Well, my wife has excellent vision and we were talking
about how pictures can be almost worthless after a certain point.
Several of those small connectors look similar. A Lightning
connector is about the same size as a microusb but the microusb
has 2 little key ways on one side that insure it can only be put
in facing one way.

There was nothing in the box except the drive which is
the reason for the confusion.
I thought the microusb with the 2 key ways was a type C
and that's when I learned it wasn't when one of those wouldn't
fit either way.

That's what I always thought. This makes all the sense
in the world.

I guess I was confused about the microusb versus the usb-C.
I am about to call Crucial Tech Support and get straight
on the end that goes in the drive.
Anyway, I appreciate the information. Thank you.
