OS windows 10 pro, trying to set up mirror drive, 1 TB drive with data on it, want to mirror to a brand new 2 TB drive, these are both HDD, my system recognizes the 2 TB drive and shows more than enough unallocated space, when I try to "add mirror" I just keep ending up at a dialogue box that says there is not enough space on disk to complete the task. I have downloaded EaseUS partition manager but don't see anyway for that to help. Both HDD are GPT.

Any help would be appreciated.
 
Solution
A "mirror" needs two drive of the same size.

Secondly, why a mirror? If for data protection, there are better ways to do that.
