Recover partition or repair broken superblocks on Ubuntu

Music used: Dance of the Pixies by Jens Kiilstofte https://machinimasound.com/music/dance-of-the-pixies/ Subtitle available. After moving the partition, the checkdisk reported error, and all my data was lost. The first thing you should do is to check, if the superblock if the problem: sudo fsck.ext4 -v /dev/sdx (x means your case, in my case the broken partition was sda4) If you get something like "the superblock could not be read", then list all your backup bloks: sudo mke2fs -n /dev/sdx To get access to your partition again, try all the backup blocks sudo e2fsck -b block_number /dev/sdx If it is not resolved, download TestDisk: http://www.cgsecurity.org/wiki/TestDisk Choose the corrupted partition Aanalyze it List the files Select the files you want to save (or select all) Choose destination and wait until it restores your stuff. I hope this could help.
