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.
there's pending and uncorrectable sectors, stop using it. is this an external drive? considering the read error rate it might be caused by a cable issue, or possibly even the power source.
back in the days when i had no drives i'd zerofill the whole drive and perform a bad sector check, then partition it so that the bad sectors are skipped then use the remaining parts. i don't recommend doing this if you can afford proper replacements though, and it's also very likely to get worse over time.
