I'm rather baffled by this one.
I am using Windows Vista and am running truecrypt version 6.2a system encryption with pre-boot authentication for the C: only. I have a D: which is not encrypted.
Using knoppix I have booted my machine into Linux and used the
dd command to copy byte-by-byte the encrypted C: drive onto a USB drive partition of the same block size.
Booting back into Windows Vista and using the truecrypt GUI, I have selected my USB drive partition as the volume to mount (
\Device\Harddisk1\Partition2). I then have tried any combination of options including "Mount as read-only", "Use backup header", and "Mount partition using system encryption without pre-boot authentication". I expected this last option to work. However I enter my password and every time I get the message: "Incorrect password or not a TrueCrypt volume".
- has anyone successfully made a true partition copy of their encrypted system drive and subsequently mounted it using the TrueCrypt GUI?
- do I need to mount using a keyfile instead of the password I use during boot?
- do I need to back up the boot partition as well as the C: drive partition?
- is there another way of achieving this goal of backing up and mounting my system partition?
