Right,
The best way to do this, is to install one of the sata drives, boot into windows, let it plug and play, create a partition on it. And then copy your documents and stuff that you want off your ide hard drive.
Then, disconnect both drives, and plug in your other sata drive and do a fresh install of windows xp. You will need the sata driver disk that came with your motherboard to do this. Once XP is installed, connect your other sata drive and let windows install it.
Once that is done, connect up your IDE hard drive, boot into the BIOS and change 1st boot device to the SATA drive that has windows on it. Then, format the IDE drive and keep it as a backup drive.
You could use Norton Ghost to copy the drive image from the IDE to the SATA drive if you really wanted to, but I doubt it would be 100% successful.
