When I tried to make a FAT file system on a USB storage it turned out that mkfs.vfat is not on my system. I also tried to use GParted but it did not have support for FAT file system either. How can I restore the file system support? I do not remember clearly if I have used my new installation of Lenny to make a FAT file system or not. I think I did. So I am wondering how did it evaporate from my system if it was present.
