. This increase in Virtual Memory (PF) is normal and good. XP automatically sets the PF size to 1.5 times the amount of actual RAM. It saw that RAM was increased, so it made the adjustment.
Nice upgrade ! When you say you are going to swap over to the new drive, do you mean that you want to move XP over to it, or just your documents, photos, music, etc. ? If you want to move XP then you will either have to reinstall XP onto the new drive or else use a drive "cloning" technique to do this. You can't just simply copy iy over.
After a clone is done you need to configure the new XP installation so that the BIOS knows to boot off of it rather than off the old drive. This is called "setting the boot device order in the BIOS" and "setting the active partition". Google is you friend.
You can "clone" the original hard drive to the new one if the original is still in good working order. You must be able to log into Windows, or at least into Safe Mode. This will save you XP installation including the Registry, programs and settings.
