Writing to File on External SDCard

I'm trying to write to a file on the external SDcard with an app, but it remains with permissions of 771. (execute only for Others) In Termianl I su and chmod 777 file, but it remains at 771.

This seems to mean the OS is preventing this file from being world writeable. Each app is run by a different user so I can't know which user will try to write at a given time. As root I can 'touch' new files all day, but I can't set them world-writeable.

What is preventing me from doing this?
