Hi guys,

Recently I got a Seagate 16tb IronWolf drive that just wouldn't recognize across a few different machines. It would spin up and then 'beep' nonstop as long as it had power. So I started the RMA process (which was entirely a hassle) and eventually got a new drive about a month later.

I plugged this new drive into an Unraid system that is separate from my 'main' server and began the preclear process, which finished yesterday night showing a bunch of S.M.A.R.T. errors specifically on the "Reported Uncorrect" attribute. I read some other threads about this, and the associated "backblaze" blog post about S.M.A.R.T. stats and basically it seems like this is the kind of stat that suggests a drive may not be very healthy or fall into the "early" age of the bathtub distribution of drive mortality.

 

Here's the report exactly: (serialnum scrubbed for paranoia)

Should I start the RMA process again based on this?

Should I run another SMART test?

 

TL;DR 228 Reported_Uncorrect on a replacement RMA drive, RMA again?

eventually got a new drive about a month later.

Probably not new, RMA replacements are typically inspected and reprogrammed returns, so you very well may have inherited someone else's issues.

 

I'd RMA again and see if you get a better result.

Yes.

 

What kind of a hassle have you experienced with the RMA process?
