how to create a new partition of hard disk?
If you are using windows 7 (maybe Vista, not sure), just run 'Disk Management'. Using that tool, already installed on every Windows 7-machine (you can also acces it using 'Computer Management' if I'm not mistaking), you can very easily monitor your partitions, create and delete new partitions etc. You can also create spanned and striped volumes, as well as configure RAID0 discs. Plenty of options for your purposes I think :)
Kind regards,
