管理卷和分区

是一个描述硬盘等存储设备的术语。当您把存储设备分成若干个区之后,它也可以指设备上的部分存储空间。您可以将卷挂载到计算机上。您可以挂载硬盘、USB 驱动器、DVD-RW、SD 卡以及其他媒体。如果某个卷现在处于已挂载状态,您就可以对其进行读取和写入操作。

已被挂载的卷一般被称为分区,尽管这两个术语严格来说并不相同。“分区”是指一个磁盘驱动器上的物理存储区域。分区安装后,也可以被称为卷,因为您可以对其进行读写操作。

使用磁盘实用工具查看和管理卷和分区

You can check and modify your computer’s storage volumes with the disk utility.

  1. Open the Desktop and start Disks.

  2. In the list of storage devices on the left, you will find hard disks, CD/DVD drives, and other physical devices. Click the device you want to inspect.

  3. The right pane provides a visual breakdown of the volumes and partitions present on the selected device. It also contains a variety of tools used to manage these volumes.

    请注意:使用这些实用程序可能会彻底清除您磁盘上的数据。

一般来说,您的计算机有至少一个分区和一个单一的交换分区。交换分区由操作系统用来进行内存管理,很少被挂载。主分区包含您的操作系统、应用程序、设置以及个人文件。为安全或方便起见,这些文件还可能分布在多个分区。

One primary partition must contain information that your computer uses to start up, or boot. For this reason it is sometimes called a boot partition, or boot volume. To determine if a volume is bootable, select the partition and click the menu button in the toolbar underneath the partition list. Then, click Edit Partition… and look at its Flags. External media such as USB drives and CDs may also contain a bootable volume.
