4.1. Create Image using Disk Utility

Disk Image is a mirror image of any storage device from which you wish to recover data, such as ”Internal or External Hard Disks”, ”Pen Drives”, ”Volumes”, ”Storage Cards” etc. When you create an image, scanning process is not performed, instead a copy of the selected source is saved as DMG file. You can start the recovery after completion of drive imaging.

Create Image option is not available within the Stellar External Media Recovery software. You can create an image of different storage devices and save them as DMG file by using the Disk Utility option of MacOS. You can create an image of all types of storage devices such as Internal or External Hard Disks, Pen Drives, Volumes and Storage Cards using Disk Utility.

The image you create by using Disk Utility will be of same size as the selected hard disk, pen drive, or volume. Ensure that the location where image file needs to be saved has sufficient space to store the image file.
