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.

Drive reports 6 bad sectors after moving from old NAS to new NAS. (alien.top)

Hello,

So I've had this janky QNAP NAS for years. It's janky because my apartment got hit by lightning a few years ago and fried one of the ethernet ports.

Ever since then, I had been using it (against my better judgment) because the other ethernet port still worked so I was able to keep using it.

I finally got a new NAS (Synology) and two new drives and migrated all my data over. Whew!

But now I've got two empty slots so I figured I would move over the newer of 2 of the 4 drives from my old QNAP NAS.

But the QNAP has a weird issue... it never shuts down properly, possibly related to the lightning. Any time you tell it to shut down, it just reboots. So I basically told it to shut down and once it seemed close to rebooting, I just pulled the power cord.

Then I moved those two newer drives over to the Synology NAS which is when it told me that one drive has six bad sectors. The drives are encrypted by QNAP's OS if that matters. So I was planning to wipe them anyway.

  1. Is it likely that the improper shutdowns contributed to the bad sectors?
  2. Is it likely that wiping the drives could solve this somehow?
  3. Should I not use that drive?

Thanks

1. It's possible. But also could be appearing naturally.

2. Probably not. You may need to show us the SMART report.

3. Isolated cases are fine. If numbers are still growing, that's a bad sign.

I'm confused by Synology's OS and how you actually view the SMART report but it just says "Healthy" and now it isn't even showing the bad sectors anymore...
