I have an older computer with two hard drives attached. The master is a 1.6 gig and the slave is 6 gig. Regrettably all of my programs are on the smaller drive and hardly anything at all on the larger one. Do I need to install an operating system on the second drive in order to save programs on it(like mcafee,office,etc.). while on the subject is there any way to swap everything from smaller to larger hard drive. I haven't been able to find any solutions that didn't cost 70 or 80 bucks(since the computer is'nt even worth a couple hundred). I was also toying of the idea of opening the desktop and removing main drive and replacing with the larger drive and reinstalling all software. Any suggestions?
