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. How should I go about encrypting drive 1? Do I need to remove the pagefile partition to encrypt the whole drive? Do I understand correctly that this will wipe my data unlike the system drive encryption? 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? 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.
