Ultra backup seperate computers

I want to use the my passport ultra to backup 2 seperate windows laptops. (Vista and Windows 8.1) Please advise how to specify files on the passport drive so that the backup for each computer will be saved to the specified file. The software is already installed on the computers.
When I have run a backup until now, the program confirms that a backup has been made, but I cannot see into which file the backup has been saved on passport. I would expect to see the name of the computer with the date the last date backup has been made, but this does not appear.
Please help and give instructions, thanks in advance.


The SmartWare will create two different volumes and you should find them inside the WDSMARTWARE.SWSTOR
