One way to have a separate drive is to create a partition. For that, you would need a partition creating program. But there is another way to create a separate hard drive. You can create a virtual hard drive in Windows 7. This is one of the new features added to Windows 7. The Virtual Hard Disk (VHD) format is an image format specification that creates a virtual hard disk incorporated in a single file. It is capable of hosting different native file systems and also providing support for standard disk and file operations.
Here are the steps necessary to create that virtual hard disk.
