Hope this is the last time I am going to bother you. I have installed my new disc, a 160 GB SATA II, partitioned it and load my OS, Windows XP. My old drive, 40GB ATA is still in a good condition and can be used. What would happen if I install my old drive just as it is together with the new one to transfer files, settings, etc? If that would not work, what changes should I make in the BIOS to make it work? I've made a disc with XP's transfer setting wizard that I can use but I am just curious to know if there is not a better way. Thanx so much for your advice, it is really appreciated and I think all of us learn a little bit as time goes on, even the Masters. Have a nice day.
