Cluster. Information storage unit in such file systems as FAT and NTFS. Every
file occupies a certain number of whole clusters, so the more the cluster size
the higher the losses are that are due to file size adjustment, but the smaller
the cluster the more place do the cluster distribution tables occupy.
Configuration file. Configuration. Most operating systems have configuration
files. Usually these are files that keep different options and parameters of the
operating system itself and of applications installed. Acronis OS Selector
allows creating multiple configurations of one operating system by backing
up configuration files for each configuration.
Configuration list is the main part of Acronis OS Selector Boot Menu.
Configuration list can be adjusted very flexibly and aside from configurations
contains also Boot From Floppy sections, separators and comments.
Cylinder. A group of all the tracks on all the magnetic platters of a hard disk
that can be accessed without moving the magnetic head. Access to the data
inside one cylinder is much faster than moving the head from one cylinder to
the other.
Deactivation of Acronis OS Selector. You can deactivate Acronis OS Selector
when booting from an installation media or directly from Setup. In this case
you are prompted to choose an operating system configuration. After
deactivation the selected configuration will be booted directly, bypassing
Acronis OS Selector. Boot from the installation media to re-activate Acronis
OS SelectorOS Selector.
Detection (adding, scanning) of operating systems. Every time Acronis OS
Selector is executed it checks if any changes were made to the hard disk
partition structure of the computer and upon finding any it scans for
operating systems. Newly found operating systems are registered by Acronis
OS Selector and their configurations are automatically added to Boot Menu
configuration list. This is called detection of operating systems (see 5.1
«Automatic Setup Operation Mode»). Manual detection and addition of an
operating system can be performed should Acronis OS Selector fail to detect
that a new operating system was installed (see 5.8 «OS Detection Wizard»).
Disc. A non-magnetic storage media (compact disc, CD-RW, or DVD).
Disk. A magnetic storage media (floppy disk or hard disk).
Disk Administrator is a program from Acronis OS Selector package that allows
performing various operations with hard disk partitions including on-the-fly
resizing without data loss.
Diskette. Floppy disk. A removable storage media that consists of a flexible
magnetic platter enclosed in a protective envelope. The most common are
3.5-inches diskettes with 1.44 megabyte capacity.
