What is partitioning a hard disk means?

Partitioning a hard disk is to divide a hard disk into different logical disks so that each partition acts as a separate disk. You can have three primary partition and one extended partition. The extended partition can be divided into 24 logical partitions.

Why should you partition a hard disk ?

Suppose if you have all backed up files and folders in the same drive i.e C: and if your C: drive suddenly crashes then you may not be able to retrieve the files. But if you have divided the hard disk into different partitions then you can store them safely into other partitions so that if the C: drive containing the operating system crashes then you can still retrieve them.

You can use another partition to create a system image file so that in case if your operating system crashes then you can restore your operation system from the system image stored in the other partition.

If you want to have dual operating system in your computer i.e win7 and win vista then you can create it easily if you have more partitions.
