> For the recycler, have you had any issues or concerns with reused hard drives?

Do you mean buying used ones? I've never had an issue with them at all, no.

I never donate my old hard drives. I keep them forever, as a kind of last-ditch backup. I have a collection of them that goes back to late '80s.

At this place, everything they sell is as clean as if it were new, inside and out.
