Bad block on brand new drive (alien.top)

Hello everybody!

I just received my new 20TB MG10 hard drives three days ago, and decided to run a badblocks test on them to check whether or not they were good. Well, here I am, with 2 disks (out of 6) currently reporting at least 1 bad block (I didn't let the test continue on the entire drive, but it's currently running a SMART extended test).

Considering I just purchased them, should I send them back? Or is it expected to see a few bad blocks on a 20TB drive? (Considering the capacity, it's not like I'm very surprised to see one bad block).

But at the same time, I'm well aware of the fact that it's not the number of bad blocks that's a bad sign, but just the presence of them, so I want to be cautious.

So because I've read a bunch of conflicting information (some people say 1 is okay, some others is any bad block is --> RMA), I'm not sure what to do here.

Thanks guys!

by "bad block" you mean a read error? what does smart say?

[–] MysteryDash@alien.top 1 points 11 months ago

Badblocks says 1 bad block found (0/0/1 errors), so it seems to be a corruption error.

I never had a bad block on a brand new drive. At least not a reported/ detectable one. So if it's truly a "bad block" (how exactly is it reported in your SMART data?) I would exchange the disks.
