Drive reports 6 bad sectors after moving from old NAS to new NAS.

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
