March 18, 201115 yr So today my Unraid server started a parity check and I was greeted with pages and pages of the following errors. Below is just a clip from the logs after I rebooted the last time. I have checked all the power and data cables, reseated the drives in the Supermicro drive cage. Swapped the power cables around to see if I could make the errors migrate to the second drive cage with no change in status. Drives 1 through 6 are on the onboard controller, 7 and 8 are on an add-on card, and 9 and 10 are on yet another add-on card. Drives 1 through 5 are in drive cage 1 and 6 through 10 are in drive cage 2. So when drives 6, 7, and 8 started throwing errors the only thing I can think is wrong is the drive cage, but who has ever heard of a cage just going bad? Ideas? Thanks in advance for any ideas and help. I am getting these errors on drives 6, 7, and 8.

March 18, 201115 yr I have seen instances of a backplane on a server going toast on more than one occasion. A test would be to pull the drives out of the cage and hook them up directly to power and sata cables. Bit of pain, but then you would know if the cage is involved at all or not. Shawn
March 18, 201115 yr Author The PSU is a Cooler Master 750W, motherboard is GA-EP43-UD3L with a Celeron Dual Core... 4GB of PC2-6400 RAM. After some more testing, I lost drive 6 completely and now the network is showing connected but I can't even ping the gateway. So as of now I am leaning towards a bad motherboard, but I guess a bad PSU could cause these issues as well. Anyway, if anyone has any ideas on what else to try before I buy a new motherboard and PSU, let me know. Thanks!
