I have an HP Pavilion N5310 laptop running XP OS. It has a 10 G hard drive as my local C drive and I am using an external Maxtor 100 G hard drive for overload. I continually run out of space on my local dive C so I would like (if possible) to use my 100 G hard drive as my Local drive. How do I do this? At this time I can not afford a new computer and so this is my only alternative. Can someone please help me?
