My grandma needed more harddrive space on her pc so I installed an 80 gb harddrive on her pc. Right now it's just her slave drive. Her c harddrive is only 20gb, so could I just copy everything on that harddrive to the 80gb and make that the master hard drive and the old one the slave? Or would that cause problems? I want to do this so she can continue saving files to her c harddrive instead of a different harddrive.
