So I built a computer for my mom and my dad and they said they still wanted all of the stuff from their old hard drive. I decided that I'd just set it up as a slave. ( it has windows 2000 installed ) and their new hard drive has windows XP. The thing is though, on the hard drives themselves there isn't any slave/master jumper information. It says on my new hard drive ( sata ), that it doesn't require slave/master. But, my parents old hard drive, it's a 20 gig hard drive, isn't SATA and there is no jumper information on there either. So if I have just my new one hooked up it runs xp and when I have both hooked up it runs 2000 but I guess since it detected the hardware is different it doesn't really work. I'd prefer if I could get it to boot off my new hard drive and just use the old one as a slave but I have no clue how to do this now. No idea how I'm supposed to arrange the jumpers, if I'm supposed to arrange the jumpers. Gah! Help!
