I have just purchased a 500GB My Passport Essential and plugged in as per user manual. When I clicked on the Smartware icon as instructed I get a message stating that there is no writable smartware partition on this drive. It then suggests that I check it is formatted for my operating system (Mac OS X on a macbook) and unlock the drive. The drive is unlocked.
How do I either reformat the drive for Mac OS (it was supposedly preformatted for Mac) or repartition the drive?
