You're not doing anything with partitions that you can't do easier, cheaper, and more flexibly with multiple directories (folders) on one partition. So go ahead and use one big partition on the disk. Or one big one and one small 5GB one for experimenting with Linux and/or future OS releases. Partitions were useful when disks were much smaller, and we needed to separate out the fixed size stuff from the variable sized stuff. Nowadays there is much less justification for using multiple partitions. The right disk technology is one or two partitions, journalled filesystems, and RAID protection. Anything else is just organization for its own sake. Peter
