We have 2 Macs and 3 PCS. I am looking to connect my 1.5 TB drive (currently formatted PC NTFS) to my TimeCapsule and use it as a common external drive. I do not want to format the drive FAT32 because I do not want to be limited to 4GB files. So MacDrive seems like a good way to go about doing what I need to do. The thing that confuses me is do I need the Mac or PC version of MacDrive or both? Do I need Macdrive to read the drive, in which case I would think I need the mac version, OR do I need the Windows version to format the external drive. I would greatly appreciate anyone who can clear this up.
