I have a 500 GB Passport with firewire. I usually keep it plugged into my mac book pro. I went to download some files to it today but the drive was not running. I’ve unplugged and plugged the drive in a couple of times with no luck. the drive makes a hum and then is quiet, no lights come on. Did I fry my hard drive? Is there ANY WAY to retreive the data on that drive? I am crossing my fingers for some good news. I have the passport unplugged currently.
