My mac is turning 5 years now, it runs already long on SDD and old HDD is in an optibay. But HDD is a stock one and is turning 5 years as well. It's working ok, but tests with Disk warrior, Tech Tool and DriveDx indicated 2 bad blocks, besides I had issues with a couple of big files. And as I assume there can appear more.
As far as I know, HDDs have a special reserved space, that gets used, when bad blocks are found. So the question is can this reserved space be extended? If yes, then what software would you recommend for that?

No, it cannot.
Hard disk failures tend to be catastrophic in nature -- if enough sectors have failed that you have exhausted the built-in reserve and you are seeing "issues with a couple of big files", your hard disk is likely in the process of failing, and no amount of additional spare space will save it.
You need to discontinue all use of this drive until you can back it up and replace it. Any further use is likely to result in data loss.
