These days, hard drives probably scrub themselves periodically, looking for and rewriting sectors with high error correction error rates.
SSD’s definitely do this.
Even if hard disks don’t do this, mean time to repair is a crucial parameter in raid durability calculations. If you spin the drives up once a year, the mean time to repair is 6 months. Most raid systems are likely to lose data if it takes more than a few days to repair.
