I'll try moving the Windows drive to the SSD's port. This computer pre-dates M.2 by quite a bit. SanDisk just approved the RMA, but it looks like they aren't shipping out a replacement until they receive the old drive: "• Our normal processing and shipping time is 7-10 business days AFTER receiving your package." -- Rich On Mon, Feb 10, 2020 at 4:13 PM John Stoffel <john@stoffel.org> wrote:

That does sound like it died too early... do you have one of those USB-to-SATA devices you could use to plug into another computer just to see if it's alive?
Another option is to install Knoppix or some other bootable distro on a thumb drive and boot there to see what you find.
As for the Windows and GRUB issue, I'm not expert enough to make it work without some more details from you. It might be enough to just move the Windows boot drive to the same port that the SSD used to be on. Assuming it's a SATA port and not an M.2 port (which can be SATA).
