Be aware of the following when managing partitions and volumes: Use Disk Management or DiskPart to create, format, and manage partitions and volumes. You access Disk Management on Windows systems through Computer Management. You access DiskPart from the command prompt by entering cmd . Basic and dynamic disks use the same hardware, but different partitioning methods. You can convert a basic disk to a dynamic disk without losing data in existing partitions. o Existing basic volumes and logical drives in the extended partition are converted to dynamic volumes. o You must reboot the system to complete the conversion if the disk contains the boot or system volume, or if the volume includes the pagefile. o To convert from a dynamic disk to a basic disk, you must delete all existing volumes. The active partition identifies the partition that contains the operating system (or the program that loads the operating system) used to start the computer. o You can have only one active partition at a time. o The extended partition or a logical drive on the extended partition cannot be set to active.

You cannot install the operating system on a dynamic disk. You can, however, upgrade a basic disk containing the operating system to a dynamic disk after installation. When you shrink a partition, unmovable files (e.g., the paging file or the shadow copy storage area) are not automatically relocated and you cannot decrease the allocated space beyond the point where the unmovable files are located. If you need to shrink the partition further, check the Application Log for Event 259, which identifies the unmovable file. Next, move the paging file to another disk, delete the stored shadow copies, shrink the volume, and then move the paging file back to the disk. You can shrink primary partitions and logical drives on raw partitions (those without a file system) or partitions using the NTFS file system. To shrink a partition, you must be a member of Backup Operators or Administrators (or equivalent) to complete this process. GPT Partitioning 0:00-0:51 In this lesson, we're going to talk about GPT partitioning. GPT stands for GUID Partition Table. It's called GUID Partition Table because every partition on the drive has a globally unique identifier, or GUID. That means that each partition worldwide would have its own unique identifying number. GPT is a new standard that's gradually replacing MBR, or Master Boot Record. GPT is associated with UEFI, and since UEFI replaces the legacy BIOS with something more modern, GPT replaces the MBR partitioning system with something more modern. MBR partitioning dates back to the early 1980's. In the late 1990's, Intel developed a new partition table format that became part of UEFI. As of 2010, GPT became a subset of the UEFI specification.

    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.
