My (super old) laptop's internal hard drive has a dark spot on it.
I removed my HDD for cleaning dust and noticed a dark spot on it.

It is a HGST 1 TB 5400 rpm HDD. Aged about 1.5 years.

I believe this was caused due to heat as I keep my laptop on 24x7.

Is it bad for my HDD? HD sentinel reports my HDD health is fine.

Should I be worried?

It looks just like some wear on the lable nothing much or it could be overheating and it may be slowly killing your hhd. Boot it up with the hhd and than shut it down after a while of the hhd moving and then take it out fast and see if it is warm.

Yes, that might be heat related.

But it may not have anything to do with the drive at all. It might just be residue from the part of the laptop case that was next to that spot on the drive.

If everything is working, don't worry about it.

Hey there, vijay_001.

Keeping the laptop cleaned is crucial for it's life. Depending on your environment and having in mind you keep it on 24/7 (like I do :) ), perhaps cleaning it twice a year is not a bad idea (as well as changing the CPU thermal paste every now and then). In my case I have a lot of issues with the hair that my Siberian husky sheds as well. Using a cooling pad is a really good way to reduce the generated heat by the laptop's components.
As for the HDD itself. Run some tests just to be on the safe side with the diagnostic tool (as it sounds like you've checked only its SMART data, but please correct me if I'm wrong). You could also monitor the drive's temperature (normally for most HDDs the max is 60C° while operating, but you better check that out for your drive model specifically).

Hope that helps.
