Sandisk SSD not showing through USB

Solution
What does your disk manager show, fully? All drives...

From that diskpart screenshot, you don't have a 750GB drive you could've cloned....

I didn't clone it through the computer. I cloned it through an EZ Dock 3 device. The only other drives that would show on that Disk Manager screenshot are hard drives physically in my computer that I didn't clone.
