Arin Bennett, manager of the Digital Media Lab, also suggested this method Jan 2010, but we would have to check to see 1) if a Mac could read the NTFS section of the hard drive and 2) if a Windows machine could read the FAT32 section:
You could partition the free space on your NTFS harddrive as FAT32 which would allow you to save your processed images and read/write on both PC and Mac. That is, you read the images off the NTFS partition and write the new images to the FAT32 volume.
