    I have a 640GB external USB hard drive that I use for time machine currently. I would like to go in and add a partition to load movies to and plug it into my PS3. Can I use disk utility to create a new partition without erasing the stuff already on the disk?

    And then is it possible to format a partition larger than 32GB as FAT?

    Yes, you should be able to add a new partition using Disk Utility without erasing the existing one.

    Just choose the drive, then click the + button on the partition tab.

    Ok, thanks. I was playing around and saw that option. I just wanted to make sure I wasn't going to loose anything, just to be safe.

    If there is anything on it other than the TM backups, I would back that up separately first - just in case.
