Yes , I've been reattempting the test. Is there anything there that would indicate the problem is this drive? Just so I can use it when claiming warranty

The Failed collumn says Never

How can I find out if it's a read failure?

I've done several attempts and it doesn't complete it. How come it doesn't show the disk as unhealthy or damaged? Can I claim warranty on this?

I've checked the smart attributes. Also I've done both a SMART short self-test and SMART extended self-test. First one was ok, second one doesn't complete. It says: Interrupted (host reset)

It's these: https://www.amazon.es/gp/product/B08HMCBHG5/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 Molex to 2x SATA power.

I'm, quite honestly, a novice. How do I get to the bottom of this?

Yes I am using splitters. Is this bad? Shouldn't it have been a problem from the start?

Also, the check is VERY slow. It mayu take several days according to the estimate.

I shut down the server, checked the wiring and booted again. I've started a new check but the disk still looks more or less the same. The weird thing is that the disk status (disk 2) shows as healthy:

Thank you for the help and fast replies, I'll check the disk and report back.

I used the GUI, and followed the instructions in that thread. I'll have to check the cables. The disk icon opens this log:

Could overheating cause this?

That will take a couple of days, I'll do it ASAP. Is there anything else I should do beforehand/mean time?
