I just purchased my first iMac and want to transfer my concert recordings from my pc formatted external hard drive to my iMac. How the heck do you do this? With about 300 gigs, I am not about to burn them onto a disk, thumbdrive or anything that takes that route. I am ok with pc commands, but Mac is oh so foreign to me. I have seen there are different ways to do this but I am lost. I need to connect my pc formatted external to the iMac, transfer them to the iMac then reformat the drive for the iMac. Any help in layman terms here would be appreciated! Karl
