Partitioning for 300GB

My new Seagate Barracuda 300GB hard drive just arrived. I’ll need some time to redo my entire computer (currently there are 4 operating systems). Whenever I purchase a new harddrive (about once ever 2 years) I always put some serious evaluation into how I will partition it. Some points I consider Windows is primary operating system A second Windows should be possible Windows should have at least seperate ‘applications’ and ‘work’ partitions Multiple Linux distributions should be possible (2-3) Swap partition can be shared in Linux At least /home partition should be shared in Linux In truth I only have about 3-4 GB of actual work and about 6-8 GB of media to save.
