Read on to know the steps and benefits of these methods. Also, make sure you avail the free trial version of Stellar Data Recovery application.

Disk image of an external or an inbuilt Mac storage drive is immensely helpful in recovering files in case the source drive fails or dies. You can create a disk image of your APFS or HFS drive on a larger storage medium and access it at a later point of time.

Create a Disk Image Using Disk Utility on macOS Catalina

macOS Catalina'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.

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 Catalina

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 Catalina (or later macOS/OSX)

Step 2) Launch the software and select RecoverData from the main interface https://rev-software.mystrikingly.com/blog/slot-city-download.

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 Catalina 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.

Recover Data from a Disk Image Using the Software

The methodical steps to use the .DMG file for data recovery are as follows:

Step 1) Launch the software and select Recover Data from the main interface

Step 2) Click the ‘2nd' icon present at the top of the interface and select Load Image

Step 3) From the 'Load Image' screen, select the .DMG file or else click Add to add the image file

Step 4) Click Scan to start the recovery process

Conclusion

We hope the blog helped you in understanding the practical details of how you can create a disk image file of a storage drive on macOS Catalina. By implementing Disk Utility, you can generate a disk image file and can open the automatically mounted image file from the saved location. On the contrary, by using Stellar Data Recovery Professional for Mac, you create a disk image file and use it to scan and recover lost, deleted, or inaccessible files.

Unlike Disk Utility, the software allows you to select the specific region of the drive for image creation. We recommend this method to recover files from a storage drive that is too big in size. For instance, if your storage drive has the data storage capacity of say 8 TB, then you need to recover data in portions. Free download the software to create an image, scan, and preview files. Register the software to save the recoverable files.

Overview

This gist details how to create or restore a disk image in Mac OSX. There are three methods that are described: Carbon Copy Cloner, Disk Utility, and CommandLine.

Disclaimer:
- I have no financial incentives to https://bombich.com or Apple.
- Always make a backup of your data, and make 2 separate backups before trying something new.
- The following steps have been tested and are a summary of my personal recommendations, but should be used at your own risk.
- If there is a chance of imminent data loss, contact a professional for assistance, and do not rely on a random person from the Internet for help.

Method 1: Carbon Copy Cloner (CCC)

This is by far the recommended method. CCC has been around awhile, and has a simple yet powerful interface that can serve multiple functions, including creating a bootable backup from a disk (like your internal hard disk).

To create a disk image, select the source volume and the destination volume. If you want to create a cloned copy of the source volume, then select a destination disk, but be advised that existing files may be overwritten.If you want to create a disk image on an existing disk, then select a folder instead.

To restore a disk image, follow the above steps in reverse.

Method 2: Use Disk Utility

Creating a Disk Image

This method is fairly straightforward, and Apple has a surprisingly helpful knowledgebase article that provides information as well.

The steps assume you are using Mac OSX High Sierra or later. The above link has information for previous OSX versions.

Step 1:

Open Disk Utility, then click on the external hard disk that you wish to clone (for example, 'ExternalHD')

Step 2:

Then select select File -> New Image -> Image from 'ExternalHD'
- Note: If you do not see your disk listed, that means you did not click on it beforehand.
- The options for disk image are:
  - read-only: this image will not be modifiable
  - compressed: this image will be a compressed version of a read-only image
  - read/write: this image will be modifiable, and will have the extension '.dmg'
  - DVD/CD Master: this image is compatible with 3rd party apps, and will have the extension '.cdr'
- Unless you have a compelling reason otherwise, select the option 'read/write'

Step 3:

This process will take awhile. You can also create a checksum of the image by clicking on the image, then selecting Images -> Add Checksum

Restoring a Disk Image

Apple has another surprisingly helpful knowledgebase article that provides information as well on these steps.

There really is only one tricky step.

Step 1:

Connect the external drive that will be erased.
Then open Disk Utility

Step 2:

Select the empty drive from Step 1 that will be deleted, then click the restore button.
This is the tricky step. All data will be (irreversibly) deleted from the drive that you select.

Step 3:

In the window that opens, select the disk image (it must end in '.dmg') that you will use to restore onto the drive that you just selected to be deleted, then click 'Restore'. This process will take awhile.

Method 3: Use CommandLine

This method should only be attempted if you are feeling adventurous, and if Method 1 and Method 2 are unavailable.

to erase a disk, use the syntax:

Create disk image

Use either the hdiutil or dd commands

Restore Disk Image

There are two main methods to restore a disk image: asr (Apple Software Restore) and dd. The dd command can be used as described above, but in the reverse order.
