I've had this external hard drive for a while now, using it on my PC. Now that I have an Apple, I want to use it on that. It is formatted for PC and on this Apple, it is read only. I'm pretty sure that means I have to format it to Apple, right? I called Apple and they said they don't support that sort of stuff, I can't find the phone number to the hard drive manufacturor and I now turn to you for help. How can I make the HD read and writeable on my Apple? I don't care if it becomes useless for PC. Thankyou!
