I bought two Passport essential SE.

Unlike first  one, I have a trouble with installation with second one. When I connected new one,

automatic installation guide did not come up and could not find  WD smartware.exe file.

Instead, I found and executed WD SES Driver setup file and WD Smartware setup(x86)file.

But it did not work. Moreover, it made the first one I bought unworkable.

I must have done something wrong. I might have toi try uninstall and reinstall.  Any ideas?

Quick question: Are you using both drives in the same computer?
