Windows 10: Can't create mirrored drives

I've been trying to create mirrored drives using two Seagate 5 TB drives Disks 4 & 5 that have the same available space. All goes well until I get to the very last step and I get the error message "The operation is not supported by the object." Is there something I'm doing wrong? I start with two drives whose space is unallocated and follow what the "wizard" tells me to do.

How to create mmirror drive in Windows 11?

I want to create a mirror drive on my Windows 11 PC using the internal 512GB SSD as main and internal WD 500 GB aux drive. I have attempted to follow online suggested steps to do so. However, I can not get beyond the "ADD Mirror Drive, etc.". All options are "grayed" out. Is there a trick to how to do this?

 

Mirrored Partition

Hi ABC. I'm Greg, 10 years awarded Windows MVP, here to help you.

How are you planning to mirror a partition? Normally mirroring is for an entire drive, like RAID1 mirrors. However I don't recommend it because I've seen too many lost files when one drive dies and the files are lost. You're better off with real time backup to the cloud along with periodic backup imaging using an app like free Macrium Reflect.

However if you still want to mirror a volume, I'd for sure have another backup method in case you lose both drives. Mirroring means exactly what it says, it exactly mirrors the changes you make on one drive to the other. Here is how to mirror a volume in Windows 10:
