. multiple consecutive logical partitions can be used as an extended partition. One hard disk can only have one extended partition.Summary: In other words, there are still up to four primary partitions and extended partitions on a physical hard disk. However, extended partitions can be further divided into logical partitions. for most users, there is no difference in the use of primary and logical partitions. In this way, a fast hard disk can have almost unlimited partitions. Partition instance
