My disk, which was previously ext4 has been formatted and Windows has been installed. I want to recover my previous files (family photos, ..) and I tried everything I could find on the internet.I first cloned an image of the disk to work on it, and I've tested Testdisk, but I couldn't do anything with it. In fact, when I analyze the disk I can find the partition (multiple instances, I don't know why) but when I list the files it doesn't find anything and give the message error: can't open filesystem. Filesystem seems damaged. I also tried to look for superblocks but still the same error. e2fsck tell's me : the superblock could not be read or does not describe a correct ext2 filesystem.
How can I recover damaged file from overwritten ext4 partition?
