No, that can't be done in Vista. But you can move a great deal of the content of the c:-drive (your Documents folder and everything it contains and the other subfolders of the rootfolder you created yourself) to the d:-drive and start using that.
Windows and Users (except for the Documents part) can't be moved. Program Files can't be moved, but you can install most (not all!) programs onto the d:-drive also.
To move your Documents folder, right click and find the Move command in it's properties.

I have a sony vaio laptop computer running windows vista home premium service pack 2. it has two physical hard drives that are identical (toshiba mk1637gsx). the primary drive is almost full. I would like to merge the two physical drives into one without reformating my primary drive to create more space for programs. Is this possible? If so please give me instructions on how to merge the drives into one. Your help in this matter would be much appreciated.
thanks.
