    My MacBook Pro recently failed to boot into OSX and stuck on the Apple logo Loading screen.
    However I can boot into the Single User mode and I did some research on backing up files from there.
    My problem is, most of the files I don't want to lose are on the 2.5" HDD which I put in the SuperDrive space instead of the OSX drive, and I don't know how to use the commands to copy those files to another external HDD.

    Thanks!

    Attach the USB disk you plan to copy to then enter the command below at the command line and tell us what it says. It should list all mounted drives, then we can cobble together the correct command for you to copy files from the optical bay drive to the USB external drive.

    Code:
    diskutil list
    Make sure the external USB drive is formatted to Mac OS Extended.
