I have a Lacie 40Gb usb external drive. Its been formatted to Fat 32 as i was using it to transfer files with a windows machine. I now want to use it exclusively with mac but i cant seem to format it to HFS+. Whenever i mount it to my Powerbook G4 and try to format it it only ever offers the MS-DOS File System. Can anyone tell me why it is not offering my mac format options? Thanks.
