(1) Use extended partition if you want to have more than four volumes on your basic disk.

(2) An extended partition is a portion of a basic disk that can contain logical drives.

(3) An extended partition a portion of a basic disk that can contain logical drives.

(4) Create a primary or extended partition, or logical drive on this basic disk.

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

(6) A logical drive is a volume you create within an extended partition on a basic disk.

(7) In the fstab file listed above, the root file system is on the first IDE hard drive in the fifth partition, the first logical drive in an extended partition.

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

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

(10) If you want to take space from a logical partition to give it to a primary partition or vice versa, you must explicitly resize the extended partition that surrounds the logical partitions.
