My girlfriend is listening to some YouTube sleep music in the next room. The music is almost quiet enough for me to not notice it, but the one sound that does travel apparently is a percussive clicking noise.
Which sounds EXACTLY like the intermittent repetitive clicking sound of a dying spinning hard drive. Coming from the exact same direction as my two external hard drives.
I think I need to go to sleep. Being in front of my computer and hearing that noise is…unsettling.
