Windows 10: Storage Spaces and mirroring

If I have a drive that already has data on it, is it possible to setup a new Storage space and mirror that drive to it?For example; I have drive D:\ which has data on it. I want to add another drive for D to mirror to. Both drives are the same size, is this possible or will setting up the Storage Space erase the data on the primary drive?

Win10 Storage Spaces - Mirrored Pool Doesn't Release Space

Using Storage Spaces for a simple Mirrored Pool with (2) 4TB HDD's for a backup drive.

Setup was simple and easy with Storage Spaces reporting a formatted 3.75TB Mirrored Volume.

After test writing some system images and doing some disk speeds tests, Storage Spaces says drives are over 80% full with a warning, but there isn't any kept data on there.

Under Computer Management, the Volume says only 15% used.

So it's like deleted files (also deleted from recycle bin) don't get reported as free space back to the Storage Space Console.

I have also created a SIMPLE storage space with (2) SSD's, but deleted files and space seems to be reclaimed there.

I have enabled Disk Optimizer to run once a week but it doesn't help to reclaim the space on the MIRRORED volume of HDD's.

 

Storage Spaces Mirror 2 Drives?

Actually... no. If you plug out a mirror from a Storage Spaces mirror and plug into another Windows 10 machine, it will first warn you that a Storage Space is in trouble, but seconds later your plugged mirror is fully available. I just tried.
Interesting enough, you can keep working and modifying your now "reduced resiliency" space. When you plug the missing drive back to your real Storage Spaces machine it gets in sync and back to normal.

I came here looking for some more experienced users having tried this before, but I see that it's a bit crazy and no one has tried it. So far, I'm starting to believe this is a great way to have an always updated roaming media storage.
I wonder what would happen if the roaming media gets modified, it would be overwritten once back in the mirror?

Hi,

The idea is to mirror storage space, not the OS.
