安卓格式化和擦除分区_如何在Mac上擦除和格式化USB驱动器

安卓格式化和擦除分区

Macs support a variety of file systems. By default, they format disks with the Mac-only OS X Extended file system. But, if you plan on using an external drive with both Macs and PCs, you should format the disk with the exFAT file system instead.

Mac支持各种文件系统。 默认情况下，它们使用仅Mac OS X扩展文件系统格式化磁盘。 但是，如果计划在Mac和PC上同时使用外部驱动器，则应使用exFAT文件系统格式化磁盘。

如何检查驱动器的文件系统 (How to Check a Drive’s File System)

So how do you know if your USB drive is using the right format? You don’t need to do anything special with Disk Utility–just plug in your USB drive and open the Finder. Right-click or Control-click the drive’s icon in the Finder’s sidebar (or on your desktop) and select “Get Info.”

那么，如何知道您的USB驱动器使用的格式正确 ？ 您无需对“磁盘工具”进行任何特殊处理，只需插入USB驱动器并打开Finder。 右键单击或按住Control键单击Finder侧边栏中(或桌面上)的驱动器图标，然后选择“获取信息”。

You’ll see the drive’s file system displayed to the right of “Format” under the General heading. In the screenshot below, the drive is formatted with the exFAT file system.

您将在常规标题下看到驱动器的文件系统显示在“格式”的右侧。 在下面的屏幕快照中，驱动器已使用exFAT文件系统格式化。

如何在Mac上格式化驱动器 (How to Format a Drive on a Mac)

If you want to use a different file system on your USB drive, you’ll need to “format” it. Again, formatting a drive will erase it completely, so make sure you have everything backed up that you want to keep.

如果要在USB驱动器上使用其他文件系统，则需要对其进行“格式化”。 同样，格式化驱动器会完全擦除它，因此请确保已备份所有要保留的内容。

To format a drive on a Mac, you’ll need the built-in Disk Utility application. Press Command+Space to open the Spotlight search dialog, type “Disk Utility”, and press “Enter” to launch the app.

要在Mac上格式化驱动器，您需要内置的Disk Utility应用程序。 按Command + Space打开Spotlight搜索对话框，键入“磁盘工具”，然后按“ Enter”启动应用程序。

You can also open a Finder window, select “Applications” in the sidebar, and head to Utilities > Disk Utility.

您也可以打开Finder窗口，在边栏中选择“应用程序”，然后转到“实用程序”>“磁盘实用程序”。

Your connected drives will appear under “External” in the Disk Utility’s sidebar. Select the drive by clicking its name.

您连接的驱动器将出现在“磁盘工具”侧边栏中的“外部”下。 单击驱动器名称，选择驱动器。

Click the “Erase” button after selecting the entire drive to erase the entire drive and create a single partition on it.

选择整个驱动器后，单击“擦除”按钮以擦除整个驱动器并在其上创建一个分区。

You’ll be asked to provide a name for the disk, which will appear and identify the disk when you connect it to a Mac, PC, or another device.

系统会要求您提供磁盘名称，当您将其连接到Mac，PC或其他设备时，该名称将显示并标识该磁盘。

You’ll need to choose between several file systems:

您需要在多个文件系统之间进行选择：

• OS X Extended (Journaled): This is the default, but it’s only natively supported on Macs. It’s also known as HFS+. This file system is necessary if you plan on using the drive for Time Machine backups–otherwise, you’ll want to use exFAT for maximum compatibility.

  OS X扩展(日志) ：这是默认设置，但Mac本身仅支持它。 也称为HFS +。 如果计划将驱动器用于Time Machine备份，则此文件系统是必需的-否则，您将希望使用exFAT以获得最大的兼容性。

• OS X Extended (Case-sensitive, Journaled): On a case-sensitive file system, “file” is different from “File”. By default, Mac OS X doesn’t use a case-sensitive file system. This option exists because it matches the traditional behavior of UNIX and some people might need it–don’t select this unless you know you need it for some reason.

  OS X扩展(区分大小写，日记) ：在区分大小写的文件系统上，“文件”与“文件”不同。 默认情况下，Mac OS X不使用区分大小写的文件系统。 该选项之所以存在是因为它与UNIX的传统行为相匹配，并且某些人可能需要它-除非您出于某种原因知道需要它，否则请不要选择它。

• OS X Extended (Journaled, Encrypted): This is the same as the standard OS X Extended file system, but with encryption. You’ll have to enter a password, and you’ll need to provide that password whenever you connect your drive to your Mac.

  OS X扩展(日志式，已加密) ：与标准OS X扩展文件系统相同，但具有加密功能。 您必须输入密码，并且每次将驱动器连接到Mac时都需要提供该密码。

• OS X Extended (Case-sensitive, Journaled, Encrypted): This is the same as the standard OS X Extended (Case-senstiive) file system, but with encryption.

  OS X扩展(区分大小写，日记，加密) ：与标准OS X扩展(区分大小写)文件系统相同，但具有加密功能。

• MS-DOS (FAT): This is the most widely compatible file system, but it has some limitations–for example, files can only be 4GB or less in size each. Avoid this file system unless you have a device that requires FAT32.

  MS-DOS(FAT) ：这是最广泛兼容的文件系统，但是它有一些限制-例如，每个文件的大小只能为4GB或更小。 除非您的设备需要FAT32，否则请避免使用此文件系统。

• ExFAT: ExFAT is almost as widely compatible as older FAT file systems, but doesn’t have the limitations. You should use this file system if you may share the drive with Windows PCs and other devices like the PlayStation 4 and Xbox One consoles. ExFAT is the ideal cross-platform file system. It’s not natively supported on many Linux distributions, but you can install exFAT support on Linux.

  ExFAT ： ExFAT与旧的FAT文件系统几乎兼容 ，但没有限制。 如果可以与Windows PC和其他设备(如PlayStation 4和Xbox One控制台)共享驱动器，则应使用此文件系统。 ExFAT是理想的跨平台文件系统。 许多Linux发行版本身都不支持它，但是您可以在Linux上安装exFAT支持 。

For external drives, it almost always makes sense to format in ExFAT, unless you’re using the drive for Time Machine.

对于外部驱动器，除非您将驱动器用于Time Machine，否则在ExFAT中进行格式化几乎总是有意义的。

You’ll also be asked to choose between a partition scheme: GUID Partition Map, Master Boot Record, or Apple Partition Map. GPT is more modern, while MBR is older. Both also work with Windows PCs. APM is an older, Mac-only partition scheme.

您还将被要求在以下分区方案之间进行选择：GUID分区图，主启动记录或Apple分区图。 GPT更现代，而MBR更老 。 两者均适用于Windows PC。 APM是一种较旧的，仅限Mac的分区方案。

This choice doesn’t really matter if you don’t plan on booting from the drive. If in doubt, just select the default GUID Partition Map (GPT) scheme. Avoid the Mac-only Apple Partition Map (APM) scheme.

如果您不打算从驱动器启动，则此选择并不重要。 如有疑问，只需选择默认的GUID分区图(GPT)方案。 避免使用仅限Mac的Apple分区图(APM)方案。

Click the “Erase” button when you’re done and Disk Utility will format your disk with the settings you specified. This will erase all the files on the drive!

完成后，单击“擦除”按钮，“磁盘工具”将使用您指定的设置来格式化磁盘。 这将清除驱动器上的所有文件！

You’re now done–be sure to eject the disk before you remove it from your Mac. You can do this by clicking the eject icon to the right of the disk in the Finder or Disk Utility windows.

现在，您已经完成了–在从Mac删除磁盘之前，请确保弹出磁盘。 您可以通过在Finder或“磁盘工具”窗口中单击磁盘右侧的弹出图标来执行此操作。

You can also right-click or Option-click the drive in Finder or on your desktop and select the “Eject” option.

您也可以在Finder中或在桌面上右键单击或Option单击驱动器，然后选择“弹出”选项。

Macs do have some limited support for other file systems–for example, Macs can read files on Windows-formatted NTFS volumes, but can’t normally write to NTFS drives. Macs don’t have an integrated way to format partitions with NTFS, either. Use exFAT for excellent compatibility with Windows without FAT32’s limitations.

Mac对其他文件系统确实有一些有限的支持-例如，Mac可以读取Windows格式的NTFS卷上的文件，但通常无法写入NTFS驱动器 。 Mac也没有使用NTFS格式化分区的集成方法。 使用exFAT可实现与Windows的出色兼容性，而不受FAT32的限制。
