简短的回答(Short answer)？是的。等等……但是(Wait…but)为什么呢？你只是把它像一颗坏牙一样拔了很多次，从来没有出过问题。你为什么要现在开始关心？可能发生的最坏情况是什么？
有很多不好的事情可能发生，这只是时间问题。让我们看看如果你继续把它拿出来，你会得到什么，以及为什么会发生这些坏事。
USB驱动器(Do USB Drives Get)如何因不弹出(Ejecting)而被移除而损坏？
USB 驱动器(USB drive)和计算机如何交互(computer interact)非常复杂。首先(First)，电脑必须给U盘(USB drive)供电
，才能正常工作。然后计算机和USB 驱动器(USB drive)将相互通信以建立连接。这需要计算机安装正确的驱动程序。
今天的USB驱动器(USB drive)都是即插即用的，意味着它们可以为计算机提供必要的驱动程序。然后计算机必须了解USB 驱动器(USB drive)上的数据，以便您可以访问它。计算机通过读取USB上的(USB)主引导记录(Master Boot Record)( MBR ) 或分区引导记录 ( PBR ) 或目录结构来执行此操作。
所有这些都发生在您开始使用USB 闪存(USB flash)驱动器之前的几秒钟内。
在您使用闪存驱动器(flash drive)期间，您可能会认为它只是在读取文件，或者每次更改某些内容时都会立即将其写入驱动器。这不是它的工作原理。
读取文件时，仍然会发生变化。系统正在更改文件的元数据，例如更新上次访问或上次修改的日期和时间(date and time)。
更改分批发生。您对某些内容进行更改，更改首先发生在您计算机上的缓存中，然后最终写入USB 驱动器(USB drive)。
此外，其他程序可能正在访问您的USB 驱动器(USB drive)，而您没有意识到这一点。如果您有防病毒或反恶意软件，它可能会随时检查您的驱动器。
因此，在任何时候，即使您没有对闪存驱动器进行任何操作，您的 PC 也可能正在使用它。如果在发生上述任何情况时拔出USB 驱动器(USB drive)，可能会损坏文件或USB 驱动器(USB drive)
本身。
但是等等，还有更多。当您弹出USB 驱动器(USB drive)时，就会发生整个仪式。
就像电脑和光驱有上面的介绍阶段一样，他们也有一个再见阶段(goodbye phase)，他们最后一次握手，说完，然后电脑从USB断开，并停止为其供电。
如果这不能正常发生，就会发生腐败。显然，计算机和 USB(computer and USB) 需要(need closure)在关系结束时关闭。电源部分也很重要。曾经(Ever)从墙上拔下东西，只看到一点点电吗？拔出
闪存驱动器(flash drive)时可能会发生类似的事情，这可能会烧毁您的驱动器。它几乎从未发生过，但它仍然会发生。
可能发生(Could Happen)的最坏(Worst)情况是什么？
最坏的情况(worst-case scenario)是您的USB 驱动器(USB drive)完全停止运行。你不能写它，你不能读它，它就是行不通。
如果它是你不关心(t care)的东西，或者如果你把它全部备份在其他地方，这没什么大不了的。但老实说，这永远不会发生。当它有重要文件或您急于用USB 驱动器(USB drive)上的内容进行演示时，就会发生这种情况。它永远不会在方便的时候发生。
幸运的是，可以修复您的USB 闪存(USB flash)驱动器及其上的数据。除非你拔出来的时候被电损坏了。这可能会发生。
为什么这种情况不会一直发生(Happen)？(Time)
Windows有一项称为“快速删除(Quick Removal)”的功能，通常可以防止发生损坏。快速移除策略(Quick Removal policy)可确保
Windows将USB 驱动器(USB drive)保持在随时可以移除的状态。默认情况下，Windows使用USB 驱动器(USB drive)上的快速删除策略(Quick Removal policy)。
但这并不是万无一失的。在另一个程序写入或访问闪存驱动器时，您仍然可以移除它。
为什么它不会一直发生是因为计算机的速度非常快。在您将文件保存到USB 驱动器(USB drive)然后拔出驱动器时，您的计算机已经写入了文件，开车到咖啡店，喝了杯拿铁咖啡然后回来了。还有一个运气指标。
我怎么知道我正在使用快速移除(Using Quick Removal)？
单击开始按钮(start button)附近的Type here to search栏。开始(Start)输入设备管理器(device manager)。
您将看到设备管理器(Device Manager)作为搜索结果之一。单击(Click)以打开它。
在设备管理器中，展开磁盘驱动器(Disk Drives)并找到您的USB 闪存(USB flash)驱动器。在此示例中，它是Kingston Data Traveler 3.0 USB 设备(USB Device)。在你的情况下可能会有所不同。
右键单击您的 USB 闪存驱动器，然后单击属性(Properties)。
在设备的属性窗口中，单击策略(Policies)选项卡。在那里，您将看到您的USB 驱动器(USB drive)是否设置为使用Quick Removal或 Better Performance。如果它未设置为Quick Removal并且您需要，请选择它并单击OK。
我应该如何弹出 USB 驱动器？
在Windows中，有两种弹出USB 驱动器(USB drive)的好方法，因此它会通过必要的步骤来确保它安全弹出。您可以通过任务栏或文件资源管理器(File Explorer)弹出
USB 驱动(USB drive)器。让我们来看看如何做到这一点。
从任务栏弹出 USB 驱动器
单击(Click)任务栏中的USB 图标(USB icon)。如果您没有看到它，请单击向上箭头以显示任务栏中的所有项目。
上面会出现一个小窗口，列出通过USB插入的所有设备。找到您要弹出的设备并单击它。
Windows安全卸载USB 闪存(USB flash)驱动器后，您将看到以下确认屏幕(confirmation screen)打开。您现在可以安全地移除驱动器。
在Windows 文件资源管理(Windows File Explorer)器中弹出USB 驱动器(USB Drive)
在文件资源管理器(File Explorer)中找到要弹出的USB 闪存(USB flash)驱动器，然后右键单击它。在打开的菜单中，单击Eject。
等待(Wait)几秒钟，您将看到任务栏中的时钟弹出确认通知。(confirmation notification pop)您现在可以安全地移除您的闪存驱动器。
您(Are)现在要弹出USB(Your USB)驱动器吗？
面对现实，即使您现在对弹出USB 闪存(USB flash)驱动器的了解比以往任何时候都多，而且事情会变得多么糟糕，但您可能不会开始弹出驱动器。还是你会？
也许有一天你会从事一项重要的工作项目(work project one)。在拉出USB 驱动器(USB drive)之前，您将暂停。在记住这篇文章以及事情似乎在最糟糕的时候出错的事实后，也许你会弹出那个闪存驱动器。只是(Just)为了安全。
Do You Really Need to Eject a USB Drive Before Removing?
Short answеr? Yes. Wаit…but why? You’ve just yanked it out like a bаd tooth so many times and nothing has ever gone wrong. Why should you start caring now? What’s the worst that could happen?
There’s plenty of bad that could happen and it’s only a matter of time. Let’s see what’s in store for you if you keep just pulling it out, and why these bad things could happen.
How Do USB Drives Get Damaged by Removing Without Ejecting?
How a USB drive and a computer interact together is
surprisingly complex. First, the computer must provide power to the USB drive
so that it can work. Then the computer and the USB drive will talk to each
other to establish a connection. That requires the computer to have the right
drivers installed.
Today’s USB drives are all plug-and-play meaning that they
can provide the necessary drivers for the computer. Then the computer must
understand what data is on the USB drive so it can allow you to access it. The
computer does this by reading the Master Boot Record (MBR) or Partition Boot
Record (PBR) or directory structure on the USB.
All of that happens in the couple seconds before you start
using your USB flash drive.
During the time that you’re using the flash drive, you may
think that it’s just reading files or every time you change something it is
immediately written to the drive. That’s not how it works.
When reading files, there is still changes happening. The
file’s metadata is getting changed by the system doing things like updating the
last accessed or last modified date and time.
The changes happen in batches. You make a change to
something, the change first takes place in a cache on your computer, then it eventually
gets written to the USB drive.
Also, other programs may be accessing your USB drive and you
don’t realize it. If you’ve got antivirus or anti-malware software, it could be
checking your drive at any point in time.
So, at any time, even if you’re not doing anything with the flash
drive, your PC might be using it. If you pull your USB drive out while any of
these things are happening, you can corrupt your files, or the USB drive
itself.
But wait, there’s more. There’s the whole ceremony that
happens when you eject the USB drive.
Just as the computer and the drive have an introduction
phase like above, they also have a goodbye phase where they shake hands one
last time, finish talking, and then the computer disconnects from the USB, and
stops providing power to it.
If that does not happen properly, corruption can happen. Apparently,
the computer and USB need closure at the end of their relationship. The power
supply part is important too. Ever unplug something from the wall and saw just
a little flash of electricity? A similar thing can happen when pulling out the
flash drive and this can cook your drive. It almost never happens, but it still
happens.
What is the Worst that Could Happen?
The worst-case scenario is that your USB drive stops
functioning completely. You cannot write to it, you cannot read from it, it
just does not work.
Not a big deal if it’s stuff you don’t care about or if you
have it all backed up somewhere else. But let’s be honest, that’s never when it
happens. It happens when it has important documents or you’re in a rush to give
a presentation with what’s on the USB drive. It never happens at a convenient
time.
Fortunately, it might be possible to fix your USB flash drive and the data on it. Unless it was damaged by electricity when you pulled it out. That can happen.
Why Doesn’t This Happen All the Time?
Windows has a feature called Quick Removal that usually will
prevent corruption from happening. The Quick Removal policy ensures that
Windows keeps the USB drive in a state where it is ready to be removed at any
time. By default, Windows uses the Quick Removal policy on your USB drives.
It’s not foolproof though. It’s still possible that you
could remove the flash drive while it’s being written to or accessed by another
program.
Why it doesn’t happen all the time is that computers are blazingly
fast. In the time that you saved a file to your USB drive and then pulled the
drive out, your computer has already written the file, drove to the coffee
shop, had a latte and came back. There’s also a measure of luck.
How Do I Know I’m Using Quick Removal?
Click in the Type here to search bar near your start button. Start typing device manager.
You’ll see the Device Manager as one
of the search results. Click to open that.
In Device Manager, expand Disk Drives and find your USB flash drive. In this example, it’s a Kingston Data Traveler 3.0 USB Device. It could be something different in your case.
Right-click on your USB flash drive and
click on Properties.
In the device’s properties window, click on the Policies tab. There you will see if your USB drive is set to use Quick Removal or Better Performance. If it isn’t set to Quick Removal and you want that, select it and click OK.
How Should I Eject the USB Drive?
In Windows, there’s 2 good ways to eject the USB drive so it
goes through the necessary steps to ensure it ejects safely. You can eject a
USB drive through the taskbar or in File Explorer. Let’s go over how to do
that.
Eject USB Drive from Taskbar
Click on the USB icon in the taskbar. If you don’t see it, click on the up arrow to show all items in the taskbar.
A small window will appear above this, listing all the devices plugged in via USB. Find the device you want to eject and click on it.
Once Windows has safely dismounted the USB flash drive, you’ll see the following confirmation screen open. You may safely remove your drive now.
Eject USB Drive in Windows File Explorer
Find the USB flash drive you want to eject in File Explorer and right click on it. In the menu that opens, click on Eject.
Wait for a couple seconds and you’ll see the confirmation notification pop up by the clock in your taskbar. You can now safely remove your flash drive.
Are You Going to Eject Your USB Drives Now?
Face it, even though you now know more about ejecting USB flash drives than you ever wanted, and how bad things can go, you’re probably not going to start ejecting the drives. Or will you?
Maybe you’ll be working on an important work project one day. Before you yank the USB drive out, you’ll pause. Upon remembering this article and the fact that things seem to go wrong at the worst times, maybe you’ll eject that flash drive. Just to be safe.
