Yup you were right. After the repair disk 6 came back so 12 has to be the parity drive. I appreciate the help!

I was just doing that to be safe? Since the output of disk 6 says to run the command with -L its safe to attempt that?

Hello Friends, Forgive me for i have sinned. My USB drive died and I never set up back ups I have made a new USB drive and I was trying to mount my drives to see if maybe by chance I made a back up on my array. When i was tying to figure out what drive was my parity drive I noticed that I was seeing two drives that were unmountable when I only had one parity drive. Is there a way to tell which was my parity drive and which was my data drive? Disk 6 and Disk 12 are the ones that are unmountable, Diag attached. tower-diagnostics-20241003-2133.zip
