This is my first time using unraid for a server setup. I wanted to build a new server for plex and managing my media. Originally my server just had the drives thrown inside and left it but decided to setup unraid seeing alot of people like its ease of use. I currently have 1 500gb NVME drive for cache, 2 18TBs, 2 4TBs, and 1 1TB drive installed. I didnt know i had to format all the drives before adding them to the array so my plan currently is to move all the data to 1 18tb drive and add the drive to the arrary then work my way down from there. But adding one of the 18tb drives to the array gave me an error saying "Unmountable disk present:" and not sure how to fix it. The NVME was added just fine. I attached the logs below.
