How to Recover Deleted DMG Files on Mac
'Hi, I have accidentally deleted a couple of DMGs that I would like to get them back. I have dragged them to Trash and emptied the Trash. It seems impossible to restore the DMG files. What can I do to retrieve the lost DMG files?'
Apple Disk Images are files (usually with the .DMG extension) which the Mac OS X operating system uses to store disk images, with optional data compression and encryption. Such images can be mounted as volumes to access stored data directly from the operating system. DMG files are mostly used for software distribution over the Internet, but Mac OS X users can create images of their own disks.
While data loss happens every, DMG files are no exception. And sometimes data recovery from such images is required. This brief article explains how to use Mac data recovery software for this task.

How to Fix the Corrupted DMG Files
What if the DMG files are corrupted? How to fix them? Unfortunately, when the corruption happens there may be little you can do to reverse it. However, there are a few things you can try.
Step One: Back up
Before trying to fix a corrupt disk image, make a copy of it. While you may be able to fix a damaged image, it is also possible that these suggestions may further corrupt it, so be sure to work from a copy.
Step Two: Use Disk Utility
Disk Utility has several routines you can use to try to clear the problem. Open the program and drag the disk image copy into the devices list. Then select it and in the 'First Aid' tab run a disk verification. If any problems are found, try repairing the image.
If the problem still exists, you can try resizing the image. For resizing, you might try the options for resizing just the partition, just the image, or both the image and partition since these will target different parts of the image structure.
Step Three: Mount the Images
Sometimes the problem is with the disk image mounter not being able to handle the image structure. You might try mounting the image when booted into Safe Mode (holding Shift at start-up). You can also try mounting the image in another operating system. Many times the utilities built to enable Mac compatibility in Linux and Windows use methods for mounting or converting a filesystem that may be more successful at getting a filesystem mounted than the ones Apple provides.
Conclusion
To avoid DMG or other Mac data loss, you should do the following things:
- Enable Time Machine Backup feature or data protection on Mac computer
- Never use RM Command or command terminal to delete a file
- Check selected files carefully before pressing Delete option

Disk Utility User Guide
You can use Disk Utility to create a disk image, which is a file that contains other files and folders.
Note: You can burn information to a CD or DVD using the Burn command in the Finder. See Burn CDs and DVDs.
Create a blank disk image for storage
You can create an empty disk image, add data to it, then use it to create disks, CDs, or DVDs.
- In the Disk Utility app on your Mac, choose File > New Image > Blank Image.
- Enter a filename for the disk image, add tags if necessary, then choose where to save it.This is the name that appears in the Finder, where you save the disk image file before opening it.
- In the Name field, enter the name for the disk image.This is the name that appears on your desktop and in the Finder sidebar, after you open the disk image.
- In the Size field, enter a size for the disk image.
- Click the Format pop-up menu, then choose the format for the disk:
- If the disk image will be used with a Mac that has a solid state drive (SSD) and uses macOS 10.13 or later, choose APFS or APFS (Case-sensitive).
- If the disk image will be used with a Mac with macOS 10.12 or earlier, choose Mac OS Extended (Journaled) or Mac OS Extended (Case-sensitive, Journaled).
- If the disk image will be used with a Mac or Windows computer and is 32 GB or less, choose MS-DOS (FAT); if it’s over 32 GB, choose ExFAT.
- To encrypt the disk image, click the Encryption pop-up menu, then choose an encryption option.
- Click the Partitions pop-up menu, then choose a partition layout.
- Click the Image Format pop-up menu, then choose an option:
- Sparse bundle disk image: Same as a sparse disk image (below), but the directory data for the image is stored differently. Uses the .sparsebundle file extension.
- Sparse disk image: Creates an expandable file that shrinks and grows as needed. No additional space is used. Uses the .sparseimage file extension.
- Read/write disk image: Allows you to add files to the disk image after it’s created. Uses the .dmg file extension.
- DVD/CD master: Changes the size of the image to 177 MB (CD 8 cm). Uses the .cdr file extension.
- Click Save, then click Done.Disk Utility creates the disk image file where you saved it in the Finder and mounts its disk icon on your desktop and in the Finder sidebar.
- In the Finder, copy your files to the mounted disk image, then eject it.
- Restore the disk image to a disk.For more information about disk image types, see the manual (man) page for hdiutil.
Create a disk image from a disk or connected device
You can create a disk image that includes the data and free space on a physical disk or connected device, such as a USB device. For example, if a USB device or volume is 80 GB with 10 GB of data, the disk image will be 80 GB in size and include data and free space. You can then restore that disk image to another volume.
- In the Disk Utility app on your Mac, select a disk, volume, or connected device in the sidebar.
- Choose File > New Image, then choose “Image from [device name].”
- Enter a filename for the disk image, add tags if necessary, then choose where to save it.This is the name that appears in the Finder, where you save the disk image file before opening it.
- Click the Format pop-up menu, then choose an option:
- Read-only: The disk image can’t be written to, and is quicker to create and open.
- Compressed: Compresses data, so the disk image is smaller than the original data. The disk image is read-only.
- Read/write: Allows you to add files to the disk image after it’s created.
- DVD/CD master: Can be used with third-party apps. It includes a copy of all sectors of the disk image, whether they’re used or not. When you use a master disk image to create other DVDs or CDs, all data is copied exactly.
- To encrypt the disk image, click the Encryption pop-up menu, then choose an encryption option.
- Click Save, then click Done.Disk Utility creates the disk image file where you saved it in the Finder and mounts its disk icon on your desktop and in the Finder sidebar.
Important: Don’t create a disk image of a disk that you believe to be failing or that contains corrupted information. The disk image may not serve as a reliable backup.

Create a disk image from a folder or connected device
You can create a disk image that contains the contents of a folder or connected device, such as a USB device. This method doesn’t copy a device’s free space to the disk image. For example, if a USB device or volume is 80 GB with 10 GB of data, the disk image will be 10 GB in size and include only data, not free space. You can then restore that disk image to another volume.
- In the Disk Utility app on your Mac, choose File > New Image, then choose Image from Folder.
- Select the folder or connected device in the dialog that appears, then click Open.
- Enter a filename for the disk image, add tags if necessary, then choose where to save it.This is the name that appears in the Finder, where you save the disk image file before opening it.

- Read/write: Allows you to add files to the disk image after it’s created.
- DVD/CD master: Can be used with third-party apps. It includes a copy of all sectors of the disk image, whether they’re used or not. When you use a master disk image to create other DVDs or CDs, all data is copied exactly.
- Hybrid image (HFS+/ISO/UDF): This disk image is a combination of disk image formats and can be used with different file system standards, such as HFS, ISO, and UDF.
- Click Save, then click Done.Disk Utility creates the disk image file where you saved it in the Finder and mounts its disk icon on your desktop and in the Finder sidebar.
