The reason for not going the "install it in the machine and see" route is this is one of those miserable laptops that I need to tear down in order to get the thing in and then I have to put it back together, at least most of the way, to test it. I prefer to know that I've got a functioning device before doing that.
John, the result of diskpart is that the disk is listed, showing 931GB (which is less than I would have expected, but I know that's got to be it). I had a brain fart and had entirely forgotten that when I have a brand spanking new clean drive that I needed to initialize it and create a simple volume. It's now initialiized GPT with a quick format to an NTFS volume with the drive letter G:
Now I guess it's time to clone my existing C: drive to G: and do the drive transplant tomorrow.
