This is probably something simple, but I've never seen it before...

I have a 4TB Seagate ST4000DM005 SATA hard drive. When I connect it to my Windows 10 PC (20H2) I end up seeing three new drives in my Device Manager:

- ST4000DM005
- Microsoft Storage Space Device
- Microsoft Storage Space Device

...and I actually get two drive letters appearing on my computer with about 7TB of space total.

I *think* that this is a compressed drive. I would like to wipe this drive and get back to a single 4TB device.

What do I need to do?

OK... I think I've found out what this is.

This looks like some kind of "drive combining" that pools disks together. It doesn't really make sense why someone would take a single 4TB disk and two pools of 4TB and 3TB on it. You still wouldn't have more that 4TB of storage on it.

I don't see the same issue with 2 x 4TB USB drives but I don't have Storage Spaces running which may be what you are seeing and as I understand Storage Spaces is exactly what it does [but I've been know to be wrong every now and then].
