hey, I have a solution for questions
Install Hard Drive
Step1
Turn off the computer and unplugg the power cord.
Step2
Remove the computer cover.
Step3
Touch 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.
Step4
Locate the ribbon cable connected to the existing hard drive.
Step5
Change the master/slave designation of the second hard drive
Step6
Connect 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).
Step7
Connect an available power cable to the hard drive.
