If it were me, I would install a fresh software load onto your new drive. It will run like the day you bought it, probably even better, depending on the drive you choose. If you are able to have 2 drives at once, you can copy over everything else, like applications and games, but if you have the disks, it's best to install them too. Incase you don't, put your system folder on a CD so you can always pull extensions from it. If you decide to just copy the entire contents, be sure to make your new disk bootable, but like I said, I don't recommend it. I believe the programs you are referring to are more back-up/emergency restore type of situations. I don't allow Nortons anything on PC's, but that's me. With Macs, it used to be a must have, but not so much anymore.
And I'm sure this goes without saying, be sure your bootable floppy has your CD drivers.
Off the subject note here: For those who have 1,000 fonts installed on your computer, be sure to use a Font Manager application such as Suitcase or ATM. This will allow you to turn them on and off when you want. Having that many in your system folder slows down your applications because it's forced to read each and every one when it launches and when you access them. You can keep them on your hard drive, just not in your system folder.
