This damn drive is GARBAGE!!
First off, it comes with a standard USB cable and no external power. My [awesome] Maxtor One Touch has a USB Y-cable so two USB ports can power the drive.
At first the Passport worked, but needed a little cable shaking to get the computer to recognize the drive, but after loading 30GB worth of data it's not recognizing it at all. Worse part is that WD's diagnostic software says that it works fine. They won't honor any part of the warranty if the diagnostic comes back good
