My Book WD Smartware backup

I am trying to get the WD Smartware to backup my files on my new My Book. When I click on backup files a window pops up that gives two options - erase drive or cancel. In the Information tab - it says there is new software available. When I go to that it says the new software is NOT supported in OS C 10.4.11 (Tiger) which is what I have. What can I do?

Is the drive formatted to use on Mac? Is the Smartware version compatible with Mac?


Thanks, that was the problem. It was supposed to be formatted for the Mac but when I looked it was formatted for Windows NT so I changed it.
