Using Mini SAS Cable SFF-8087 to SFF8482 - https://www.amazon.ca/dp/B09F6BXLNQ?psc=1&ref=ppx_yo2ov_dt_b_product_details

 

Been using SATA drives with no problems and saw a deal on SAS drives, felt a little overconfident and here we are. I initially just added them to the array after creating a new config and they were working fine. I started a read-check over night and it gave 34 million read errors by the morning...

 

I cleared the drives and removed them from the array. Checked and reseated all power cables. One SAS drive seemed to be working fine so I swapped the power and data cables with the faulty drive and faulty drive still failed while 2nd SAS seems to be fine so far. At one point the faulty drive went missing and unraid couldn't find it, did a power cycle and it eventually came back online. I ran the extended S.M.A.R.T test on each drive and attatched it below, both showed no errors. At that point, i installed the pre-clear plugin and decided to run it overnight, it was working fine until the same faulty drive is throwing errors again.

 

I'm fairly certain I've tried everything and think its a faulty drive but I'm not 100% sure since this is my first time encountering this type of problem. The weird thing is the SMART test succeeded for the faulty drive but dissappears once the read failures start happening. I've attatched both versions and preclear logs as well. Good drive is still running the preclear.

Forgot to add some hardware

SMART looks looks fine, and the drive is dropping offline, suggesting more a power/connection issue, but if you already replaced cables could be the disk.

Is there no way to verify with 100% certainty that it’s the disk? It’ll cost me $100 to return it

 

also on the Amazon page, it seems one guy had to cover one of the power pins for the drive to spin up, would something like that be my problem?

Additional question

You can run a long SMART test, but it's only conclusive if it fails.

I’ve ran the long test and it checked out until the drive starts giving read errors and eventually drops out. If that’s my only option then I’ll just have to return it. Thanks for the help.
