Anyone have any idea what's going on here? SSD is 120Gb so 111Gb sounds about right for formatted volume, the drive the unallocated space is on has the same hardware id as the SSD, needless to say I'm stumped. I've put this out to some fellow builders but they've only seen it during OS installations but do have the facility to amend it, I can't here. Diskpart and Comp Management don't allow to change anything about it...
Thanks in advance peeps...

that 8GB is some totally other drive. You don't have any USb drives or anything like that plugged in?

Open up device manager and go under Disk Drive and see what is all listed there.
