Hi, I’m trying to back up my raspberry pi sd card by using the most widely recommended backup tool: Win32 disc imager.
A few weeks ago I gave it a go and despite it saying ‘write successful’ - the output file was invalid. There was no file extension - I tried to add the file extensions .img, .rar, .zip .IMG but no joy with any.
Last night I gave it another go, noting my every action in case I did anything wrong! The only thing I can think of is to type the file extension in the output name before the write, but I don’t see how this should make the image valid.
I’ve looked into this as deep as I can, including using a linux explorer along with adding/removing file extensions but nothing seems to work… Hoping this is something silly as I can’t find this issue anywhere on Google!
