Cannot add parity drive(s)

Featured Replies

I discovered recently that my 16TB parity drive crapped out.  I purchased (2) 10TB SATA drives to that I can have some redundancy. My problem is when I add either drive, Unraid does not see them. I formatted one of them on my laptop just fine, but it is still not seen in Unraid. I must be doing something wrong? BTW, the drive controller does not reside on the motherboard, if that helps. Attached is diagnostics file.

Connect one of them to the onboard SATA and see if it's detected by the BIOS.

It's still not recognized using the onboard SATA controller. I'm going to put it into my USB drive enclosure to see what happens

Do you hear/feel the disk spinning up?

It's a helium filled drive do it's hard to detect if it's spinning up. It is currently being formatted in  USB box right now, so I know the drive works. When it finishes up. It try the SATA controller again.

 

The drive is only recognized by UnRaid  server when in my USB enclosure. No other configuration work.

 

I tried swapping data cables, tried onboard controller, tried formatting first. Tried tweaking my BIOS, It's not even recognized by BIOS.

 

These drives have a "power off feature". I wonder if that has anything to do with it.

The drive might be affected by the 3.3v power related issue

I think that is exactly what it is. I found this on the drive data sheet.

 

"Second, if you put a new SATA HDD with this feature into a legacy chassis or enclosure, the drive may not spin up! The HDD is not defective. Some legacy power supplies provide 3.3V power on P3 (Pin 3), and this forces the HDD to get stuck in a hard reset condition preventing the HDD from spinning up."

 

I'm going to try to sever pin 3 on a cable.

 

Update:

 

Found a couple SATA adapter cables which do not use pin 3, Parity drive now recognized!
