Ok, so now that I got Leopard installed and running on my Macbook, I want to set up time machine. But the thing is when I turn on my external HD it is not listed on the picking drives list thing for time machine. So how can I make this work. I have 3 partitions on my external right now. I have a 300, 100 and 70 gb pieces. Right now the 300 and 70 gb pices are formatted as NTFS. And the left over 100 is for Time Machine. How do I make it so that my comp will recognize it and use that 100 gb?
