volumes off of these disks, they automatically converted back to basic disks. So if I wanted to, say, create a span volume on these disks now, I would first have to convert them to dynamic disks. MBR and GPT Partitioning 13:10-14:29 Now there's one other thing we need to talk about before we end this demo, and that is the difference between MBR and GPT disks. Now, MBR has been around for a very long time. It's got a lot of limitations that we already talked about. Using a dynamic disk is one way to get around those limitations. Another option for getting around the MBR limitations is to use a GPT disk instead. With a GPT partitioning scheme, all the limitations we associate with MBR are gone. There are no such thing as primary and extended and logical partitions in GPT. All the partitions are just partitions, and I believe Windows will support like up to 128 GPT partitions per disk. GPT also supports very large disks and partitions, so in order to use GPT, we need to right click on this disk and select "Initialize disk," and then with Disk 3 selected, we need to decide whether we're going to use MBR or GPT partitioning. Let's go ahead and use GPT for this disk, and now that I've done that I can come down here and create volumes just like I did with the MBR disk. All right, the new simple volume we've created on our GPT disk has now been created and we can save data on it just as we would a traditional partition volume over here on an MBR type disk. Summary 14:30-14:50 That's it for this demonstration. In this demo, we talked about how to manage disks, partitions, and volumes in Windows using Disk Management. We talked about how to create simple volumes. We talked about how to create span volumes. We talked about the differences between basic disks and dynamic disks, and we also discussed the difference between disks that use MBR partitioning formatand disks that use the GPT partitioning format. Creating Volumes with Diskpart 0:00-1:54 In this demonstration, we're going to practice managing disk partitions and volumes using the diskpart command. Now, normally when you need to, say create a new volume on a hard disk in a desktop system you'd come over here. Right-click, and use the disk management utility. That's great but understand that there will be some Windows systems that you will encounter that may not have a graphical user interface implemented. For example, a Windows Server system may not have a graphical user interface. If that's the case, then you have to know how to do this from the command prompt and this is done using the diskpart command. So, let's go over here, right-click on the Windows icon and then select command prompt adminbecause we will need administrator level permissions to complete these tasks and I'm going to make this window bigger so we can see what we're doing. So, in this computer system I have four hard disks implemented. The first hard disk has my Windows operating system. The second and third hard disks are blank. They don't have anything on them. And then the fourth disk already has a volume defined on it. So, what we want to do is create volumes on the second and third

    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.
