No... I'm not referring to your size or weight. File Allocation Table (FAT) is a file system created by M$ in 1977 and is the predecessor of New Technology File System (NTFS). FAT is still commonly used on storage devices (eg. memory cards, external drives) because Mac OS X does not recognise NTFS.
This is the very reason that I wanted to reformat my external drive as FAT32. Hmmmmm... strange??? No FAT32 option? Aaaaaah...turns out that one of the limitations of FAT32 is that it can't be used on partitions larger than 32GB Windows OSs (after Windows 2000) have a built-in mechanism that prevents users from formatting drives/partitions larger than 32GB in FAT32 format. Mystery solved! That's what the 32 implies. I divided the drive into 2 partitions.
