Hey everybody! So, I'd like to get this very popular drive: http://www.amazon.com/Passport-Port...1355714611&sr=1-1&keywords=wd+my+passport+2tb But technically these are for Windows, and they make a Mac version here: http://www.amazon.com/Passport-Port...1355714611&sr=1-3&keywords=wd+my+passport+2tb I'd rather get the black version, and I read some of the reviews stating that you can just reformat the Windows version and it will work fine for Mac. While I'm sure I could get it to mount, would there be any possible performance issues by doing this? In other words, is there any reason to buy the Mac version, or are they identical, but just come formatted differently? Thanks!
