I'm in a bit of a predicament. My college have updated their computers to Windows Vista 64-bit. I have an Aluminium iMac running 10.5.2 at home and I need to constantly transfer large files (5GB) that I am working on back and forth from college on an external Drive I have. I would have used MacDrive, but it doesn't support Vista x64. My teacher says that he read somewhere that Leopard can read and write to NTFS. Is this true? If so, how do I format a Drive so that Vista and Leopard can read and write to it?
