Hello
Few things that you can do
1. Go out purcahse Norton's Ghost 2003
2. And just clone the old drive to the new drive
3. Depending on what drive you buy it does come with some software
4. Install the new drive and then set your old drive up as a slave
If you install the new drive load XP and all drivers and then setup
the old drive as a slave. You will have to jumper the drive correctly
and also in your system Bios make the cdrom the primary bootdevice
and boot your system up with the XP cdrom in, and just follow the
steps
Either way it's pretty simple and not hard at all
