Fine, thats all I meant there, that if you do that, and check that
the OS partition does boot fine and works fine, there is no real
need to do a binary compare.

> But binary compare of files requires accessing the files,

Not with the two non system partitions that you arent going to
change the size of, just a bit by bit compare is all you need to do
for a compare of those, given that you do a bit by bit clone of them.

Depends on what you mean by mounting.

Yes if you are doing that compare from a Linux live CD etc.

But not necessarily if you are doing the compare from something else
like a Win bootable CD etc.

I dont bother to do binary compares of cloned Win system
partitions, I just boot them and see if they work fine after
having the cloner do a verify after its just done the clone.

And I clone using what True Image calls its rescue CD which is
actually a bootable linux live CD, so there is no possibility that
Win itself will have changed the original system partition in any
way, because it isnt booted at the the time the cloning is done.

Thats one of its big advantages over Nortons which cant do it like that.

> Hey, I'm new to this stuff, so I could be way off...but how would you mount it?

You dont have to explicitly mount it if you boot a Win live CD and do the
file compare at that level. Not worth bothering with IMO but that approach
would work if you insist on doing a binary compare at the file level.

And cant be in your case with the partition you are changing the size of.

And that is correct. It just isnt possible to do a bit by bit copy if the size is different,
