Since we're simply talking about being unpowered for a while, wouldn't a simple full format fix/reset all ECC errors? No need to scrap the drive.
Surely a cap/transistor temporarily losing charge shouldn't permanently destroy it!
Anyways, HDD for 6-24 months offline data storage, SSD for always-online data storage, and flash if you're a masochist like me.
I think tape storage has the best longevity in offline data storage, but it's been a while since I checked.
Tape presents its own share of problems. If not strored in some very particular conditions, like temp, humidity, and others that I can't recall, they can stick to tbe adjacent layers, become brittle, curved, etc...
