Thank you for the clarification. This rec was very helpful. I was able to resolve the issues.

Definitely was cheap; came as part of a barebones/combo kit and was 6+ years old. Purchased and installed a new PSU. Attached are the diagnostics with the new power supply. Disk 5 is still disabled and unmountable. The SMART report shows no errors. Not getting any other errors. I think I can focus on repairing Disk 5. Can I repair and re-enable it?

I am not sure what's wrong; I've attached diagnostics. I changed to a new case and am now having issues with my disks. I have reboot several times (using GUI). So far I've had at least one of these issues: Disk 5 is always disabled. Disks are missing Disks are unmountable Disks are read-only Disks have read errors Current setup: Case: SilverStone CS380 [disks are now connected to a SATA backplane] Motherboard: Gigabyte GA-Z97-HD3 CPU: Intel Core i5-4690K RAM: 32GB DDR3-1866 CL10 (Kingston HyperX Fury 4x8gb) [changed from 2x8gb Corsair Vengeance LPX] PSU: Solid Gear 650W GPU: EVGA GeForce GTX 660 2 GB [added; there was no GPU in the system before] Disks: 1x 8TB WD White Label (EMAZ), 4x 4TB WD Red, 1x 4TB WD Blue [this is the always-disabled disk] When I changed the case, I also changed the RAM and added a GPU. I confirmed that the drives are fully seated in the bays. Changed to new SATA cables. The parity check said it would take 11 days. I'd appreciate any help troubleshooting. The system is currently shutdown. EDIT: Solved. Steps taken: Replaced power supply. Fixed Disk 5 unmountable state Rebuilt Disk 5
