[Land-speed] OT: Win XP Pro vs Vista Question

[drmayf]

One of our local Pahrump associates has something he want to do with his 
laptop. And that is, dump VISTA and install XP Pro. But, he has a fear. 
He has a 200GB hard drive with stuff on it in the laptop and he is 
concerned that when he loads the XP Pro over Vista that XP won't 
recognize the drive size and he will have lost his data / information.  
Have any of you done this and if so, results? What should I pass along 
to him about doing this? I suggested that he transfer all the info to a 
USB external drive before messing with the installed drive.

Hhhheeeeellllllppppppp!
