SOLVED More Bad Seagate Drives?

[Redemption]

After my last issue with drives, I dismantled my Server and called it quits. However, that only lasted three weeks; I could not help myself and built another NAS. I purchased new drives, different models.

I was going to burn in the drives per the suggestions on the forum, and after assembling the system, I ran;

smartctl -t short /dev/sdg

To my surprise, all the drives appear to be dying. I bought them from NewEgg. Someone told me last time that the Raid controller could be an issue or the cables. After seeing the Error rate, I removed the LSI HBA controller and installed the drives straight on the motherboard with no controller. After the change, the Raw Read Error Rate continues to increase. All four new drives have the same behavior. Are they shot?

The easy thing to do is compare the total LBAs Read (#242) with the Read errors (#1) and if they match, you're fine.

Seagate puts the total read together with the errors in a way that if there are zero errors, the overall value is the same as total read.

You can also give yourself a better view of it by modifying the smartctl command to elaborate those values properly...

smartctl -a -v 1,raw48:54 /dev/daX

SMART Results help

replaced my old WD Red 4x3TB RaidZ2 array with Seagate Ironwold 4x6TB RaidZ2. Overall Ive been happy with the drives other than they run a little hotter. Can someone take a look at the SMART results? Im concerned about the seek error rate. Seems like all the drives have this high count. Im...

Stretalla, thanks for the information. I am currently running the script to burn in the drives. It should be done running by tomorrow.
