How would I set up my old hard drive?

You can hook it up in any position(master slave) to the secondary controller or primary if your main drive is SATA.

I'm a little confused on what you have set up. It goes this way. Computer has hard drive. Usually the jumpers are set to master or network, If you add another hard drive, you can not have 2 masters. So, jumpers are used to set the pins to allow the computer to boot from the master hard drive and then see the second one as a slave. Not an OS system. So you can have another drive letter assigned to the second hard drive and copy files between them, but only one is the master Look at the drive you want to be the slave, usually somewhere on there is shows where and what position to put the jumpers on

Set the jumper on the old drive to slave. Be sure that the bootable HD is set to master (not cable select).

I would hook up the old drive on the same IDE cable as the newer drive.

THATS IT!!

Since it is a new computer chances are you have SATA hard drive so hook your old drive in the only IDE cable in any potition by seting the jumpers

All you have to do to connect your old hard drive to your pc hook it up to the same flat cable that runs your dvd player on your new PC. First turned off your pc and unplug the power, set your old hard drive's jumper to the master settings and dvd player's jumper to slave setting. Usually your flat cable has 3 terminals: both end & at the center. For sure one of the ends of it is connected to your motherboard and make sure the other end is connected to your old hard drive. At the center terminal of your flat cable must be connected to your dvd rom player. Turn on your pc, during reboot tap your keyboard continuously to go to system setup (for example sometimes you will see "press del to setup" or you will see other keyboard command to go to setup while your computer reboots. If you have entered already to system setup utility try to find IDE HDD AUTO DETECTION & press enter. You will find "select primary master", "primary slave", "secondary master", and "secondary slave" press Y for YES in your keyboard and press enter to all of these primary & secondary. (You can go back to HDD or HARD DISK detection if you accidentally made a wrong selection like hitting N or NO in your keyboard). Select Save & Exit setup and press enter. Save to CMOS or SYSTEM SETUP? Press Y for YES in your keyboard and press enter. Wait to reboot your pc, when you are already in WIndows check your my computer icon and check your old hard disk.

well the drive has to be on the same cable as the new hard drive and make sure it is set as a slave
