Hi masterwks8184, sorry for the delay. One of the internal hard drive appears to be faulty, to be sure you can remove one of the internal hard drives and run a test with DLG, if the test completes successfully try testing the other one. Check the link below for the steps. As soon as you replace the faulty drive, the RAID will rebuilt.
How to test a drive for problems using Data Lifeguard Diagnostics for Windows
You need to get the smart status of that drive (get both) and then post here so we can advise, it might be a faulty drive or it might just be the result of using green drives in RAID. The thing with those greens is the URE rate is specified as 1 error in a little over 11TB read, in reality it seems better than that though. But basically if you read enough data from your array you are going to have a drive drop and if it’s because of an URE there is nothing at all wrong with the drive.
You can use smartmontools with HDD Guardian (you need both, and then load Guardian) to see through an Intel ICH RAID.
