Checksum Errors not going away

[Miniwehats]

So I have been getting a few checksum errors on a drive, about 4 - 20 that pop up every few days after clearing them and scrubbing. I decided to replace the drive with a new drive and that drive is also doing the same thing, I replaced the cable just the other night and still have the same checksum errors popping up. I ran a long SMART test on the drive and it passed....

I am not familiar with most of this data and cannot see anything really that stands out to me. I currently have 8 ports on my mobo filled so my only option is swapping around the ports and see if a different drive starts to do it on that port. Can you change drives around like that in a raid like this? Of course the NAS would be off...

Any help would be great! And I think I have a PCI sata controller somewhere around... its slower than my onboard but I think I could use it to test with.

 

[paleoN]

To recap, this is a new drive and a new SATA cable yet you are still seeing errors. The SATA port on the motherboard is the same and the PSU is the same.

I am not familiar with most of this data and cannot see anything really that stands out to me.

This should be zero, 188 Command_Timeout 0x0032 100 096 000 Old_age Always - 8. Though still fairly low, this is another sign there is a problem.

I currently have 8 ports on my mobo filled so my only option is swapping around the ports and see if a different drive starts to do it on that port. Can you change drives around like that in a raid like this? Of course the NAS would be off...

Yes, you can swap SATA ports around. Just make sure to keep straight which are which.

I would just swap the ports, but this is another option if the controller works.

To clarify yes, new drive. I believe it could be a refurb sent back to be though.... I tested in another port and the error follows the drive. My next option is to switch the sata power connection on the drive and see if it continues to follow the drive. If so then I guess I just happen to have bad luck and both drives doing chksum errors.

Didnt post my setup before... all about a year old now.
Corsiar 650TX PSU
ASRock A75 Extreme 6 Mobo
AMD A4 APU
16gig DDR3 2x 8GB Gskill 1600
8x 2tb/1.5tb Segate/Samsung drives. (yes I know im loosing space, slowly working on phasing out the 2x 1.5 TBs I have left in the aggr.)
Intel Gbic NIC

 

[Miniwehats]

I also grabbed the old drive that I replaced, I was about to RMA it but didnt send it because the replacement drive started giving errors to. Every test I throw at this drive passes just fine. So I am assuming its something with my setup :(

Also thoughts on torrenting to the NAS? I heard it was not recommended because massive reads and writes but its not like im running a seed box. Just torrent stuff every so often, TV shows and what not. I could torrent to a drive in my server pc and then move the stuff to the NAS its just annoying that way.
