I can't help with the Norton 360 problem as I don't use it.
Although at one time I would always recommend Norton products, but then things started changing then I (and others) started to go off them.
However I do still, and always will use Norton Ghost, as I have found it to be one of the easiest and straight forward of the many similar type of programs that are around.
"
CLONE" the HDD is the proper term that is used when a HDD is Cloned over to a new HDD.
This creates a exact copy of one drive over to the other.
Providing the shop has not removed or altered any information on the old HDD (which they should not have) then it can still be done.
All you need to do is.
1. Find out who is the manufactures of one, or each of the drives. (Seagate/Maxtor most definitely have the software available to download)
2. Go to one of their web-sites, most of them have the software available for
free to "
Clone" the HDD to a new HDD. (you only need one download, the software will detect that you are using their software with at least one of their HDD and allow it to work)
3. Connect the old HDD to the PC as a slave. (You could temporarily disconnect and use the cable from your CD/DVD)
4. Run the software that you downloaded from either of the HDD manufacturers site.
As you say the HDD was getting noisy, then this would point towards a mechanical problem, not a software problem, so providing the drive runs, then the transfer should complete okay.
Obviously the length of time it will take depends on how much info is on the old HDD.
But is still does not take too long, maybe 10 to 20 minutes (depending on sizes etc).

For Seagate/Maxtor, you can download the "DiskWizard" software from here:-
