Hi all, I was going to start the process of replacing the old hard drive in my Powerbook G4 1.67 today, and started looking through the SuperDuper! instructions and noticed that it mentioned the following: USB drives cannot be used as a startup drive for PowerPC based Macintoshes, regardless of the program used. 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! Now, I have no experience with replacing/copying HDDs at all, so the terminology of a Startup drive on a laptop has me confused. What I had planned on doing is using SuperDuper! to clone my current HDD to its replacement in an external ATA case, via USB, as the case I purchased doesn't have FireWire. Now, since I plan on marking this new drive as bootable so I can just swap it out, am I SOL because I don't have FireWire, or am I only SOL if I planned on using the drive as an external startup disk? Hopefully the above makes sense. I really appreciate your responses, and any other suggestions you may have for a first-timer doing this seemingly daunting task.
