Mac Gems: Recovery Partition Creator adds OS X Recovery to any drive
One of the best features introduced in Lion (OS X 10.7), and available on every version of OS X since, is OS X Recovery. The OS X installer creates an invisible, bootable, 650MB partition—a portion of a drive that the operating system treats as a separate volume—on your startup drive called Recovery HD that includes a few essential utilities for fixing problems, restoring files, browsing the Web, and even reinstalling OS X.
The Lion, Mountain Lion, and Mavericks installers should automatically create the invisible Recovery HD partition the first time you install one of these operating systems. However, that doesn’t always happen. You can find out if your Mac has the Recovery HD partition—and, thus, OS X Recovery capabilities—by launching the Terminal app (in /Applications/Utilities), and then typing diskutil list
and pressing Return. Locate your Mac’s startup drive in the resulting list of volumes; if you have a Recovery HD partition, it will show up as “Recovery HD” (preceded by “Apple_Boot”) just below the name of the startup drive. If you don’t see a Recovery HD partition on your Mac’s startup drive, you can’t use OS X Recovery.
