当前 Windows 用户对新买电脑的硬盘分区的理由有哪些?分区。你们知道啥叫分区不?知道啥叫分区不?好吧又到了科普时间。
Disk partitioning is the act of dividing a hard disk drive (HDD) into multiple logical storage units referred to as partitions, to treat one physical disk drive as if it were multiple disks, so that different file systems can be used on each partition.[1]换句话说,就是把一块硬盘的所有存储空间割开,规定不同部分之间数据相互隔离,这样在逻辑层上面就能把一块硬盘当 N 块用。(暂且不讨论主分区数量限制和磁盘分区表的问题)
In the context of computer operating systems, a volume or logical drive is a single accessible storage area with a single file system, typically (though not necessarily) resident on a single partition of a hard disk. Although a volume might be different from a physical disk drive, it can still be accessed with an operating system's logical interface. However, a volume differs from a partition. [2]卷是一个比分区更高级(High-level)的概念,是应用层和用户最终能接触到的存储器表现形式。普通用户在日常操作中所遇到的“分区”,其实就是这里所说的卷。而且,卷不一定要建立在分区的基础之上:大多数软盘是没有分区这个概念的,但是操作系统仍然会把整张软盘当成一个卷来挂载。
这个例子描述了一台具有两块硬盘、搭载 Windows XP 操作系统的计算机。第一块硬盘具有两个分区,第二块硬盘只有一个分区。操作系统安装在第一块硬盘的第一个分区上。
在这个例子中:
- “C:”、“D:” 和 “E:” 为卷(Volume);
- “硬盘 1”和“硬盘 2 ”为物理硬盘(Hard Disk);
- “分区 1”和“分区 2”为分区(Partition);
- 表格中的任意一项(文件系统除外)均可被称为一个驱动器(Drive)。[3]
