    Red face Best File System Format for Multi-OS use


    I just bought a USB enclosure for an existing 160GB hard drive I have and planned to use it as a backup, on my dual-boot Vista/Ubuntu box, as well as my wife's Mac OS X notebook.

    The disk was already formatted as NTFS but just for the hell of it I reformatted it again in NTFS directly from Windows to make sure all was "clean". I then did everything I could to modify the Windows permissions to make the drive completely "open", with full RWX capabilities for all users.

    Ubuntu and OS X can both see and read the drive but not write to it... which defeats my original intention altogether.

    I know there are tons of file formats out there... NTFS, FAT, some Linux formats, etc. I'm not looking for anything super secure, I just want something that will allow me read, write, and execute permissions for a single 160GB partition that will work with all 3 OS's.

    So... now that I've written this quick novella, any suggestions?

    Thanks so much!

    iirc, You can't format a FAT32 bigger than 32gb from windows but you can use linux or another OS to make a large FAT32 partition. I don't know if Vista removed this limitation or not.

    ntfs-3g supposedly provides r/w support for ntfs from linux. I have no idea about Mac OS. FAT32 is the most compatible choice. Oh, I believe FAT32 restricts file size to a max 4gb.
