Help! Still can't back up MacBook on Hammer Firewire

[k8conant]

I'm a newcomer to SuperDuper! and haven't yet been able to successfully backup my MacBook (74.5GB = 66 GB on MacBook HD partition and 8 GB on Untitled Windows XP partition) to my Hammer external drive (320GB shown as 298.1 in Disk Uility). I have the Hammer formatted GPT (GUID Partition Table) and 2 partitions right now (Intel_Boot @ 148.92GB HFS+ and PPC_Boot @ 148.73GM HFS+[for Mac Mini G4 running Tiger later]).

I've tried for days to get a full backup of "MacBook HD" and it hangs no matter what options I use. I see in the discussions that there have been problems with OS X 10.4.8. My backups have stopped at different points from 1.7GB to ~6GB.

Detailed instructions would be appreciated. I've verfified the disks repeatedly, repartitioned the Hammer, prayed, cursed, whatever.

Help!
