I did it. I was in a hurry and accidentally formatted a 200Gb Micro SD card in my external slot of my Android phone. It had every type of file you can imagine on it. Videos, Pics, PDFs, Word Documents, Rar, Zip & 7z files... and more. About 110Gb of data.
There are so many reviews that are sponsored, it's hard to find consensus on what the best software options are whether free/open source (preferred), and paid.
The second I did it I I turned off the phone and removed the card to try to prevent data being written to the card. I now plan to use Windows 10 Pro as my work bench for trying to fix this.
Suggestions?
