Truecrypt with non-system partitioned drives

Hi

Having thought about it for a long while I have finally got around to encrypting the system drive (incl data partition) on my laptop with Truecrypt.

My desktop has two drives. I have similarly encrypted the drive 0 which is the system drive. So far so good.

Now to secure the copy of my data that is mirrored from drive 0 to drive 1, I want to encrypt that too. Drive 1 has two partitions, the first for the pagefile for the system drive and the second for a copy of my data.

I am Running Win7 x64 and also have external backups for all my data.

1. How should I go about encrypting drive 1?
2. Do I need to remove the pagefile partition to encrypt the whole drive?
3. Do I understand correctly that this will wipe my data unlike the system drive encryption?
4. I would also like to continue to have the drive letter(s) for this drive to follow on as it now does from those on Drive 0. Is that possible?
5. When I eventually get there, if I want to mount drive 1 when the system is booted should I use the same or a different password to that for drive 0, or doesn't it matter?

If necessary I am willing to return the pagefile to the system drive, even if temporarily until I decide if I should install a dedicated smaller drive for the pagefile. I think securing my data should my PC walk out the door without me is more important.

Thank you in advance to anyone who may be able to clarify for me.
