To start with, I know I can user ev3dev but as this is for my son, he want's to use code blocks and I'm struggling to get it all working as expected...
Initially there was an problem with ev3 not getting mounted at all, and I managed to get it solved by flashing newest firmware to the brick so it is now running on v1.10E
I've tried this on windows and works, device mounts and I'm able to upload file to it - it works... but my son do not have access to windows machine and I'm looking for a way to get it working on Linux...

When I run fsck.fat there is an error but I'm worried that is will brick the device when I allow this to do any changes... here is output of:
