I am currently building a P4 system, with a 1.6 GHz Processor, on an Asus P4S333 board with integrated Audio. So far I have the NIC, the VGA, modem, and 256 MB of DDR to start. (The board supports 2G of PC2700). This is the first PC I've ever built, so far it's all going pretty smoothly, but as it gets closer to crunch-time(actually plugging it in), I want to make sure it's all good to go.I have a 12X24X48(I think) CD-RW, your basic 3.5 floppy, and a Maxtor 20 Gig HDD ATA-100 @5400 RPM. I will change the HDD over to a 60 sooner or later, but right now my budget cuts that option off. My question is this: Can I remove all the hardware from the windows sytem, plug the drives into the new system, install the new board drivers and be good? Should I back up the entire drive(I'm not really sure how to do that), and then partition and format it? I'm as far as I'm ready to go with putting it together without some form of experienced feedback. I just need to know how to make sure my old drive works, and I still have all my data. Thanx.
