This is a collection of Macintosh software disk images ranging from the mid-80's to the late '90's. The formats include 400K MFS, 800 HFS, 1.44 HFS, original CD images & custom disk images that I have created. No guarantees that 20+ year-old software will actually work, although all the of the disk images except for the 400K MFS disks have been successfully mounted using Mac OSX 10.6 and Mac OS 9.2.2.

Summary : In this blog, we will share two methods to create a disk image-the first one using macOS Catalina’s Disk Utility and the second using a Mac data recovery application. 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.

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. 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.

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
The Disk Copy or Disk Utility feature for macOS can be used to create an encrypted disk image. Encryption means it requires a password to open or become available (to 'mount'). An encrypted disk image acts as secure storage space and can be used like any other disk image file. It may be copied to or created on network volumes or removable media, including Zip drives, USB flash media, or FireWire hard drives. Each encrypted disk image is protected by a password. The following document explains how to create, mount, and unmount an encrypted disk image. Important: If you forget the password to your encrypted disk image, the data on that disk image cannot be recovered.
Getting Started
Files can be moved to or from an encrypted disk image as easily as you can from a non-encrypted disk image. Please be aware of the following when using an encrypted disk image:
Backup programs will need to back up the entire image if any files within it have changed, since the image appears as a single file.
There is no way to change the password on an image file.
An encrypted disk image cannot be used as your home directory.
Complete the following steps to create an encrypted disk image for your version of macOS v. 10.4 or greater.
MacOS
Click Go, Applications, Utilities, and then click to open Disk Utility. Note: You can also click the New Image button and go to Creating a New Blank Image section.
Choose File, then New, then Blank Disk Image.
A New BlankImage window will display.
Enter a name in the Save As field. This name is used for the disk image (.dmg) file.
Enter a name in the Name field. This name displays when the disk image file is opened (mounted).
Select the Size of the image file from the drop-down menu.
Choose the Encryption option 128-bit AES to encrypt the image.
Select the volume Image Format from the drop-down menu. The default “read/write” option is recommended. Click the Create button.
Enter and verify a secure password when prompted and click OK. Note: Ensure the box next to Remember password (add to keychain) is unchecked. This ensures that no one will be able to determine the password for your encrypted drive by checking your keychain.
Mounting and Unmounting Encrypted Disk Images
After the encrypted disk image has been created, it will automatically mount for the first time and files can be copied to this location. The named volume disk image will display above the mounted source file.
When you are finished using the encrypted disk image, you must unmount the image. Drag its icon to the trash or select the eject button next to its icon in any finder window. In the example below, the encrypted disk image is named “personal.'
To mount the image again, simply double-click on the disk image you created. In the image below, the disk image is named personal.dmg. You will see it at the top of the list.
Enter your password when prompted. Click OK. Your disk image should be mounted. Note: Always remember to unmount your disk image when you are finished with it.
