I have done dmg resize to my .dmg file since my image is bigger than my dvd in which I want to burn it. However, some errors occur and my .dmg file is now corrupted. Can anyone explain to me why something like that happens and how can I retrieve my files?
Hi Kathy,
There could be several reasons why .dmg file was corrupted. Once file is corrupted, there can be a little chance to reverse it. Before you attempt to fix the corrupt file, make sure to save a copy of it and try the workaround on the copy of the file. Open Disk Utility and drag the copy of the devices list. Select the file you copied and run disk verification from the first aid tab. You may try to convert or re-size the file. When re-sizing, just re-size the partition, the image or both. There are 3rd party data recovery software that you can opt to use. You can also try to mount the file in another Mac or OS.
