Chapter 5.7 Storage Management
The disk must have contiguous free space on the same disk.
The system volume can only be extended using contiguous free space on the same disk. This is the same for both basic and dynamic disks. Any volume can only be extended if it is unformatted or formatted with NTFS.
The system volume can be on either a basic or dynamic disk. The system volume cannot be extended or spanned to non-contiguous space or to space on another disk.
To use multiple disks in the single logical storage unit, upgrade all disks to dynamic disks. Create a spanned volume. A simple volume contains storage space from a single disk. Use basic disks to create primary and extended partitions. Partitions cannot include storage space from multiple disks.
An extended partition is subdivided into logical drives. You cannot format an extended partition, you can only format the logical drives within the partition. You can have only a single extended partition per disk. The extended partition cannot be set as active, and therefore cannot be used to boot the computer. Use a primary partition to set the partition as active, boot the computer or to create multiple partitions per disk.
Windows supports basic and dynamic disks. When you install Windows, your hard disks are automatically initialized as basic. You can convert them to dynamic disks after Windows is installed. You can use both basic and dynamic disks on the same computer system, but a volume consisting of multiple disks, such as a mirrored volume, must use only one type of disk. Primary and extended are terms that describe partition types on basic disks.
Within Windows 7, Disk Management is found under storage in Computer Management,
Within Windows 10, Disk Management is found in the list of utilities that appear when you right-click the Start Menu.
Use Disk Management to view, modify, and create partitions. Use Device Manager to update drivers and manage device-specific settings. Use the Services console to start and stop processes that run in the background. Use Explorer to view the contents of a volume, or to format a drive.
Because this is the system volume, the only way to add space to the volume using space on the new disk is to create a mount point. A mount point is an empty folder on the existing volume that points to another partition. Data saved to the folder is physically saved on the referenced partition. To create a mount point:
-Create an empty folder on the existing volume.
-Create a partition on the new disk without a drive letter.
-Mount the partition to the empty folder on the existing volume.
You cannot extend the volume to another disk because the volume is the system volume. You cannot extend the system volume even if it is on a dynamic disk. You can create mount points on basic or dynamic volumes.
A mount point is an empty folder on the existing volume that points to another partition. Data saved to the folder is physically saved on the referenced partition. Extending a volume adds space to the volume. Extending a volume using space on a different disk creates a spanned volume. You cannot extend the system volume using space on a second disk. A striped volume uses two equal portions on two disks. You can create a new striped volume, but you cannot stripe an existing volume.
