Hello, I am making the switch this week from PC to mac. I have a couple of questions about different HD formating types. I currently have a 750GB NTSF hard drive that has all of my media files. I want to transfer that info over to a new 3TB RAID drive that I purchased for the new imac. first question: What is the default format for a MAC HD? Which type should I format the new RAID drive? This drive will more than likely only be hooked up to a mac, but if there is a type that can be used interchangeably (read/write) on pc and mac I dont mind using it. second question: After formating the new RAID mac drive, I can then transfer the data over from the NTSF drive. My understanding is that I can copy data over, but I can not write to the NTSF drive? This is fine with me. If however that is not the case, How would I go about transfering those files over to the new drive? Is there special software or drivers? Any tips/suggestions would be fantastic. Thanks!
