Unplug the old drive from the system and install the new drive as the master. Use the Windows XP disc to format and install the operating system on the new hard drive.. Then install all drivers, software and updates to the new drive. Connect the old drive to the computer as the secondary drive and format it or do with it as you will.
I am interested where you got a 50GB SATA hard drive.. I've not seen them around here as everything here is MUCH larger than that.
As long as the motherboard and other hardware are the same, you shouldn't have validation issues by simply replacing the hard drive with a newer one. It's a legal option when an HD goes down, etc.. If you do have issues when validating, contact Microsoft and they should get it taken care of..
Hope this helps.
I'm running XP Pro on a 20GB SATA HD but having some registry issues so I want add a 50GB SATA HD and make it the master. I don't want to 'Ghost' the XP over due to the registry concerns. What is the best way to do it once I get the new drive formatted. Also, is there a Microsoft issue having the same copy of XP Pro on both drives initially?
If it makes any difference, I'm also upgrading the motherboard and adding memory.
