I just read the article:
I can't boot from my SuperDuper! copy. Why?

I have a Nexto CF Ultra, which is a Portable Store Device with a Compact Flash slot. The device is an enclosure for 2.5" HHD's. The Nexto features a Oxford chipset so I should be able to boot from Firewire.
The file sytem format to be able to read the memory cards is FAT32, so I need one partition FAT32 and another partition in HFS+ for my SuperDuper! backup.
My computer is a PowerBook G4 (Power PC) with Mac OSX 10.4.11
First I tried to partition the drive from OSX with the Disk Utility but came to the conclusion that with my disk in FAT32 (needed otherwise I can't use the Compact Flash function) I can only format my volumes in FAT32. No options to format HFS+
So I found a way to do it from Unix with the Terminal app.
My command was:
fdisk -e /dev/rdisk1
initially fdisk told me:
fdisk: could not open MBR file /usr/standalone/i386/boot0: No such file or directory
I went along with partitioning with fdisk creating a FAT32 and HFS+ partition (maintaining the parent disk FAT32)
When writing out the edit fdisk told me:
Writing MBR at offset 0.
According to the article:
"Macs cannot start up from volumes that are partitioned with Master Boot Record, regardless of chip. So, make sure your external drives are partitioned with APM (if you want them to work with both Intel and Power PC Macs) or GUID (if you're only working with Intel)."
So this must be the problem right?
How can I partition my disk with APM? Any information?
Another thing that I really need to know, since I can't check if my backup booting from the Nexto.. Can I reinstall my backup with the C key to the Tiger Disk and use Disk Utility to erase and reinstall my OS?
