extended partition

When more than four partitions are required, as is often the case, one of the primary partitions must instead become an extended partition.

Because an extended partition is also a primary partition it might be necessary to remove a primary partition first.

So if you want more than four partitions on an IDE drive, you will lose one partition number to the extended partition.

Note that the extended partition is locked in this way if any of its contained logical partitions are in use, including swap space.

Beginning with the fourth volume, each volume will be configured as a logical drive within an extended partition.

You cannot store data in an extended partition without first creating a logical partition within it.

Swap space is located in the first IDE hard drive in the sixth partition, the second logical drive in an extended partition.

An extended partition is a way to get around a limit on the number of primary partitions a basic disk can have.

If you need more than four partitions, give away one primary partition to create an extended partition.

Data is stored in the logical partitions within the extended partition.

All your logical partitions must reside within a single extended partition, and so must be contiguous.

That's because you can't directly boot from anywhere inside an extended partition.

That's where the extended partition comes into play.

If you want more partitions you should first create an extended partition.

An extended partition is simply a container for one, or usually more, logical partitions.

An extended partition is a container that can hold one or more logical drives.
