It doesn't matter which disk it's on, and it doesn't have to be the first one, it just has to be on a primary partition. Extended Partition 3:40-5:04 Now, I just said that you can only have four partitions per disk, well, there is a little exception to that rule. And that exception is a special type of partition called an extended partition, and it allows you to break the four partition rule. An extended partition is not required, so you don't have to use it if you don't want to, but if you need to have more than four partitions on a particular hard disk drive, then an extended partition comes in handy. However there are some limitations to an extended partition. An extended partition is not bootable, so, your operating system files cannot reside in an extended partition. Your bootloader won't be able to boot the system if you put your system files within an extended partition. Also, you can only have one extended partition per storage device. Now we can have up to four primaries, but if we choose to use an extended partition, we can only have one extended partition. So, that means we can have up to three primary partitions and one extended partition on a hard disk drive. We can also have just one primary partition, and one extended partition, or, if we had two hard disks installed in the computer system, we could have two extended partitions, one on each hard disk. Also, you cannot create an extended partition on a hard disk drive that already has four primary partitions. Extended partitions cannot be directly formatted. Instead, we create logical partitions within the extended partition. Logical Partition 5:05-7:14 These logical partitions reside within one extended partition. We can create up to 24 logical partitions, within one extended partition. This is how you break the four partitions per hard disk rule.You're still limited to four partitions when you're dealing with primary and extended, but once you start creating logical partitions within a single extended partition, you can have up to 24 separate logical partitions within one single extended partition. After you create your logical partitions within the extended partition, you can format each logical partition just as if it were a primary partition with the file system. After the partitions are formatted,the operating system doesn't know the difference between a logical partition within an extended partition, and a standard primary partition. For example, let's suppose that I have a single hard disk drive on my system. I create one partition on this drive that encompasses about half of the drive. And I create it as a primary partition. Then, I create a file system on it, and I install my operating system here. This is my C: drive. In addition, let's suppose I create an extended partition encompassing the second half of the drive, and within that extended partition, I create three logical partitions. By doing this, I have essentially four different partitions in my system, even though I really only have two real partitions, a primary and an extended. But, because I've created logical partitions within the extended, I've created four partitionson a single hard disk drive.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
