My Win95 machine has a 3.2Gig HD. It is sufficient for my needs but I came upon a free 364MB drive and I was going to slave it to the existing HD. When I opened the case I realized the CD-ROM drive is already slaved to the HD. The MB manual explains all the different combinations that are acceptable but gives no pro/cons. What do I gain or lose if I add the small HD as a secondary; if I make the CD-ROM secondary and slave the small drive; any other choices. I know I can get a lot more space for not much money, but I don't really need it and I am mostly trying to learn.
