Testversion X1 v8 capabilties

Hello,
Dearly hope someone can help me:
Just started to test X1 search v8 on my Win7 machine. It indexes nicely all Outlook folders and other datafolders from c:\my userfolder (i.e. C:\Users\MyUsername\Documents). So far so well.

I need to add a drive D: to the index-pane; how do I add a harddrive or USB-drive? (actually, I came to X1 only for the need of searching drives
other than C:)

Thanks in advance for any helpful reply!
HWK
