I have mounted a fat32 partition 7dev/hda2 on /mnt/data with the vfat option and added an entry in /etc/fstab with auto option. The folder /mnt/data was created with default umask and has 755 permissions. In order to have the possibility to write on that disk when I login as "nepote" (that is my usual identity and is part of the group "root") i logged in as root and: chmod 775 /mnt/data -R the command returns a list off "you don't have enough permissions (requested 775, was 755)" ?????????
