Drive swap

[3ee Dee]

Ok this is a little hard to explain...

I have 3 drives, a 160GB SATA, 120GB IDE, and a 160GB IDE. The 120GB IDE is an extra drive, the two 160's are the focus here.
What I want to do is clone the 160GB SATA over to the 120GB IDE, then I want to format the 160GB SATA and clone the 160GB IDE over to that SATA.
After that I want to format the 160GB IDE and clone what's now on the 120GB IDE over to the 160GB IDE.
This way, the contents of the 160GB IDE will now be on the 160GB SATA and vice versa and the 120GB IDE will go back to being an extra drive.

Is this possible? Am I making too much work for myself? Is there a simpler way of doing this?

Any help would be great. Thanks.

Simpler is to have a larger hard drive to hold everything...but nothing comes to mind for simpler and cheap (i.e. free). It's definitely possible, though I'd be curious as to why...

The reason why is I just got a new computer, it's running XP home on a 160GB SATA drive. My old computer is running XP pro on a 160GB IDE. I was hoping I could swap the drives without having to physically swap them. This way the new computer would retain it's new components but would have the XP pro and all my files from the old computer and the old computer would have the XP home and files from the new computer.

I guess it would be easier just to physically swap the drives right? Any tips on going that route?

How different is the hardware between the old and new computers? (Windows can get quite flaky when moving from one PC to another, since the hardware settings will be mixed up and it is easily confused.)
