I have used Etcher to write the Raspbian image from a file to an SD card. Now I want to duplicate the SD card by reading from the card into a file on my Windows PC, then using Etcher to copy the image to other cards. What is the best way to copy the card image to a file?
Thanks for using balenaEtcher! It sounds like you’re looking to duplicate your Raspbian SD card after you’ve logged in and made some changes to the system. Is that the case? If so, you’ll need to turn the modified contents of the SD card into an image (a sort of reverse-Etcher). Unfortunately, Etcher doesn’t do that step. On Linux, you’d use the “dd” command. On Windows, you can run Linux natively with WSL (the Windows Subsystem for Linux https://docs.microsoft.com/en-us/windows/wsl/install-win10). With dd, you can create a new image of your modified Raspbian SD card with “dd if=/dev/sdX of=/home/yourusername/my-updated-raspbian.img” where “sdX” is the the SD card device name, not a partition. Without using dd, you may find some Windows tools out there (https://www.itechtics.com/convert-files-folders-iso-windows-10/). Once the image is created from the modified SD card (my-updated-raspbian.img), you can then use balenaEtcher to repeatedly burn it to fresh SD cards.
Did you have any success?
Thanks for checking. This looks like it will work, but I have not had a chance to try it.
