i have TrueCrypt partition, when i insert it in OS X, it always prompt me to initialize the hard disk. is there a way to prevent os x from detecting uninitialize hard disk?

[UPDATE]

by the way, as Truecrypt suggested while i'm in Windows, i must make partitions so the os won't detect the hard drive as uninitialized. Windows respected that the drive already have contents by the mere fact that it has partitions, while OS X thinks that it is still uninitialized. i think OS X is trying to be smart by detecting if each partition has a valid filesystem id/marker
