Question Can't mirror volume (Raid 1) in disk management


Active Member
Hi all,

I'm having trouble mirroring two identical HDDs in windows 10 disk management. I have one drive which has data on, and another empty identical drive. My method is right clicking on the drive with data on (disk 1), and selecting 'Add Mirror', it then let's me select the blank disk (disk 3), and gives a message about converting it from a basic to dynamic disk, I then click ok and I get a message saying there is not enough space to complete the operation.

You can see in the screenshot there is enough space on the blank disk, and I've even tried shrinking Disk 1 by 1024mb to see if that would help but i get the same issue. Any ideas how I can achieve raid 1 here? I've had it running before with these disks on a different windows install.

Thanks in advance!
