Turn off the computer and unplugg the power cord.
2Step TwoRemove the computer cover.
3Step ThreeTouch a metal part of the computer to ground yourself, or use a grounding strap. A kitchen table is a great place to work on a computer because of the flat space and the lack of static.
4Step FourLocate the ribbon cable connected to the existing hard drive.
5Step FiveChange the master/slave designation of the second hard drive (see Related eHows).
6Step SixConnect the second hard drive to the second connector on the cable (colored strip should be closest to the power cable). If the cable does not have a second connector, replace it with one that does, or use a second ribbon cable to attach the second hard drive to the motherboard (if a second drive port is available).
7Step SevenConnect an available power cable to the hard drive.
8Step EightInsert the hard drive into an available drive bay and secure with screws.
9Step NineReplace the computer cover.
Add Hard Drive to CMOS Setup
Steps
1Step OneStart the computer.
2Step TwoEnter the CMOS setup program (the system generally indicates which key to press), immediately after memory check.
3Step ThreeUse arrow keys to select Autodetect option (or comparable option for your computer) if it is available, and press Enter. If this option is not available, see step 5 to manually enter the drive parameters.
4Step FourIn the Autodetect screen, enter Y to select the default settings for each drive that is installed and bypass settings for uninstalled drives. The screen will return to the main setup screen. Continue to step 8.
5Step FiveTo manually enter drive parameters, select the setup screen that displays hard drive parameters (usually Standard or Main screen).
6Step SixUse the arrow keys to scroll through the list of drive parameters.
7Step SevenSelect the set of parameters that most closely represents your drive and does not exceed the drive volume (such as 2 GB) and press Enter.
8Step EightPress Enter or OK (or Esc if the other keys are not available) to accept the new setting.
9Step NineUse arrow keys to select Save and Exit setup and press Enter. The computer restarts, indicating the presence of the second drive. Your drive is ready.
