I'm in the process of burn-in testing a new server and there's 1 SAS HDD (out of 10) that's reporting quite a high number of "Errors Corrected by ECC" compared to the others.

The system:

Chassis: Supermicro CSE-826BE26-R920LPB (Dual Expanders Backplane)
Motherboard: Supermicro X1oDRi-T
HBA: 2x LSI 9207-8i (only 1 is currently connected)
HDDs: 10x HGST 2TB 7K400 SAS2

The procedure:

After running memtest86 and memtest86+ on the server, I followed the [How To] Hard Drive Burn-In Testing (thanks @qwertymodo). You'll notice the ~8TB of data processed which is the result of badblocks default 4 passes.

The suspicious HDD:

Code:
root@sysresccd /root % smartctl -q noserial -a /dev/sdh
smartctl 6.4 2015-06-04 r4109 [x86_64-linux-3.14.50-std460-amd64] (local build)

Out of the other 9 HDDs, 2 had 0 errors, 2 had 1 error, 3 had less than 10 errors, 2 had less than 30 errors and then this one shows over 5000. Seems extremely high compared to the others.

This is definitely something I should be worried about, right?

Any suggestions on how to more thoroughly test this drive?

I'm thinking I should RMA the drive.

Thanks in advance!
