    i have a 320gb external hard drive and was wondering if i could partition it so i could use it just as an external hard drive on one partition, but have time machine on the other partition. i just recently got my frist mac, which is a macbook, and i love it. i would appreciate it if someone could tell how to do this if it is possible. thank you :)

    Disk Utility can do it. I'm running Tiger so I apologize for that.

    There's really no reason to partition your external HD. All of your time machine backups are kept in a folder on the HD called backups.backdup or something similar.

    Then you have the whole HD to store whatever you need to and Time Machine won't erase those files - It will simply just start to erase your oldest backups

    It depends on your needs.

    I understand Time Machine deletes when the drive fills up, but once the drive fills up you won't have room, in case you need it for something.

    Having partitions ensures that there's always extra room.

    I split a 250 GB drive into 3 partitions.

    1 for PowerBook Time Machine
    1 for iBook Time Machine
    1 for Video Projects

    If I remember correctly:

    -Go into Disk Utility > Partitions
    -Change the Volume Scheme from current to # of partitions
    -Click and Drag to resize partitions
    -Click Option to make sure each partition is set up for Intel Macs, PPC Macs or windows.

    This helped a lot. I have a question though. I have some stuff already on my HDD and if i partition my HDD (because i want part of it for time machine and part to work with windows and mac) will it erase my HDD?

    Yes. Anytime you create a new or change a partition it will erase anything on all partitions on that hard rive.
