I was trying to copy my EXT4 partition as backup and I accidentally putted my NTFS partition containing my data on the dd command.
Now my data is lost :(
I've tried testdisk but it wasn't able to find partition. What should I do?
Update: This was the command I ran:
dd if=/dev/sda2 of=/dev/sda1 bs=64K conv=noerror,sync
