Hello,

 

Just did a pre-clear on a new 12TB HDD and it failed during the Post-Read verification step. Not sure why. Attached is the pre-clear disk log.

 

It looks like everything in the clear worked fine, just reading failed. Is that something I can ignore? I'd hate to have to run all this again since it took 62 hours.

Have you done memtest?

Uhhhh I can't say that I have. I'm not 100% confident on what memtest is, but a quick search shows that it might be for RAM. Is that not right?

Bad RAM is a possible cause of post-read verification failure. And bad RAM is very serious. You shouldn't even attempt to run any computer unless memory is working perfectly.

 

Memtest is on the boot menu.

Oh interesting. I'll run it now. FWIW I've been using this setup for over a year and it's been working perfectly fine. Just an issue with this new drive's post-read.

Okay, memtest complete. It was a pass! That is good news.

 

What's next?

Preclear the disk again to see if you can get rid of that pending sector.
