I recently purchased a Lenovo P71 Laptop With a 256tb SSD Primary Drive and a 1tb Secondary HDD.

I have installed the latest free version of Macrium Reflect.

I use it to create Backup Images of the Main C: Drive (256tb SSD) and save the images on the 1tb Secondary D: Drive.

I created a USB Bootable Rescue drive on a Thumb Drive.

When I boot from the Rescue Drive, It does boot into the Macrium Rescue Environment.

However, When in the Rescue Environment, the D: Drive is not recognized. Other Drives, C: and any USB Drives are listed, but no D: Drive.

Windows 10 version 1709

Any ideas on how to Fix would be appreciated.
