BartPE: Restoring an image on a bigger drive, but keeping partitions size

Good evening everybody,

I've got to do some kind of project, and need a possibility to recover a partition in a very special way. I'm using BartPE with a Windows XP Professional as source.
To control the Acronis parts, I'd like to use the TrueImageCMD, controlled by some batch-scripts.

But back to my problem:
I've got an image, as example, from a disk like the following:

Total Disk Space: 80 GB
Partition C: 20 GB
Partition D: 20 GB
Unused space: 40 GB

This should be recovered on a newer and bigger harddisk, but partitions sizes shouldn't get scaled proportionaly. I don't know how to discribe it better, because my english isn't very good, I hope it is clearer with the following:

The new disk should look like this:

Total Size: 240 GB
Partition C: 20 GB
Partition D: 20 GB
Unused Space: 200 GB

What parameters do I have to add to the TrueImageCMD.exe command ?
Thanks a lot for your help !
