I just bought a WD Hard Drive and am trying to get it to work on my MacBook. OSX: Leopard 10.5.8, and the hard drive model: My Passport Essential, 500 GB. I've been on the WD FAQ and Knowledge Base pages, but seem to be going around in circles. When I click on the WD SmartWare icon on my desktop I get the message "Unreadable WD SmartWare Drive"- Do I get this message because the hard drive is still formatted as NTFS and do I have to reformat to HFS or FAT32? Since I don't need it to work on windows, can I format the entire drive to HFS? If yes, how do I do that? I'm not that Mac savvy, and usually just muddle my way through any kind of problems that pop up. I don't understand what format I should use (HFS or FAT32- or if I can even format the hard drive to either). Any help, or explanation as to what either of those formats mean, would be helpful.
