Yeah, mylar balloons are those silver balloons used for parties and stuff. Seems mylar itself is transparent to EM radiation, but aluminized mylar provides some shielding apparently, and looks so cool with a Winnie the Pooh printed on the side. [bday]
I found this link for a shielding study: http://www.ieee.org/organizations/pu...0/penetrat.htm
It doesn't really answer questions in this thread, but has some curiousity value.
Aluminum reportedly provides no shielding, but steel will.
Thinking about it more, the logical reasons (at least to me) for that metal bracket on the drives is to 1) lock the drive into place, 2) cover the exposed wafer board stuff from electrostatic shock, 3) maybe shield the drive itself from EM radiation. (At this point, #2 seems the most likely purpose to me.) I'm open to discuss this though... anyone have a fun counterpoint?
