This is not really accurate. FAT is the old-fashioned DOS format with 8.3 filenames (e.g. notenoug.ext). Vfat is the same thing with Microsoft's extensions to allow it to store long Unicode filenames. Vfat should always be mountable as FAT. Pure FAT needs upgrading to be mountable as Vfat, but: * there are very few pure FAT filesystems around these days: any modern tool will automatically create VFAT, without asking. * When you put a FAT floppy in a Win95 and up machine, Windows would silently change it to the vfat format. It was still supposed to work as a FAT disk on earlier MS OSes. (The DOS world being what it was, this did break a number of "copy protection" routines...) * Anything over 4 GB *has* to be a FAT32 partition. This postdates Vfat, so you can rely on it having support for long filenames. But it still supports 8.3-only mode, for use in the DOS 7.1 that underlies Win98 and Win95 OSR2. (Those extensions are thoroughly weird: check the end of Documentation/filesystems/vfat in Linux source code for more details). Nicholas (the original poster): can you see this disk through WinXP? Are there any files on the disk? It sounds as though you've defined the partition through fdisk. There is support in the PC partition format for filesystem types: here you can say that the partition *will* have a vfat filesystem in the future. I'm just not convinced that you've formatted the partition (Windows terminology) = put a filesystem on in (Unix terminology). James. Trivia time: which OS will create and install on 4 GB FAT16 partitions? -- E-mail address: james | The grass is always greener on the other side of @westexe.demon.co.uk | the sunglasses.
