This is only an idea (ie. a guess :-) based on something I read in the hardware
manual that I received with my LaCie 40M quantum external drive.

Apparently, there is some kind of "ground" or "static strap" of some kind
inside the drive that can produce a "whine". Whether or not this is the whine
that you are hearing, I havn't a clue but according the breif explanation in my
manual, the fix involves slightly bending this strap (or what ever).

Anyway, you DID only ask for an IDEA! :-) Hope this one helps.
