I just got myself an external hard drive and now I wonder what file system I should use on it because I have a Macbook and a Desktop PC w/ Windws Vista and Ubuntu Linux. It came formatted with NTFS. I primarily use Mac OSX. I just keep Windows for games and Linux for college stuff. 1) stick with NTFS and use MacFuse on the Mac and the equivalent in Linux 2) format it to HFS+ given there is a program that makes it accessible under Windows Vista 3) format it to HFS+ and make it accessible over my network Which solution is the best or is there another possibility?
