What to do? Added Mirror and received this message.  

Hi I just installed a new hard drive and added it as a mirror to the main drive.
This popup came. I have no idea what I'm supposed to do with this info.
Any help appreciated.
This is a fresh Win10 Pro install.

Thanks in advance

Welcome to the forum. How are you mirroring. The problem is windows edges a disk signature to each drive so it knows what it is. If it's mirroring it is confused which disk is which hence the problem. Doing a mirror is a bad idea if c gets infected so is the other disk any errors on disk one will corrupt the second disk with the new shake ransomware it would encrypt both drives. It's better to image c so you can keep several copies to restored

Right click C, select add mirror. This popup came then. It's finished with the mirroring, and it looks like its rebooting normally.

But it's going to be in a back room with SQL database going.
No actual use on the machine itself.
So what to do with the pop up request ?
