My main HDD is about 2.5/3 years old. All that time, it has been running with about 40-45 (temperature).
I have had a HDD failure before and it was really frustrating, I don't want that to happen again.
I was working on a project then suddenly the computer started to slow down (I had many applications running), so I closed some of them and just for precaution, I ran HDTune to read SMART.
To my surprise, It had
raw read error rate:6, then after 1-2 minutes, it increased to
9. I've checked SMART data like 1 week before, and it was
raw read error rate:0.
Is it possible that some files have been corrupted?
How critical is raw read error rate? I assume I have to start making backups? or start making backups ASAP?
It's a western digital HDD.
