The drive has been only been powered on and used for read over the last 3+ years. CrystalDiskInfo reports it’s bad but CrystalDiskMark shows decent read/write speeds. Only wrote to it in the very beginning when I dumped a lot of archives into it. Otherwise, very few actual write cycles which is making me think it’s still ok to use. However, this isn’t a NAS drive and is consumer-grade bought many years ago.
Yes, it’s an external drive. Specifically WD MyBook
Commenter didn’t say it, but also the IO board may be bad too. Drive may be fine if you crack it open and treat it as an internal drove. (Note you may be forced to reformat it so the data would be lost, but functionally it might be fine)
