I am having Dell precision m4500 laptop. I am using this laptop since last 2 years. The optical drive of this laptop is not working properly. The problem is that there are many bad sectors in the optical drive. My engineer told me that you can replace your optical drive with the hard drive bay. I want to replace my optical drive with hard drive bay. How can I replace and install the drive and which drive will it be perfect for my Dell precision m4500 laptop?
