Create a Disk Image Using Disk Utility on macOS Mojave
macOS Mojave’s inbuilt Disk Utility provides an option to select a mounted storage drive be it internal or external SSD/HDD and create a disk image (.DMG) file to a location other than the source disk. The systematic steps to create a disk image of a drive using Disk Utility are as follows:
Open DiskUtility and select the storage drive from the sidebar
Go to File > New Image > Image from “DriveName”
Give a name to your disk image file and provide a destination to save the file
Click the Format popup menu, then choose your required option
If you want to limit the access of this disk image file, then click the Encryption popup menu to set a password for its access
Click Save to continue the imaging process
Click Done once the imaging process is over
Disk Utility mounts the image file’s disk icon on the desktop and sidebar of Finder. You can use the mounted image file to open its content.
Create a Disk Image Using a Mac Data Recovery Utility on macOS Mojave
The third-party data recovery utility, Stellar Data Recovery Professional for Mac also allows you to create a disk image (.DMG) file of the inbuilt Mac storage drive/volume or an external storage device. The logical steps to create a disk image of a drive using the utility are as follows:
Step 1)Download and install Stellar Data Recovery Professional on your Mac with installed macOS Mojave (or later macOS/OSX)
Step 2) Launch the software and select RecoverData from the main interface
Step 3) Click the ‘2nd‘ icon present at the top of the interface and select CreateImage
Step 4) From the “CreateImage” screen, select a drive or a volume to create an image file
Step 5) If you wish to create an image of the entire selected storage location, click Next
Step 6) If you wish to select the range to create an image, click the AdvancedSettings
From the “SelectRangetoCreateImage” screen, drag the sliders to define the starting and ending sectors of the image file
Click Close and then click Next
Step 7) In the “CreatingMediaImagetoSave” dialog box, locate the destination where you wish to save the image file
Step 8) In the “SaveAs” text box, type the disk image name and then click Save
This completes the disk imaging process using the software. Unlike Disk Utility, macOS Mojave does not mount this image file for you to access its data. Nevertheless, you can keep this newly created disk image as a backup and use it to recover data at the time of data loss.
