    I tried installing Snow Leopard. It installed correctly. But after initial restart, it hung and gave me the blue screen. I restarted several times but same result.

    Next, I booted from the install CD. Tried to install from there but install fails every time.

    Now I want to tranfer all my files to an external HD. I can view the files on this drive via Terminal. But I cannot write to it because it is read only for some reason. It also has a NTFS file system (i dont know if it matters).

    But I need help to mount this hd so I can read and write to it.

    Any ideas? Remember I only have access to Terminal and Disk Utility. I tried repairing disk for my local drive. Nothing. For my external HD the option to repair/verify disk is disabled.

    Which Mac are you installing it on? Where did you get the SL disk (what colour is it?)

    Don't external HDDs need be to be formatted for Mac OS?

    I am installing this on a Macbook Pro . The install CD is white. I got it from Apple.
