What Is an OS X Recovery Disk? The OS X Recovery Disk is a native but hidden recovery volume on your Mac hard drive. This feature can be used to start up your machine and perform emergency maintenance services such as repairing a corrupted drive by running Disk Utility, surf the Internet to assess the problem you might be experiencing or download any necessary updates. Repair Disk Permissions is only available for volumes on which Mac OS X is installed. Verification compares the current permissions settings of an Apple-originated object against those specified for that object in its associated installation receipt.

While you can now try copying all files to another disk, this may result in lots of errors, and you may also not get all files that are still theoretically recoverable.
