H
Hard disk
A fixed storage media along with integrated electronics that consists of several magnetic platters that
rotate synchronously on one spindle.
Hard disks have a relatively high capacity and high read/write speed.
A hard disk is also called a hard disk drive.
Hidden volume
A volume (p. 82) that is made invisible to an operating system.
Hiding a volume is usually done by changing its partition type (p. 78).
I
Initialization
The process of registering a disk in the operating system.
Initialization involves assigning a partitioning scheme (p. 79) (MBR or GPT) and a type (basic or
dynamic) to the disk.
Initialization is usually performed when you add a new hard disk drive to the machine.
L
Logical drive
See Logical volume (p. 77).
Logical volume
A volume which is located on a basic MBR disk (p. 78) and is not a primary volume (p. 79).
Logical volumes usually store user data and sometimes the files that are used by the installed
operating systems.
Unlike the number of primary volumes, the number of logical volumes on the disk is unlimited.
A logical volume is also called a logical drive.
M
Machine
A physical or virtual computer uniquely identified by an operating system installation.
Main volume
Of two volumes being merged, the volume on which the other volume’s files and folders will be
placed.
