    Hi,
    I'm wanting to make the jump to Lion, but before i do this, i want to create a boot drive with my current settings and files for snow leopard.
    I have a partitioned external Firewire 800 drive (i only needed 240GB max, and i had other files on the external that i wanted to keep) and i have used Carbon Copy Cloner to copy the entire contents of my internal over to the partition.
    When i turn on the system with the external plugged in, i hold down alt (option) and the list comes up with only my main boot drive and bootcamp. I can't see the firewire drive.
    What do i need to do?
    Please help

    I think you need to make the partition bootable. Go into Disk Utility and make that partiotion a GUID partion. You can do this under options on the Partition tab. Then just use carbon copy cloner or my personal favorite super duper. I did this with a usb thumb drive and super duper and it showed up when I held onto the option key while booting up my mac. Hope this helps!

    The whole hard drive is GUID Partition scheme, and yet it still doesn't show up... Bit annoying

    ----------

    Should i be backing up the entire disk or making a disk image? I've tried both, but it would help if i was certain which one to use as it takes 45 minutes to copy everything

    Ok, problem solved.
    I am yet to find out exactly what the problem was, but i just wiped the partition and backed up the primary drive again and noticed it appeared on my startup disk list, then when i restarted holding option it came up straight away along with the bootcamp and primary drive. So, yeah, it works now and i didn't change anything. I just re-did exactly what i did before and it works. Technology...
