Fixing Corrupted FileSystem in Linux

Published: 2017-10-13, Updated: 2023-06-19

The problem

Can't load Ubuntu: Superblock checksum does not match superblock while trying to open /dev/sda7

Solution:

In that case it is alarming about /dev/sda7 so we need to fix it:

sudo e2fsck -f -b 32768 -y /dev/sda7

Replace /dev/sda7 wtih your partition, is totally normal get a bunch of numbers scrolling in your screen (something like matrix)

If you get a screen like that, saying Filesystem was modified, then your filesystem was with problems and it was probably fixed

That's all, if you get the same problem with others partitions then just repeat the process

If you get a message like Invalid argument it's because you need to change the magic blocker to the right number for example 8193 instead of 32768
