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.

Seagate SMART results raw values are very odd. (alien.top)

Hi folks, I've got 4 old 2TB Seagate enterprise drives used on my QNAP NAS. Even from new the QNAP NAS has never been able to read the SMART values right and I figured it was because the NAS is old and doesn't know how to read Seagate values. Additionally it was the same across all the drives.

I recently used Seatools to diagnose my drives and I can't figure out the 'Raw' values because they are astonishingly high. Basically across almost all rows, my normalised value is at the Worst value, but SeaTools reports OK. Raw values for example of Uncorrectable Sector Count is 72057594021216256. Which... is more than the number of sectors I have. How do I interpret these raw values?

Read Error Rate 9295715
Retired Sectors Count 6597069766656
Seek Error Rate 2859671186
Spin Retry Count 16492674416640
Airflow Temperature 521928735
Pending-Sparing Count 72057594021216256
Offline Uncorrectable Sector Count 72057594021216256

You could usually see weird values on Seagate drives on 3rd party software which gets the smart data, and usually everything was fine with the Seatools. I wouldn't be much concerned since Seatools showed that the drive is ok. Actually, if you have proper backups, I wouldn't really worry about it.
