I have triple boot System(Ubuntu,Kali,Win7) and I mostly use Kali linux(4.6.0-kali1-amd64). After each 3 or 4 successful boots i get this error ->
fsck.ext4: Superblock checksum does not match superblock while trying to access /dev/sda7 /dev/sda7: Superblock cannot be read may be an invalid ext2 filesystem. If yor device really formatted with ext fil system then
Superblock may have been currupted try running e2fsck
e2fsck -b 8193 <device> fsck exited with status code 8
And after this as root cannot be mounted due to this error & enters into (initramfs) Console where i have to run fsck command.
The Temporary Solution Worked for me is:
I simply ran
e2fsck -b "Magick Number" /dev/sda7 OR fsck /dev/sda7
and then rebooting kali worked perfectly but problem occurs again after some boots(as mentioned before). No such problem for Ubuntu. So how do I fix it? And Yes.. Does time affects on super block? Because there is incorrect time in my Kali but not in Ubuntu and Windows
NOTE: e2fsck & fsck didn,t worked for me
