I have mechanical disk which runs 24/7. This night something happend in electricity grid after that my pc wont boot. Boot disk which is ssd and storage disk both where somehow damaged.
I tried to mount hdd and got error: mount /dev/sda1 can’t read superblock
Its scary because I dont know if it can be fixed or is it toast
Found one way to try and fix it
Solution was found here http://erikimh.com/linux-recover-corrupted-partition-from-a-bad-superblock/
Output would be something like this
Now you can try to fix it with this command
It took a while and I was lucky and disk was repared and I was able to mount disk
