Anyone that can help, would be appreciated.

I have a disk, which I want to reformat and use as a second parity disk.

However, any attempt to format through Unraid doesn't work.

I use the unassigned devices plugin and tried to mount the disk with the following log, just repeating indefinitely.

So maybe bad cable or not plugged in good enough.

But potentially issue with the controller port or with the disk itself.

But the machine obviously have big problems trying to communicate with the disk.

No need to reformat, parity has no format so all you need to do if the disk is working properly is to select it in the parity 2 slot while the array is stopped. Trying to use UD to work with it is counterproductive.

 

However, like @pwm said, the disk doesn't appear to be communicating properly.

 

Attach the complete diagnostics zip file.
