More than one WD Elements not recognized

When I connect more than one WD Elements 4TB to my computer, only one is recognized. I can connect each one independently and each is recognized, but each one gets assigned the sane drive letter.

Can you tell me how to get both recognized at the same time, with unique drive letters?

Welcome to the Community.

If you are using Microsoft Windows, then you are experiencing what is known as a signature collision. Please visit the following link for additional information:

That solved the problem. Thanks!

My pleasure.
