How to Hide Truecrypt encrypted partitions in every computer

[Wooops]

I know you can do the registry/windows disk management tweak
http://www.raymond.cc/blog/archives/2008/07/27/how-to-easily-hide-drive-letters-or-partitions-from-appearing-in-my-computer/
but that works only on that computer.

How can I hide the encrypted drives in all the computers I plug my external hard drive?

Any way of doing it or simply it´s not posible?

Thanks

PS I don´t care editing the partition headers.

Sorry I've never even heard of this question before. Hope that Raymond or someone experienced replies with the answer.

@optimus prime

how did you do it? :O

@Amature Programmer

No problem. Thanks anyway

OK, I guess there´s no workaround then...
