I am really new to this backing up thing and it is really important please help me... I got an old imac '17(lamp) G4 800 mhz with 80GB bought late 2002...running Tiger(10.4) Which got an extremely important files that I need to keep. I just about a new macbook 13(non-firewire) which is intel and runs leopard. I am going to partition my new hard-drive 320 GB into 80-240, 80 GB for the backup and 240GB for any other use. I want to create a bootable hard-drive and I am going to use Disk Utility , Restore to make the source-destination method. I need these files to be accessed from mac+windows, and I would be able to boot from that hard-drive. What format shall I use to format the disk? Mac OS Extended or MS-DOS, other? There is an option for partition scheme, what shall I use? Apple Partition Map or Guid Partition Table? There are files in my Home directory which I would like to access in the backup, but my account is password secured, if I won't be able to boot from the hard-drive, will I be able to access the files going through the directories? plz help, do you recommend using other software?
