The first step is to run Disk Utility. On a Mac running OS X 10.8 Mountain Lion or later, which will be the vast majority of Macs, you can run Disk Utility by booting into Recovery Mode.

  1. Make sure the Mac is turned off. If it's not responsive because it's stuck on a grey, blue or white screen, just hold down the Mac's power button for several seconds until it gives up and shuts off. (Here's what to do to fix a Blue Screen of Death on a Mac.)
  2. Hold down the Command and R keys, and power the Mac back up again. Keep pressing Cmd + R while your Mac is booting up until you see the Apple logo.
  3. Once your Mac starts in Recovery Mode you will gain access to Utilities. Click on Disk Utility.
