The Advantages of Partitioning a Disk

What are the advantages of partitioning a disk, rather than using the entire disk as one partition?

When partitioning, you are dividing physical devices, such as disks, into independent sections; physically or logically.  This provides you with several advantages.  For one, each partition can have its own file system and directory structure.  This provides the option of providing separate operating system facilities on each partition.  This allows each partition to have its own bootstrap loader, operating system, and file management system.

A user may have certain files that require a separate operating system, or also perform better when separate from other files.  I have seen this work with a positive affect where a partition can be created to keep system critical software and files in a partition separate from the user’s programs.  If a virus or corrupt file is found, let’s say from a corrupt MS Word or Windows Media video file, it will already be separated from the system files required to boot and run the computer.

Partitions provide added security to important files, and also add to the organization you can utilize on a computer, much to the effect of using a tiered file cabinet over the chaos of just scattering papers on your desk.
