Hi everyone,

 

When pre-clearing two new 12tb drives, one drive generated 1024 errors and cannot be mounted - see attached images and diagnostics. Could this be a cable issue or is it likely to just be a straightforward faulty disk that needs RMA'ing?

 

Many thanks for your advice.

When pre-clearing

FYI that was clearing, pre-clearing means clearing outside the array.

 

Disk dropped offline, most likely a connection issue, but since there's no SMART more difficult to say, check connections and post new diags.

Thanks for the response and advice.

 

I checked the connections and plugged the sata from the drive above into a different socket on the SATA card. Started the array again and ran clear on the disc - no errors this time, but 2 CRC errors. Formatted the disc and thought I was fine.

 

I started moving files onto the array, and everything seemed fine, so left it for a couple of hours. When I came back, both this drive, and the other 12tb drive I added recently, are displaying errors - see image attached.

 

I am assuming now that this is the SATA card i'm using (Ziyituod (https://www.amazon.co.uk/gp/product/B07T8XNQT6/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1)) or I need new sata cables, but I would have assumed if the cables were faulty it would be a binary issue.

 

Grateful for any further advice you may have.

That controller uses a SATA port multiplier and is not recommended.

Given the errors I have described above, it that a likely source of the problems?

It's possible, even likely:

 

Nov  9 05:07:22 Teletran kernel: ata7.15: limiting SATA link speed to 3.0 Gbps
Nov  9 05:07:27 Teletran kernel: ata7.15: softreset failed (1st FIS failed)
Nov  9 05:07:27 Teletran kernel: ata7.15: failed to reset PMP, giving up
Nov  9 05:07:27 Teletran kernel: ata7.15: Port Multiplier detaching
Nov  9 05:07:27 Teletran kernel: ata7.00: disabled
Nov  9 05:07:27 Teletran kernel: ata7.02: disabled
Nov  9 05:07:27 Teletran kernel: ata7.00: disabled

But can also be a cable issue.

Many thanks for your continued patience and advice. My main concern was that it would be a disk issue, but that does not appear to be the case. Going to order some new sata cables and see if they do the trick. If not, I will look to get a better SATA card!
