I logged in to the system recently and found that my parity drive seems dead. I tried to unmount it and remount it, and now it does now show up in the system at all. Before I did anything, I downloaded the smart report and have attached it to this post. I don't know how to read this stuff as I'm not that savvy with this stuff and hope some of you guys might be able to help me.

That SMART report is empty, suggesting the drive was already offline. Does it show in the BIOS?

I have 2 identical drives and one of them seems to have issues. I cant find any of them in the bios, but the other one is working so i dont know.

Bios vendor: CWWK

Core version: 5.27

Compliancy: UEFI 2.8; PI 1.7

Project version: CWRKA03

Swap cables between those two and see where the issue follows.

I have a 6-bay NAS with hot-swap drive bays, but since I only had two drives at the time, I only connected those two to the motherboard. I got some extra cables and connected all the bays, then moved the bad drive to another bay. After doing that, I was able to find it again. I just ran a SMART short self test and will attach it to the post.

SMART looks fine.

How strange. The extended test just finished, and I'm attaching that one as well. Can there be a fault with one of the cables? Or maybe the hot swap rack in my Jonsbo N3 cabinet is broken.

There can, or with a slot.

Thank you for checking out the SMART reports, and for helping me.
