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 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.
