If I take a hard drive and partition half of it as NTFS and install Win XP on it using Bootcamp and partition half of it as FAT32 and leave it as an empty space, would I be able to copy files to and from the FAT32 partition when running either Win XP or OSX so that the files could be shared? Can you create partitions on a drive of different formats such as NTFS, FAT32 and also the Mac's format (I forget the name of it)? Could they be made bootable partitions? I would like to partition a drive into thirds, with one third as FAT32, one as NTFS and one as the Mac hd format, and make the NTFS and the Mac hd format partitions bootable. I would install Win XP on the NTFS partition and use the Mac hd partition to hold a bootable backup clone of my Mac OSX. The FAT 32 partition would just be used as a sharing space for files created in both OSs. Thanks for any advice.
