Hard drive manufactures are toying with the idea of making it impossible to download
previously stored material.
IMO maybe that would be possible to be achieved but it would be impossible to be implemented.
Every day 5-10 files are e-mailed to me and they are either .doc(microsoft word), gif,,jpg(pictures), or dwg(autocad ). These are previously saved files that I download in my computer , if I am not able to save them
the whole idea of e-mail/internet/intranet goes by the way side.
It would be much easier for microsoft to develop software code that gives the user the option to assign an attribute to a file in case he/she does not want a particular file to be saved in another machine instead of the hard-drive not to accept it.
Maybe that was another of Disneys ideas to protect its intellectual properties and another proof that they do not understand that technology runs in the speed of light and not the speed of the turtle.
