About creating partition
To create partition is actually to partition hard drive. Only
after you creating partition(s) on a disk, can you make use of
the disk to save all kinds of data. All physical parameter of a
disk are set when you create partition(s) on it, including MBR
(Main Boot Record) and the destination for storing boot
record backup. For other information later needed for the
management of file system and other operating systems, it
will be achieved by later advanced format.
What are the advantages of creating partitions? Generally
speaking, creating more than one partition enables you to
have operating system separate from data, deploy multi-boot
setups, and keep frequently used programs and data near
each other. Therefore, you can manage your computer with
ease. If there is only one partition (namely C drive) on disk:
When recovering the system, the whole c disk (the system
disk) will be formatted. If all data are saved in c disk, they
will all be wiped and cannot be restored.
Too many other things in system disk will slow down system
running.
If there are several partitions and each partition stores
different kinds of data, it is convenient for user to manage
them.
After partition creation, the size of cluster will decrease,
which improve the efficiency of data storage. (Cluster is the
distributive minimum disk space to save files. According to
the stipulation of operating system, a cluster can only be
used to store one file. Therefore, the space occupied by files
can only be integer times of the size of a cluster. However, if
the size of a file is smaller than that of a cluster, the extra
space in the cluster will be wasted. Thus, generally speaking,
a small cluster is better)
Consider all the reasons above, it is necessary to create
more than one partition on a hard disk.
Before you do
For MBR disk, please check how many partitions there are
already on hard drive? Because MBR disk only supports
creating up to 4 primary partitions or 3 primary partitions and
1 extended partition which may include one or more logical
drives. If the number of partitions reaches the upper limit,
please visit how to convert to logical partition to change one
primary partition to logical one and then you can create
partition(s) on it. For GPT disk, you can create partitions
without limitation. And you can have more primary partitions.
However, the Windows implementation restricts this to 128
partitions.
Chapter 5 - File attributes and NTFS permissions We’ve already mentioned both file attributes and NTFS permissions throughout this book. In this chapter we’ll take a closer look at file attributes, and discuss how to view and change attributes from the command line. We’ll also examine NTFS permissions, which are considerably more powerful than file attributes, and discuss how to view and alter them as well. WHAT ARE FILE ATTRIBUTES? “File attributes” are basically pieces of metadata that contain additional information about the file. In Windows, files generally have their names, their types (defined by the file’s extension), and their timestamps. (Certain kinds of files, such as MP3 music files, have additional kinds of metadata, such as the album and artist name.) With file attributes, however, there are four additional pieces of information that you can add to a file. These four pieces of information are: -Archive,...
