6. The only way I could figure out how to clone my ihd was to create a partition that is the same size as my ihd, otherwise I will be wasting space if I clone to the entire 500GB eud?
My recollection of using clonezilla to clone partition to partition is that the partition you are cloning TO needs to be at least as large, preferably larger than the one you are cloning FROM. You should be able to get this info from documentation. If you are cloning a partition from one drive to another drive that will NOT include the master boot record so the drive you clone TO will NOT be bootable without some manual intervention. You might try cloning drive to drive instead of partition to partition as this will include the mbr. As I believe I indicated earlier, the mbr is NOT on any partition.
7. As far as my wife's PC, I am using Norton Ghost to clone her C drive to an image file. I guess that would be my only option in my case with my Ubuntu computer?
Clonezilla has the option to clone a drive or partition to an image file. In my minimal use of Clonezilla, I never used this method. When you refer to the "C drive" above, are you talking about the "C" partition or the whole drive. I know windows refers to partitions as drives because it assumes it gets the whole disk but...?
This doesn't really have anything to do with your problem but, when you use Norton Ghost, is it a program on your windows computer? When it is cloning the partition/drive, does it copy itself while it's running?
Is your 76GB hard drive in your Dell Dimension3000? Are you attaching the external 500GB drive to the Dell Dimension to do the cloning? Can you boot from an external drive with the Dell Dimension?
The simplest way to do what you want, basically to have a cloned backup, is to clone drive to drive so your master boot record is included.
You could create the partition and format it (80GB) on the external drive, clone the partition to the external and then install Grub to the mbr of the external drive so that it can boot on its own. Installing Grub is a very simple thing.
I'll see if I can find my Clonezilla CD and look at some of the documentation. Post back if you have more questions.
I just looked at your SuperDuper link. That's similar to cloning an image on Clonezilla.
