Mac OS X Snow Leopard offers a First Aid pane. This feature of Disk Utility lets you check almost any disk for errors, as well as repair any errors that it finds. Here are the two exceptions when the buttons are disabled:

• The start-up disk: Disk Utility can’t repair the start-up disk, which makes sense if you think about it, because that drive is currently being used.

  If you have multiple operating systems on multiple disks, you can boot from another Mac OS X installation on another drive to check your current start-up disk. Or you can boot your system from the original Mac OS X installation DVD and run Disk Utility from the Installation menu.

• Write-protected disks: Although you can use the Disk Utility to verify CDs and DVDs, Disk Utility can’t repair them.

  You usually can’t repair a disk that has openfiles that are currently being used. If you’re running an application from a drive or you’ve opened a document that’s stored on that drive, you probably can’t repair that drive.

To verify or repair a drive, follow these steps:

1. Access the Applications folder, and then open the Utilities folder.

2. Open the First Aid pane.

   The First Aid pane displays a list of volumes on your Mac.

3. Select the target volume/partition in the list at the left.
