Yeah, but poc was right in that if you have an image of the disk, you will know that there's an encrypted partition there, and you can get a court order to force the password. Since you have no fourth amamendment rights upon entry to the country at the moment, the government does not need a warrant to seize your laptop and/or make an image of it to play with at one's leisure. Of course, even having a good password is no guarantee any more.
In the US you probably can't be ordered to provide your password. If you are transiting the border it is probably best not to take sensitive data with you. It will normally be safer to use the internet to transfer the data after you have crossed the border.
It is very much a grey area, but it may not really matter. They can always keep your data and analyse later; more importantly refusal to divulge passwords could be grounds for denial of entry (only for non-US citizens).
