Yesterday I've had the bad idea to try to follow this tutorial :
these are the commands that I have issued :
dd if=/dev/zero of=boot.mbr count=0 seek=2048 sudo apt-get install mdadm sudo modprobe linear sudo losetup /dev/loop0 boot.mbr sudo mdadm --build /dev/md0 --level=linear --raid-devices=2 /dev/loop0 /dev/sdc1 gparted /dev/md0
with gparted I have created a new partition table and I have formatted it with the ntfs file system,thinking that I was doing it for /dev/md0 and not for /dev/sdc1. sdc1 is the main partition table where were saved all the most important informations of my life. I don't know where I've wrong but now the partition is empty. What can I do for recover all the informations that there were before ?
