Hi folks, I have a quick questions about partitioning my 1TB external HDD. Currently, there's a 32GB FAT32 partition and the rest is HFS+. I've got about 700GB free on my HFS+ partition...is there a way to repartition this space into an NTFS partition of about 300GB, for a total of 3 partitions, without loosing all my data? I know on the windows side, there's apps like Partition Magic that let you do this. Anything similar for OS X?

Apparently under Leopard you can resize a partition as long as you don't change where it starts, so you should be able to shrink your 300 GB partition and then create new partitions afterward.

I have a question about this too.

I have an external drive with two partitions, one is my time machine backup and the other partition is blank.

I'd like to reformat the blank partition 2 and set it up as a bootable drive.

Can I do this without erasing my time machine backup on partition 1?

Disk Utility can do what you ask, but please be aware that with any partitioning operation there is a risk of data loss.
