mouse. Apps like this make it much easier to view multiple documents alongside one another and can help to boost productivity, particularly after you remember the keystrokes to throw windows around the screen.

    Want a browser window to align to the left while a text editor is aligned on the right? Want to tile four windows into each corner of the screen? Easy. If you use multiple monitors, Spectacle will also let you push windows to the the other displays too.

    Download Spectacle free from the Mac App Store

    Spectacle is open source and works with Mac OS X 10.6 and 10.7. Here’s the full list of keyboard shortcuts you can use:

    Spectacle Keyboard Shortcuts:

    Center / Cmd + Alt + C

    Fullscreen / Cmd + Alt + F

    Left Half / Cmd + Alt + ←

    Right Half / Cmd + Alt + →

    Top Half / Cmd + Alt + ↑

    Bottom Half / Cmd + Alt + ↓

    Upper Left Corner / Cmd + Ctrl + ←

    Lower Left Corner / Cmd + Shift + Ctrl + ←

    Upper Right Corner / Cmd + Ctrl + →

    Lower Right Corner / Cmd + Shift + Ctrl + →

    Left Display / Cmd + Alt + Ctrl + ←

    Right Display / Cmd + Alt + Ctrl + →

    Top Display / Cmd + Alt + Ctrl + ↑

    Bottom Display / Cmd + Alt + Ctrl + ↓

    The keystrokes are fully customizable, and the only other preference options are to show the Spectacle menu bar item and launch at login or not.





    Even with OS X Lion’s new ways to resize windows, I find apps like Spectacle to be extremely useful, and once you get the hang of using them it’s hard to go back.

    Great Show of useful knowledge.

    I would like to add some more technical aspect of repairing a Mac disk. If your disk shows signs of more gruesome failure like Invalid Node Errors, Tree-Map corruption or directory structure failure then Disk Utility or Recovery HD wouldn't be of much help. The disk in question has to be treated with something more advance. These advance algorithms are offered by couple of software such as Disk Warrior and Stellar Volume Repair, both of them which are capable of replacing, rebuilding a new directory structure.

    Do try these options anytime you receive much bigger threat on your Mac disk.
