All the dedicated server providers reuse components, it's normal practice. As long as the health of the HDD is 100% with no bad sectors there's no reason not to reuse it. When you get your new hetzner server check it with smartctl, hdsentinel etc, if any show bad sectors or health other than 100% I am sure they'll be happy to replace it for you.
