I'm aware of 2 things that would break this: - The filesystem is mounted with the noexec flag set. - For filesystems that don't have permissions natively (like FAT), the filesystem is mounted with a umask that prevents the execute bit from being set. You could check both of these things in /proc/mounts when the filesystem is mounted. How to fix it depends on what is actually mounting the filesystem in the first place. How do you access the drive after you plug it in?
