November 17, 20178 yr Hi guys, fairly new here, so I ask for your wisdom. I was running my unraid server without issues for about a month, then since I had some money lying around I decided to upgrade the PSU since the one I had earlier inside was a fairly old. So I powered down the system through the main screen and then swapped out the PSU and on boot it says that the array is stopped, looked around and saw this "Too many wrong and/or missing disks!" My cache drives are showing up seemingly without problems.. To fix the issue I tried: - changing the slots - changing the SATA cables - changing the power cable - putting in a fresh drive (which it detects, so its not a controller issue) Unfortunately still nothing. The drives in question are two 4tb HDDs, one Seagate and one WD red. Edited November 17, 20178 yr by Mr.Bobo
November 17, 20178 yr Are the missing drives detect on the controller/board bios? If yes post the diagnostics, if not unRAID won't detect them either.
November 17, 20178 yr Author no they are not visible either on the BIOS, also unplugged one drive and attached it to my PC and it wont show neither there.
November 17, 20178 yr Author Any idea what could have caused this? As to avoid future mishaps. I was wearing the bracelet while handling the components and as far as I know there was no damage done to them physically.
November 17, 20178 yr Not really, It's strange, I remember someone using the wrong modular cables assuming they were wired the same and damaging all disks.
November 17, 20178 yr It's hard to break one HDD from ESD. Even harder to break two. Even harder to break them at the same time unless you have a ESD gun or similar. What can break them is a bad PSU that emits out-of-limits voltages. But bad luck that this would happen just when you power off the system. Do you have any USB-cabinet or similar so you can test the disks individually while eliminating all other potential issues with your current machine? Another question. Can you hear them spin up when you power on the machine? Using a metal or plastic rod of some kind that you press against the case of a drive and your ear to the other end of the rod, it's easy to listen to the mechanical sound from individual drives without being fooled by the noise of the neighbour drives.

I have a USB adapter for SATA, but even using that it doen't detect anything. I can hear the drives spin but its very muffled and slow compared to a functioning drive of the same class, I think for some reason they are spinning much slower than they are supposed to. The odd thing is that the WD is fairly new (< 6 moths) so I can rule out the motor, the other one is the oldest drive in my array with 5 years. Thank the gods I have double parity, but shit I hope nothing happens while rebuilding... Ah other question, the WD is still in warranty you think I can RMA it?

Many drives uses dynamic rotation speed to reduce the power consumption. So not too much sound from them when they just spin in idle mode. But the test shows that it has power but that it without depending on cable or SATA port in the computer still fails to communicate. So now might be a good idea to contact the manufacturer.
