All the UNIX based operating systems, including Mac OS X, provide a DD command that you can use to make a disk image. This command is usable with command line interface. This command makes a bit by bit image of the hard drive.
Typically, for making a disk image, the disk you are copying from has to be capable of spinning. But what happens if your hard drive is becoming a doorstop? As long as it persists to spin, even with physical damage to the drive, DD command will get you out of the fire.

Once you have created a disk image of the affected hard drive, you can restore your data from it. It works as a backup copy of your hard drive. After reinstalling or repairing your corrupted operating system, you can use this copy to restore your data and can get your system in working situation.

It is a pretty cool data recovery utility that is very helpful in case if any disaster happens. But there are some unfortunate situations where the disk image created using DD command can’t be used. When you try to mount the disk image, you may receive an error message stating:

“No mountable file systems”
After this error message, you can’t restore or recover your data from the disk image and it could lead to the grave circumstances of data loss.
