Yes. Be sure to mark the drive as bad so it does not get reused.
Data Hoarder
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 (tm) ). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.
Check for Uncorrectable sector count. As long as that is zero, your reallocated sectors were reallocated without any dataloss.
Modern hdds are designed to reallocate sectors in order to "self-heal" during the warranty period. So reallocated sectors may not spell immediate disaster. Just normal and expected behavior.
If you think the hdd is going bad, avoid writing to it. Only read and rescue your data ASAP.
Remember to make backups of the healthy drives as well.
