So I use TestDisk to bring it back... The first time I did it it erase the whole hard drive... The second time it did restore the partition which is good. But now it is giving me a error massage when I try to open it in Files(Gnome).

You can attempt to fix it by executing this command in your Terminal: sudo fsck -y /dev/sda2 Replace /dev/sda2 with the appropriate partition you want to fix. share|improve this answer answered Jun 7 '14 at 16:41 Naveen 4,18642956 fsck from util-linux 2.20.1 e2fsck 1.42.9 (4-Feb-2014) ext2fs_open2: Bad magic number in super-block fsck.ext2: Superblock invalid, trying backup blocks... fsck.ext2: Bad magic number in super-block while trying to open /dev/sda2 The superblock could not be read or does not describe a valid ext2/ext3/ext4 filesystem.

ext3, ext4, etc.). Depending on when was the last time a file system was checked, the system runs the fsck during boot time to check whether the filesystem is in consistent state. System administrator could also run it manually when there is a problem with the filesystems. Make sure to execute the fsck on an unmounted file systems to avoid any data corruption issues. This article explains 10 practical examples on how to execute fsck command to troubleshoot and fix any filesystem errors. 1. Filesystem Check on a Disk Partition First, view all the available partitions on your system using parted command as shown below. # parted /dev/sda 'print' Number Start End Size Type File http://askubuntu.com/questions/478124/how-do-i-repair-a-fat-32-filesystem-partition-input-output-error system Flags 1 1049kB 106MB 105MB primary fat16 diag 2 106MB 15.8GB 15.7GB primary ntfs boot 3 15.8GB 266GB 251GB primary ntfs 4 266GB 500GB 234GB extended 5 266GB 466GB 200GB logical ext4 6 467GB 486GB 18.3GB logical ext2 7 487GB 499GB 12.0GB logical fat32 lba You can check a specific filesystem (for example: /dev/sda6) as shown below. # fsck /dev/sda6 fsck from util-linux 2.20.1 e2fsck 1.42 (29-Nov-2011) /dev/sda6: clean, 95/2240224 files, 3793506/4476416 blocks The following are http://www.thegeekstuff.com/2012/08/fsck-command-examples/ the possible exit codes for fsck command. 0 - No errors 1 - Filesystem errors corrected 2 - System should be rebooted 4 - Filesystem errors left uncorrected 8 - Operational error 16 - Usage or syntax error 32 - Fsck canceled by user request 128 - Shared-library error 2. Fsck Command Specific to a Filesystem Type fsck internally uses the respective filesystem checker command for a filesystem check operation. These fsck checker commands are typically located under /sbin. The following example show the various possible fsck checker commands (for example: fsck.ext2, fsck.ext3, fsck.ext4, etc.) # cd /sbin # ls fsck* fsck fsck.cramfs fsck.ext2 fsck.ext3 fsck.ext4 fsck.ext4dev fsck.minix fsck.msdos fsck.nfs fsck.vfat fsck command will give you an error when it doesn't find a filesystem checker for the filesystem that is being checked. For example, if you execute fsck over a ntfs partition, you'll get the following error message. There is no fsck.ntfs under /sbin. So, this gives the following error message. # fsck /dev/sda2 fsck from util-linux 2.20.1 fsck: fsck.ntfs: not found fsck: error 2 while executing fsck.ntfs for /dev/sda2 3. Check All Filesystems in One Run using Option -A You can check all the filesystems in a single run of fsck using this option. This checks the file system in the order given by the fs_passno mentioned for each filesystem in /etc/fstab. Please note that the filesystem with a f

I would copy/clone the the whole partition (using eg. dd) just to make data safe (don't forget to unmount the partition first). Then you can experiment with one of the copies to recover the files and fix filesystem; try to run fsck, or this might help as well: http://www.cgsecurity.org/ (photorec, testdisk) http://linux.derkeiler.com/Mailing-Lists/SuSE/2009-11/msg023
