Hard Drive Troubles - Dynamic Disk

[rdmustang1]

Wondering if anyone can help me. I have an Areca 1880i with a 34TB RAID6 array on a Windows 2008 R2 system. A drive went bad today and the array immediately started rebuilding with a hot spare. The RAID array says everything is good. I noticed that certain directories on the server were inaccessible. I decided to reboot the system. Now Windows is labeling the array as an invalid dynamic drive (GPT).

Is there anything I can try in order to save the data?
