使用BitLocker To Go^{(BitLocker To Go)}保护您的外部硬盘驱动器或USB记忆棒上的数据是一个明智之举，可确保您的文件不提供给任何接触到您的驱动器的人。虽然BitLocker To Go加密数据确实需要一段时间，但在初始设置之后，使用加密驱动器应该没有问题。您所要做的就是通过输入您最初设置的BitLocker密码来解锁它。^(BitLocker)以下是该过程的工作原理：

步骤 1. 插入加密的BitLocker驱动器（USB、外置硬盘、笔式驱动器等）

第一步是取出使用BitLocker加密的驱动器，并将其插入您的 PC。它可以是任何东西：USB记忆棒、外部硬盘驱动器、笔式驱动器等。

等待^(Wait)Windows 10^{(Windows 10)}识别您插入的驱动器。当您被要求选择驱动器发生的情况时，不要单击任何内容，并忽略通知。

步骤 2. 解锁加密的BitLocker驱动器（USB、外部硬盘驱动器、笔式驱动器等）

在要求您选择刚插入的驱动器会发生什么的通知之后，您会看到另一个通知，通知您“此驱动器受 BitLocker 保护”。^{("This drive is BitLocker-protected.")}

单击或点击此“解锁驱动器”^{("Unlock drive")}通知以查看输入BitLocker密码的对话框，如下所示。输入^(Enter)密码，如果您希望 Windows 10 在每次将驱动器插入同一台计算机时自动解锁驱动器，请单击或点击“更多选项”。^{("More options.")}

选中“在这台电脑上自动解锁”^{("Automatically unlock on this PC,")}框，然后按解锁^(Unlock)。

提示：^(TIP:)您需要输入使用BitLocker To Go加密驱动器时设置的密码。有关更多详细信息，请阅读：在 Windows 10 中使用 BitLocker To Go 加密 USB 驱动器^{(Encrypt a USB drive with BitLocker To Go in Windows 10)}。

如果您没有看到解锁加密驱动器的通知，请不要担心。您所要做的就是打开文件资源管理器^{(open File Explorer)}。一种快速的方法是按键盘上的Windows + E键。在文件资源管理器^{(File Explorer)}中，转到这台电脑^{(This PC)}，然后双击（或双击）位于“设备和驱动器”下的加密驱动器。^{("Devices and drives.")}BitLocker驱动器的图标上应该有一个锁，如下面的屏幕截图所示。

然后会要求您输入BitLocker密码，如本节前面所示。

您还可以使用控制面板^{(Control Panel)}解锁 BitLocker 驱动器。打开^{(Open )}控制面板^{(Control Panel)}，然后转到“系统和安全”^{("System and Security,")} ，然后转到“BitLockerDrive 加密”。^{("BitLockerDrive Encryption.")}在“可移动数据驱动器 - BitLocker To Go”^{("Removable data drives - BitLocker To Go")}下，单击或点击所需的加密驱动器，然后按旁边的解锁驱动器链接。^{(Unlock drive)}

然后，系统会要求您输入BitLocker密码，如前所示。

提示：^(TIP:)如果您不知道BitLocker密码，您可以仅使用其恢复密钥解锁BitLocker驱动器。^(BitLocker)请参阅：如何从 BitLocker 加密闪存驱动器中拯救您的数据^{(How To Rescue Your Data From a BitLocker Encrypted Flash Drive)}。

步骤 3. 使用解锁的BitLocker驱动器并在完成后将其弹出

输入BitLocker密码后，可以从文件资源管理器中打开^{(File Explorer)}USB驱动器并像使用任何其他驱动器一样使用它。请注意^(Notice)，它的驱动器图标有一个打开的锁定符号，如下所示。

使用完 BitLocker 加密驱动器后，最好使用Windows 中的“安全删除硬件”^{("Safely Remove Hardware")}功能将其弹出。^{( feature)}

提示：^(TIP:)如果您不想再在加密驱动器上使用BitLocker To Go ，请阅读^{(BitLocker To Go)}如何禁用 BitLocker To Go 加密并删除解锁密码^{(How to disable BitLocker To Go encryption and remove the unlock password)}。

How to unlock a BitLocker USB drive or external hard drive

Protеcting the data on your external hard drіve or USB memorу stick with BitLocker To Go is a smart move to ensure that your files are not available to anyone who gets their hands on your drive. While it does take a while for BitLocker To Go to encrypt the data, after the initial setup, you should have no trouble using the encrypted drive. All you have to do is to unlock it by entering the BitLocker password that you have set initially. Here's how the process works:

Step 1. Plug in the encrypted BitLocker drive (USB, external hard drive, pen drive, etc.)

The first step is to take the drive that's encrypted with BitLocker, and plug it into your PC. It can be anything: a USB memory stick, an external hard drive, a pen drive, etc.

Wait for Windows 10 to recognize the drive that you plugged in. When you are asked to select what happens with the drive, don't click on anything, and ignore the notification.

Step 2. Unlock the encrypted BitLocker drive (USB, external hard drive, pen drive, etc.)

After the notification where you are asked to choose what happens with the drive that you just plugged in, you see another one, informing you that "This drive is BitLocker-protected."

Click or tap on this "Unlock drive" notification to see the dialogue for entering the BitLocker password shown below. Enter the password and, if you want Windows 10 to automatically unlock the drive each time you plug it into the same computer, click or tap "More options."

Check the box that says "Automatically unlock on this PC," and then press Unlock.

TIP: You need to enter the password that you set when the drive was encrypted with BitLocker To Go. For more details, read: Encrypt a USB drive with BitLocker To Go in Windows 10.

If you don't see the notification for unlocking the encrypted drive, do not worry. All you have to do is open File Explorer. A quick way is to press the Windows + E keys on your keyboard. In File Explorer, go to This PC, and double-click (or double-tap) on the encrypted drive, found under "Devices and drives." The BitLocker drive should have a lock on its icon, like in the screenshot below.

Then you are asked to enter the BitLocker password, as shown earlier in this section.

You can also use the Control Panel to unlock a BitLocker drive. Open Control Panel, and go to "System and Security," followed by "BitLockerDrive Encryption." Under "Removable data drives - BitLocker To Go" click or tap on the encrypted drive that you want, and then press on the Unlock drive link next to it.

Then, you are asked to enter the BitLocker password, as shown previously.

TIP: If you do not know the BitLocker password, you can unlock the BitLocker drive only using its recovery key. See: How To Rescue Your Data From a BitLocker Encrypted Flash Drive.

Step 3. Use the unlocked BitLocker drive and eject it when done

After you enter the BitLocker password, the USB drive can be opened from File Explorer and used like any other drive. Notice that its drive icon has an open lock symbol, as shown below.

When you are done working with the BitLocker-encrypted drive, it is a good idea to eject it using the "Safely Remove Hardware" feature in Windows.

TIP: If you no longer want to use BitLocker To Go on an encrypted drive, read How to disable BitLocker To Go encryption and remove the unlock password.

Do you use BitLocker To Go to protect the data on your removable flash drives?

People and companies who work with sensitive data should consider using BitLocker to encrypt the USB memory sticks, hard drives, or pen drives that are used to transfer data between computers and devices. BitLocker To Go not only makes it easy to encrypt any USB drive, but also helps you unlock it if you know the encryption password.
