A couple of days ago I got the error:
UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY
when rebooting my 20.04 machine. The last thing I did before rebooting was running some game in Steam, the game tried to open a link in a web browser and that failed and I think the game crashed, iirc. After that, Steam just gave me a black screen, so I rebooted and got this error.
I am not asking how to reboot successfully, since I fscked manually, but what could be the cause? I am ruling out a hard drive error since the SSD is only a year old and SMART seems to be fine:
(By the way, I am not taking that 99C temp as accurate, it has always said that, must be a bug in reading the temp of the drive).
The partition that gave the error was /dev/sdc6, which is /home.
What could be the cause of the UNEXPECTED INCONSISTENCY error? I am guessing Steam did something, but is it possible that it would cause such an error?
