    Everytime I try to install Snow Leopard on my 15'' 2006 MacBook pro it will get half way through the installation and it will fail and give me the error could not copy necessary support files. I tried two different Snow Leopard disks. Im after installing snow leopard before but I had to erase my hard drive and install again.
    Btw for the people thats going to tell me to erase with all zeros too see if it gives me a error. It dont, so I do think my hard drive is still fine.
    Im using a external keyboard because my other keyboard got water damaged if that would cause any problems. Also I have the original ram installed

    It could be a bad drive. If you used two different disks and you get the same error, then it must be the destination drive.

    Start up Disk Utility (found in the Tools menu) of your install disk to see if finds/fixes any errors.
