It is written bypassing a lot of the operating system and more directly to disk. A raw device and a block device is the same thing. Usually the user does not see much difference. But when the computer boots you can think of it as counting blocks in order along the disk to find the right one to decrypt and boot the kernel. sd0c is a character device. It is not written by blocks but through the operating system. If you write to a character device then, because you are not yet booted, the boot process cannot find the decryption blocks. My understanding is not the greatest but that is how I think of it to myself.
