WD Lifeguard Software

I have a my book 3.0 1 TB and want to put it through its paces before putting my data on it.  How can I run a WD lifeguard type software to check the drive.  My main concern is that the software I see is a boot type software and the my book is an external drive with no operating system??

thanks for the help…

It does not matter if the drive has not OS installed. The WD Diagnostic for Windows will find the drive as a USB unit and test all the sectors as a regular internal drive.
