Passport not available as disk

I just picked up a "My Passport 25E2.

It doesn’t show up accessible anywhere on my XP computer.
I ran DLG tools Quick Text and it worked fine.
It shows up in the installed hardware list. Status is “working properly”

But it does not show up as a disk drive anywhere. How do I get the drive to show up as an accessible disk?

Never mind. Replaced with a Samsung disk which works fine.
