geno888, I agree with you.
However, my question still stands. Let me rephrase the question.
How can I use True Image to clone my original OS drive (34Gb worth of data in a 80 Gb HDD # 1) to the external OS partition (50 Gb, one of 3 partitions) in a 640 Gb HDD # 2)?
The key here is the option is select "destination DISK" not partition or disk and partition.
I confused you with the original question.
PS. I enlarged the external OS drive to 150Gb, but still could not select it, even though True Image saw it.
If the answer is no, then does Clonezilla (or any other clone software) capable of such task?
