Similar to this post, the file system on my home partition suddenly became read only. On reboot, my HHD containing this partition would not mount and I had to use
fsck to repair it. Now it works fine. I don't recall doing anything particular that day and I was wondering: what can cause this kind of unexpected corruption?
My computer is setup only with one OS: Xubuntu 16.04 and I have an SSD for the OS and an HHD for my home. Note that I am not trying to have an answer specific to my issue. I only want to understand better what are those types of corruption and where they usually come from.
