partition, and then within that extended partition, we have logical partitions where we can create additional volumes. This is designed to get us around the four-partition limit. Notice that we still have free unallocated spacewithin the extended partition, and we can create more volumes within that space. For example, we could create yet another six-gigabyte volume within the extended partition. We'll give this one the volume label research. So now we have a research volume as well created within our extended partition, so now we actually have five volumes. One, two, three, four, five on Disk 1 that uses MBR partitioning and is a basic disk. Using extended partitions allows us to get around that four-partition limit. Notice there's still additional free space over here we could use if we wanted to to create yet another volume on Disk 1, and I could keep on creating volumes as long as I still have free space available within the extended partition, so those are the rules that you have to live with if you're working with a basic disk. Now, these two disks have already been defined as basic disks, but you're not stuck with that. Differences between Basic Disks and Dynamic Disks 7:38-10:16 You can convert an existing basic disk to a dynamic disk. All you have to do is right click on it, such as here for Disk 2, and then click on "Convert to dynamic disk." We are prompted to specify which diskswe want to convert to dynamic disks. Notice that I could convert Disk 0 and Disk 1 to dynamic disk too, but for our purposes today, let's go ahead and just convert Disk 2. Click OK, and now Disk 2 is not a basic disk anymore but is a dynamic disk. Now, on dynamic disks, you can create volumes the same way that you create them on a basic disk. Right click, we can create, for example, a new simple volume, and let's make this volume about 10 gigs in size. Drive letter J, and we'll give it a volume label of development and create the new volume, and drive J, our development volume, has been createdon our dynamic Disk 2. Now, if you already have a basic disk defined with volumes on it, you can convert it to a dynamic disk as well. Let's go ahead and do that. This time we're going to convert Disk 1, K, "convert," and it gives us a warning that if we convert this disk to a dynamic disk from a basic disk, you won't be able to start any operating systems from any volume on the disk except for the boot volume up here, which really doesn't apply to Disk 1 because we don't have any operating systems installed in any of these volumes, so we're OK, we'll go ahead and click "Yes," go ahead and continue. Now, notice that something significant happened when I did that. The extended partition went away.That's because with dynamic disks, you can have more than four partitions on a given disk, so we don't need the concept of primary and extended and logical volumes anymore. Everything's just a plain old volume, as you can see here. Disk 1 now has one, two, three, four, five volumes on it. Disk 2 has one. So to this point, we have created simple volumes on all of the disks in this system. We have other options that are available to us. Before we do that, though, I need to clear up some space on Disk 1, so I'm actually going to come up here and click "Delete volume" to remove volumes from thisdisk. Let's delete this one as

    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.
