Got disk error and ran smart self test and it came back with no errors?

In the show error log tab this is what it says.

Is it just warning that it is getting old?

In the full logs it also says passed.

Do i just acknowledge the error to get rid of it or is there anything i should do? Like is it not working right now?

I have a parity drive so if i understand it correctly even if it failed completely my data should still be available as usual.

Reallocated sectors are never a good stay, but if the number stays low and stable, it can be OK.

Here's a good video on HDDs with pending and reallocated sectors.
