If you can still see this after 7 months, can you please explain what you mean by “swapping the drives around” ?
I connected the new Ultra II to the power plug right next to the existing bootable SSD, connected a SATA cable from the new drive to one of the available SATA ports on the motherboard and have the same problem – the BIOS can see the disk, the brand and the capacity, but Windows Disk Management doesn’t.
The system originally came with Windows 7 or 8, not sure which (2014) and was updated to Windows 10 online when it became available.
Thank you.
