2 identical 2 TB drives won't mount properly

[rgs42]

Hi 

I owned 1 x 2 TB my passport and thought it was so good I got a second drive.
The problem I ran into is the computer sees both drives as identical and won’t mount both drives at the same time.
I tried changing the drive letter for the new one though disk management and I also renamed the drive, but this just changed “both” to the new drive letter. How do I have one drive on say F and one on G at the same time?

The pc is the latest spec and runs w7.

Many Thanks

Thanks that seems to have done the trick. I havent rebooted yet to see if the effect is permanent or not. either way I can know copy straight from one drive to another! Cheeers
