Translations:Partitioning Overview and Existing Partition Tables/5/en

There are two types of partition that may be used to divide a hard disk. These are Primary Partitions and Logical Partitions. Primary partitions are a throwback to the early days of computing, and only allow for a hard disk to be divided into a maximum of four parts, for example, you can have a maximum of four primary partitions, or three primaries and one extended partition which may contain several Logical partitions depending upon the architecture. They are, in essence, a way of further sub-dividing one primary partition into logical partitions is known as an Logical partitions. For example:

• sda1 = 1st Primary
• sda2 = 2nd Primary
• sda3 = 3rd Primary
• sda4 = 4th Extended Primary Partition (not actually usable as such)
  • sda5 = 5th Logical
  • sda6 = 6th Logical
  • sda7 = 7th Logical
  • sda8 = 8th Logical
  • and so on, depending upon your disk space and needs.
