It is always recommended to back up the data of your device for safety purposes because redoing one that you have already worked hard on. So the day has come when I want to come back to working on the first project and I've been unable to write the saved DMG image to an SD card. I wiped the card to use it for another project with plans to eventually come back to the project saved on the image. This saved it as a DMG file that mounts nicely on the Mac when I double-click it. So your dog chewed up the SD card holding your favorite Raspberry Pi project? Fear not – being smart you made a backup (as described above) and I am here to help you restore it onto a SD card. Restore Raspberry Pi backup using Win32DiskImager. 19:02:27 -0500: Erase “APPLE SD Card Reader Media” and copy the contents of “Raspbian.dmg” to it.Read on to figure out how to restore a Raspberry Pi SD card image. 19:02:27 -0500: Destination: “APPLE SD Card Reader Media” Since disk-utility archived the full SD card with partitions, I would assume is has a way to recover it going the other way.įull logs from Disk Utility: 19:02:27 -0500: Restore Disk Since this card contains three partitions with one being a blessed bootable partition, I would like to see if there are any ways to get my Mac to generate these for me. I guessed that the source was incorrect, so I tried opening the DMG and providing the virtual drive as the source.
However, my victory was short lived as it promptly showed me this error: Recovery Error: Could not validate source - Invalid argument. All seemed to be working since disk manager prompted me if it was alright to fully erase the SD card as well as my root password for permissions.
I selected the DMG recovery file as source while selecting the SD card bay as the destination. To perform this action I went into disk utility under the restore tab and entering the appropriate fields. I am currently attempting to restore this image onto another SD card to ensure the recovery process will work appropriately. The recovery image is currently 865.5MB large and seems to contain the correct information. After the lengthy installation was finished I created a DMG backup of all the partitions using the Mac's built in disk utility. I have a linux distribution that I installed on an SD card.
