The following tip is a step by step instruction guide to replace your IDE Hard drive.
Before you start working with any of the Computer hardware, you need tobe sure that your computer is switched off. Also, unplug your computerfrom all cables.
Once you are done with the above steps, you need to open your computercase at the side on which the motherboard is not situated. This isusually done by unscrewing the 2 screws at the back of the panel.
Now slide away the panel gently and expose the inside of your computer.
You will be able to see a clear view of the hard drive. You will also be able to see the screws which holds the hard drive in place. There is usually only 2 screws, but if you unscrew the 2 screws and the hard drive is still attached to the case, you need to unscrew the other side panel as well to unscrew these other 2 screw.
When you are done unscrewing the hard drive, you can gently remove it from the hard drive slot.
Now, unplug the cables from the hard drive. you will just plug this cables back into the new hard drive. Just remember, if you plug in the new hard drive, you need to check the jumper settings. If this is the only drive, and you want to install the Operating system on this drive, it needs to be set to primary. Otherwise, to secondary.
After you have checked the jumper settings, you can plug back the Hard drive and just reverse the previous steps.
I really hope this can steer you in the right directions.
