Those errors are more likely signs of failing drive.

You should use the smartmontools to do a status check on your drive.


Hard drives have had SMART technology for years and Linux has had these
tools for just about as long yet no distro (that I'm aware of) activates
smart monitoring by default. That is a real shame since they are so
