Is there a way I can format my external hard drive to have a FAT32 partition as well as a MAC OS extended partition? I've snooped around and can't seem to figure out a way to do this with disk utility. Not sure if this matters much but I have about 200 gigabytes (of 500) used as it is already formatted to mac. I want to shrink this partition and use 32gig free space for a FAT 32 partition. I'm also considering a NTFS partition and then getting another external for time machine. Hope this is sensible.
