Hi.  I suffered 2 drive failures.  1 of them is the parity, and another 1 is data drive.  Since I will have to rebuild parity, I will take this opportunity to assign drives to the array.  I've taken the data drive that failed, and copied the contents to a new drive (Drive X).  I want to add Drive X to the array, before it starts rebuilding parity.  I want to keep all data in all other drives, and Drive X.  Do I just assign Drive X to a new slot, assign a drive to parity, do a new config, and start?

You can do that as long as drive X was formatted by Unraid or the UD plugin
