drive reported as unassigned after repair

[Kelaifu]

recently had a power spike which took out 3 of my 4 WD reds, repair needed an IC switching from the burnt out controller PCB to a replacement pcb etc, which worked fine for 2 of the 3, popped em back in and they were fine. However one of the drives is now showing as unassigned. The serial number reported in unraid is the same as the one on the case of the HDD, so I don't think that's the problem.

 

I have a parity drive (the one which survived) so I would assume I can repair the array regardless, but I'd rather try fix this drives issue before doing that and in all honesty, I am clueless, this being my first issue with unraid since I set it up 4 years ago.

 

So, any advice on what steps I should take here to get my array back to its former glory would be greatly appreciated.

I added the zip, hope that's correct.

 

Thanks!

You started the array without disk1 so it's disable, you can justs rebuild on top.

You should also update to latest Unraid, since that release is very old.

isnt it possible to restart it without rebuilding it? The drive should already have all the data on it that would be rebuilt.

It is, but you'll need to run a parity check which will take the same time, just mounting/unmounting the disks will generate a few sync errors.
