Who are we?

We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.

We are one. We are legion. And we're trying really hard not to forget.

My old laptop died so I took the SSD from it in hope to use it as external drive. I wanted to just overwrite it with dd for security but I decided to go with f3 as that would also give me the opportunity to test the drive. Sadly, bad results came back

Yeah, barely used. Just the LBAs written/read doesn't seem to make sense.

Any better ideas than paperweight?
I have tested it when it was new, it had no errors.

I can’t see the SMART data. May be something in there that gives me more information. Seems odd to me that an SSD would just go bad out of the blue - but if you’ve not turned on the drive or laptop in a while, that could be why. But honestly, it may just be fine after a full drive write - couldn’t hurt to try zeroing it w/ dd.

SSDs don’t like being left unpowered for more than a few months. All flash storage, actually. If you take out an SSD and stick it on a shelf for a few years, it’s unlikely that it’ll lose data - but it’s absolutely technically possible, and many companies won’t cover such data losses by warranty after a specified period of time.
