Hi guys, I'm just a regular user so please dont judge me for any question you consider obvious. my system is a 1.2 ghz Athlon/512 mg ram/XP/ATI 64 meg video/20 gb HD (broken into two partition 12&8 aprox) 5400 rpm/second drive 3 gb. I just got a new 40 gb HD 7200 rpm, my idea is move my OS from partition 1 on 20GB HD into the new faster drive, after this reformat that partition and use it for storage. How can I do this ?, I'm thinking getting rid of the 3 GB HD and use this conection for the new one, after having these two drive connected How do I move the files?? do I need any aditional app for this task? and wich one?. When this is completed and i have a copy of my OS into the new drive, I'll change positions of master/slave on the drives and reboot, but how do I know where I'm booting from? If a made a copy of C:/ into de new hard drive now I have 2 drives with the same name partitons .... How will XP behave when the new drive is plugged in, and, to finish how do I reformat the old C:/ partition? Thanks for any help, please share your XP-eriences on this matter.
