You can use Mac's Disk Utility to create a disk image for your USB, data traveler, SD card or other storage devices, which is a file that looks and functions like a disk: It contains other files and folders, and appears with a disk icon on your desktop when you open it.
Steps to Create a Disk Image (.dmg File)
- 1. In the Utilities folder in Launchpad, double click to open Disk Utility. (Sometimes, Disk Utility is saved in the Other folder in Launchpad.)
You can also just press Command+Space to open Spotlight search, type Disk Utility, and press Return to open it.
- 2. Then Mac will list all the disks and drives. Move your mouse to the disk you are about to recover data from. The disk named WININSTALL is what we need here.
- 3. Choose File > New > Disk Image from "WININSTALL".
- 4. Type a name for the disk image, and select where to save it.
Choose option from the Image Format pop-up menu as "read-only". By choosing "read-only", you can create disk image that's quicker to create and open.
Choose option from the Encrytion pop-up menu as "none".
Note: Make sure do not choose "compressed" but choose "read-only" for the disk image.
- 5. When all the above are done, click on "Save" to move on. At this point, you will get a poop-up window informing you to type your Mac's administrator name and password to allow this change.
When you launch UltData - Mac Data Recovery on OS X, you will see the next window. Click on "Load Image" and load the image file you just created. With this done, UltData - Mac Data Recovery will start to scan this image file for lost data.
