Hi Shmerl,
I don’t have much experience on the Debian, but for the drive bad blocks reporting, since you have a 480G drive, I wouldn’t be too worried unless we see a rapid increase in bad block counts, in another word, this is still within acceptable range.
For the temp of the drive, it is within spec and you should not worry about it, if you run a lot of write on the drive the temp will raise a little bit, but I don’t see any problem with it.
