    I have successfully used SuperDuper to backup my main drive and use it as a startup drive. It's an external SeaGate FreeAgent Pro firewire. Unfortunately, Im having no luck with my new drive I purchased. This external is a SeaGate FreeAgent|Desk USB2.0. Specks below for both.

    Does going from FreeAgentPro to FreeAgent make a difference?

    I want to place Windows via Parallel's on the external.

    My computer is a MacPro 2x2.66 GHz Dual-Core Intel Xeon.

    I'm not clear on what you're attempting to do. Can you elaborate in more detail?

    Also, did you initialize the boot drive that's giving you trouble with a GUID partition table in Disk Utility?

    I believe you need firewire to boot, so that would explain why the USB wouldn;t work.

    +1 arronw1986. I just put in a new WD Blue 500 GB and was going to use SuperDuper to image my drive, however I have a new Unibody Macbook - so no Firewire. I read through the documentation, and it highly recommends a Firewire drive to work. Here's a quote from the doc,

    "On top of that, USB drives have a large number of limitations regarding speed and – even if USB 2.0 Hi-Speed rated – can slow down to USB 1.x speeds when used in conjunction with slower devices.

    So, if at all possible, please get a FireWire drive!"

    my experience

    I have a Unibody MacBook, and I backup to an external USB drive using SuperDuper without a problem, ONLY if the drive was plugged directly into one of the MacBooks USB ports, and NOT into a USB 2.0 powered hub. Not sure why this is the case.... just my observation. I also have the same issue with syncing my iPod Nano. (Probably an issue with the hub, but it seems like the new Leopard update is supposed to address USB issues). My external drive is a standard 500 GB PATA drive in a Metal Gear Box II usb/firewire case.

    EDIT: I have also been able to boot up the laptop from the external USB drive without any issues. On my old Powerbook G4, I used the same version of SuperDuper to back up to this same external drive using Firewire 400. The speed of backing up on Firewire 400 vs. USB 2 on my new computer felt about the same.
