Hi guys, I hear that if I stuck a windows (NTFS) external HDD (2TB) to the iMac it will only read the data? I have a SEAGATE 2TB external HDD (USB2) full of videos and would at some point like to transfer to a larger HDD (3TB) but utilizing the latest thunderbolt tech (when it arrives) and im assuming that mac HDD would be FAT32? Would there be a problem if I transfered the NTFS 2TB USB2 HDD to the Thunderbolt FAT32 HDD I got, seeing as it only write from one to another? or am I missing something here? Help would be appreciated. How would I go about this?
