Last night my computer suddenly started to make these chirping noises. I'm afraid they are caused by a partially damaged hard drive and am wondering if anyone can confirm this? I have recorded a short video so you can hear the sound (https://youtu.be/5v6c0bbidr4). I have some experience with broken hard drives but I haven't experienced this specific sound, nor was I able to find a similar thing online.
I have backed up all the sensitive data, so not much can go wrong. I'm just curious if it is my harddrive and if so, is it just a specific sector that is damaged and can I keep using it or will it break down within a few hours/days?
EDIT To rule out a defect/damaged fan, I decided to open up the laptop. The video above does not contain the clicking noise that is also occurring every now and then (the same noise as when turning off a computer by long pressing the power button). However, the new video from within the laptop clearly does (https://youtu.be/NBctHjfMCnI). And it seems pretty bad, so I'm guessing software won't be able to fix this problem and a new harddrive is my best option.
