What would cause Windows ten to remove drive letters from my WD Black, 1tb Drives? I can still go to my bias and boot from them, but Macrium Reflect will not clone to them. My C: drive is an SSD. I use the WDs as part of my backup system. Thank you, Angster

Thanks for responding rgd.
Yes, they show up as healthy drives, but without drive letters. One of them used to be my C:drive. I cloned back and forth between them and Had (and still have) daily backups to a usb external USB drive. I lost the drive letters when I added a Samsung SSD 850 EVO 500GB as my new C:drive.
