Don't keep a lot of movies on your hard drive, then? Or video games or large archives of work files?
That said, turning off hibernation or paging and then saving the encryption volume as pagefile.sys or hiberfile.sys wouldn't be a bad way to go.
But really, there's no way for anyone to say that a given file is a TC container: TC will try to decrypt any file you give it. The only way to know for certain that a file is an encrypted container is a) for it to be one and b) to give the correct passphrase to decrypt it.
That may be true for Truecrypt (and good if it is), not true for all other encryption tools; some, unfortunately, have identifiable headers (etc).
There are also ways you can combine a regular structured file (image, video, archive) with encryption such that on casual inspection it appears to be the normal file (and will be openable as such) but also contain encrypted data.
Given the tendency of manufacturers to have things like a recovery or diagnistics partition, etc, or having a moderate bit of unpartitioned space, you could also pretty easily hide an encrypted volume there...
