I checked the cables just now, even moved it to a different SATA port on the motherboard but unraid still throws errors about this disk when I reboot.
I pulled the disk out of the array and put it on my external SATA dock on my Windows 7 machine and tried to check it using CrystalDiskInfo but it didn't even see the disk. The disk isn't showing up in the BIOS of my Windows PC at boot time either.
So all signs point to a bad disk. Time to start the RMA process with Newegg.
Thanks for your help!
