I would say no. In a non high fidelity scenario, stress testing a drive is unnecessary and is only lowering its lifespan. You could do a few sweep tests to assure its working correctly, but if you're really worried about possible data loss, that's what raid is for.
Thanks for the reply, I just went with SeaTools for now and it didn't find any errors in the long test, so I'm somewhat confident that the drive is fine :D
that's what raid is for
No. Raid is for uptime. Backups are for data loss prevention. They are not the same thing.
SeaTools doesnt stress test the drive. A good stress tester is the Phrononix Test Suite. They have Windows versions and they have a live ISO you boot from so you can test all your hard drives. The tests on my system took 1 day and 12 hours but were VERY comprehensive and thorough.
