WD RED and GREEN together - is it possible?

Hello!

I have My book live duo 4,0Tb which is working in Raid 1.

One hdd has bad status. I’m going to replace it on WD RED.

Mirroring/recovering procedure will be O.K. ???

I’m afraid to lost data… What do you think?

Why not replace it with the correct drive?   I assume it’s still under warranty, but you’d have to buy the RED drive…

I know. It contents important data, I cannot give it to someone.
