    Hi i just bought a new harddisk. (http://wdc.com/en/products/Products.asp?DriveID=324 the 500 GB edition)
    I run leopard on the intern harddisk.

    But when i insert the Tiger install disk and choose to install on my Tiger partition on my extern harddisk it just says that this disk is not able to boot from or something.
    How can i change it so i can install tiger on it?

    First off, that's a USB drive, which, while it will be able to boot an Intel Mac, will be oppressively slow, so I don't recommend it. You're far better off with FireWire.

    Regardless, though, you'll have to format the disk as HFS+ to be able to install OS X on it. You can do that from Disk Utility either booted from your internal drive or booted from the Tiger DVD.

    Okay then im just going to use my intern harddisk to all the systems and put all the files in the extern.
