If you was to get a bus cable ( the cable that connects your HD to your motherboard) that had ten connectors on it you could have 10 HD's, all having diffrent name/letter.
This is what I needed to know thanks. My D drive was orginally a backup drive, but I never back up so I reformated it and now I can use it to install anything its the slave drive.
I was just concered because I didnt know if windows had to be installed in both, and concered that installing programs inthe D: drive will mess up the registry some how.
