EXT4-fs error (device sdb3) __ext4_find_entry:1530

[GarriHD]

Hey guys. I recently installed Pop-Os 19.10 and things went bad really quickly. I have an SSD on which Pop-Os is installed and a HDD on which I have Windows 10. The HDD is divided in two parts one I also use on Ubuntu the other one is only for Windows. So yesterday I wanted to play some games on Steam. My games are installed on my HDD since the SSD is small 120-ish gbs. Minutes after starting the game Dota in this case I got the following errors:EXT4-fs error (device sdb3) __ext4_find_entry:1530system-journald(546): Failed to write entry (9 items, 317bytes) ignoring Read-only filesystem.
