Since you just swapped out drives, it would be prudent to check the cabling (power and sata) to all the drives and the motherboard (unplug and replug in)  Right before unRaid tries to mount the drive, you've got a ton of errors:

which could be consistent with bad cabling.

Opened up the case and re-confirmed all of the cable connections.  When I power up the server and hover over the drive I see a message 'Device is disabled, contents emulated'.

So is this different than your OP? Is the array started? Post another screenshot.

Thanks for the reply.  I will upload a screen shot when I get to the machine later.  The drive that reported the issue has an X next to it and when i hover over it I see the message I mentioned in the previous message.  I did not want to start the array until I received confirmation that it was OK to do so.

According to the legend in Help, the parity drive is also emulated, which is nonsense.

 

Will it let you start the array? If so then the way forward would seem to be to rebuild the drive then try to recover the filesystem on it, but it's unclear what it thinks the state of parity is. Do you have another drive you could rebuild to?

This is the problem.  There is no parity drive to rebuild from.  The parity drive was just pre-cleared to add to the array.  It was after or during the preclear when the error started.  The drive is ready to run the parity sync, but now one of the data drives is showing errors.  The timing is horrible.
