Hello, my name is Chris and I'm having trouble with available hard drive space. I have an 80 GB hard drive but according to my computer the hard drive is only 16 GB, I have been told I fix this problem through Computer Management, but have been unable to fix the problem, How can I get the computer to recognize the entire 80 GB's, as this is very frustrating, and I'm about to lose it and try a stick of dynamite. Any help would be appreciated. Thank you in advance. BTW I am using a genuine Windows Xp Professional OS.
