Any Software for Hiding Partitions & protecting data ?

Hi,

I want to ship a hard drive with sensitive data ( Not Porn ) overseas.
Drive has win -7 ( 64 bit )

Is there a software that would Hide individual Partitions & protect it with a Password ?

OR Any other ideas ?

Any help would be highly appreciated.

Thanks

 

off the top of my head, windows 7 ultimate (and business?) have bitlocker.

I'm not too familiar with anything else, just my .02 (well just 1 cent)
