问题 (The Question)

SuperUser reader misha256 wants to know if unplugging a portable USB hard drive can damage a computer:

SuperUser阅读器misha256想知道拔出便携式USB硬盘驱动器是否会损坏计算机：

I was reading through the manual for a Samsung portable USB hard drive that I have and came across this warning:

我正在阅读我所拥有的三星便携式USB硬盘驱动器的手册，并遇到以下警告：

• Detaching the USB cable while file transfer is in progress can damage your computer and/or Portable Series External Hard Drive.在文件传输过程中卸下USB电缆可能会损坏计算机和/或Portable Series外置硬盘驱动器。

Here is the original warning:

这是原始警告：

Seriously? I am going to fry my computer by doing something that USB was explicitly designed for right from the beginning (hot-plugging)? Surely a computer does not suffer damage just because a data transfer fails.

认真吗 我将通过一开始就专门为USB设计明确的功能(热插拔)来炸计算机。 当然，仅由于数据传输失败，计算机就不会遭受损坏。

Short Answer

简短答案

That claim of damage is more of a legal way for a manufacturer to protect themselves on the off-hand chance that something goes wrong, meaning it is practically nonsense. It is no different than the obtuse language used in an End-User License Agreement (EULA) in the world of software; the manufacturer is right, you are wrong, our company has better lawyers than you, give us your money for a product, have a nice day, and goodbye.

对于制造商而言，提出损害赔偿的权利更是一种合法的方式，可以在出现问题的临时机会上保护自己，这实际上是无稽之谈。 它与软件领域的《最终用户许可协议》(EULA)中使用的钝性语言没有什么不同； 制造商是对的，您错了，我们公司的律师比您强，请给我们您购买产品的钱，祝您有美好的一天，再见。

I highly doubt that anything would be seriously damaged by removing a USB hard drive that is still active. So I would not live my life in fear of a warning like this.

我非常怀疑，卸下仍处于活动状态的USB硬盘驱动器会严重损坏任何东西。 因此，我不会因为担心这样的警告而过自己的生活。

I would however take this nonsense to mean that if something did go wrong, then the manufacturer would avoid any responsibility or liability. Instead, they would claim that the fault is yours since you failed to properly use the device as instructed in that little pamphlet most people immediately throw out when they purchase such a device.

但是，我认为这是胡说八道，如果出现问题，制造商将避免承担任何责任。 取而代之的是，他们会认为这是您的错，因为您没有按照该小册子中的说明正确使用该设备，大多数人在购买此类设备时会立即扔掉它。

Long Answer

长答案

• Seriously? I am going to fry my computer by doing something that USB was explicitly designed for right from the beginning (hot-plugging)? Surely a computer does not suffer damage just because a data transfer fails.

  认真吗 我将通过一开始就专门为USB设计明确的功能(热插拔)来炸计算机。 当然，仅由于数据传输失败，计算机就不会遭受损坏。

Will you fry your whole computer? Most likely no. Do you increase the risk—even on a slight level—of damaging a USB port by unplugging the hard drive while it is active? I would say yes. The risk mainly comes from something like static electricity being generated between you, the computer, the USB cable and the drive port. And since the hard drive is powered and connected to some level of grounding, it becomes an attractive path for a stray static charge as explained in this blog post on the Premium USB Blog:

你会炸整个电脑吗？ 很可能没有。 通过在硬盘驱动器处于活动状态时拔出其电源，是否会增加USB端口损坏的风险(甚至是很小的风险)？ 我会说是的。 该风险主要来自您，计算机，USB电缆和驱动器端​​口之间产生的静电等。 而且，由于硬盘驱动器已通电并已连接到一定程度的接地，因此它成为杂散静电的诱人路径，如Premium USB Blog上的此Blog文章所述 ：

• ESD damage to your USB drives or ports can cause latency failures that will slow down your data transmission following static shock. Your port or device could also face more severe damage that would essentially fry it and cause it not to work at all. It could also shorten its overall lifespan. ESD can occur under simple circumstances—plugging and unplugging or flipping a nearby switch.ESD损坏USB驱动器或端口可能会导致延迟故障，从而在静电冲击后减慢数据传输速度。 您的端口或设备还可能面临更严重的损坏，从根本上将其炸开并导致其根本无法工作。 它还可能会缩短其整体寿命。 ESD可能会在简单的情况下发生-插拔附近的开关。
• Before you alarmingly back away from your computer, be comforted by the fact that the average computer user will not necessarily have to worry about it happening. However, it is still important to know about it in case you ever find yourself in a situation where ESD may occur. The odds of static shock increase once you add computer system upgrades, USB hard drives, graphics cards and other heavy duty peripherals.在您惊慌地离开计算机之前，请为普通计算机用户不必担心它发生的事实感到欣慰。 但是，了解这一点仍然很重要，以防万一您可能会发生ESD。 一旦添加了计算机系统升级，USB硬盘驱动器，图形卡和其他重型外围设备，静电冲击的几率就会增加。
• Because USB ports are hot pluggable, they need protection against static shock. With USB 2.0 data transfer rates up to 480Mbps and USB 3.0 at 5Gbps, these speeds are fast enough to spark interruptions in the signals. Many USB hubs are protected from ESD up to 2kV, but that is not always enough.由于USB端口是可热插拔的，因此需要保护以防静电冲击。 凭借高达480Mbps的USB 2.0数据传输速率和5Gbps的USB 3.0，这些速度足够快，足以引发信号中断。 许多USB集线器都具有高达2kV的ESD保护，但这并不总是足够的。

But again the risk is slight but—as that article explains—the risk does exist on some level.

但是同样，风险很小，但正如该文章所解释的那样，该风险确实存在一定程度。

Another risk is gyroscopic inertia that stems from the hard drive itself still spinning while you disconnect it. I have actually lost two external 3.5″ hard drives because I unmounted them, disconnected them, and grabbed them too quickly while the hard drives themselves were still spinning. The disorientation from me lifting one way but the gyroscopic inertia from spinning platters pulling in another direction resulted in me losing my grip on the enclosure and the hard drive crashing down onto the floor and basically making it unusable. But again, this is an edge risk.

另一个风险是陀螺仪惯性，它是由于硬盘驱动器本身在断开连接时仍在旋转而引起的。 实际上，我丢失了两个外部3.5英寸硬盘驱动器，因为在硬盘驱动器本身仍在旋转时，我将它们卸下，断开连接并以太快的速度抓住它们。 我从一个方向上迷失了方向，但旋转的盘片向另一个方向拉动了陀螺仪的惯性，这使我失去了对机箱的抓地力，硬盘驱动器坠落到了地板上，基本上使它无法使用。 但这又是一个边缘风险。

If you ask me, overwrought details like this in the manuals are not warning you of a common risk as much as they are limiting the hard drive manufacturer’s liability if somehow your data is lost—or the hard drive dies—and you end up complaining to the manufacturer. The idea is you would conceivably call up tech support, they would ask you what you did, you might tell them you disconnected the hard drive in the middle of a transfer and then they might say, “Sorry, but we do not cover that.”

如果您问我，手册中像这样的过度使用的细节并不会警告您存在共同的风险，就像它们在某种程度上丢失了数据(或硬盘驱动器死机)而限制了硬盘驱动器制造商的责任，最终您抱怨生产厂家。 可能的想法是，您可能会打电话给技术支持，他们会问您您做了什么，您可能会告诉他们您在传输过程中断开了硬盘驱动器的连接，然后他们可能会说：“对不起，但我们不涵盖。 ”

Remember, much like an End-User License Agreement (EULA), the main purpose of such documentation is not to make sure you read it as much as it is in the manufacturer’s best interest to make sure they can claim you were provided these warnings if something goes wrong from a legal standpoint.

请记住，就像最终用户许可协议(EULA)一样，此类文档的主要目的不是确保您阅读了尽可能多的内容，以符合制造商的最大利益，以确保他们可以在收到警告时要求您提供这些警告。从法律的角度来看有些问题。

Also, just a clarification on this point:

另外，只需澄清一下：

• I am going to fry my computer by doing something that USB was explicitly designed for right from the beginning (hot-plugging)?

  我将通过一开始就专门为USB设计明确的功能(热插拔)来炸计算机。

The idea that USB devices can be hot-plugged into the system simply means the USB connection is hot-pluggable, but how the devices react beyond that basic connection (if hot-plugged) is entirely a different issue.

可以将USB设备热插到系统中的想法只是意味着USB连接是可热插拔的，但是超出基本连接(如果是热插拔)的设备的React方式则完全不同。

For example, I just updated my iPhone while writing this post and I had it connected to my Mac Mini via a USB cable. Sure, I could have unplugged the USB cable in the middle of the update and what would have happened? My computer would be fine and my iPhone would technically be fine from a physical standpoint, but if I unplugged it at the perfectly wrong moment, I could have bricked my iPhone.

例如，在撰写本文时，我刚刚更新了iPhone，并通过USB电缆将其连接到Mac Mini。 当然，我可以在更新过程中拔下USB电缆，那会发生什么？ 从物理角度来看，我的计算机会很好，而从技术上来说我的iPhone会很好，但是如果我在完全错误的时刻拔掉它，那我可能会为我的iPhone涂砖。

A device being hot-pluggable simply means that the device can be connected without having to completely power down the main system to connect it or use a device probe like those SCSI probe control panels almost every Mac OS installation had back in the pre-Mac OS X days of the operating system.

可热插拔的设备只是意味着可以连接该设备，而无需完全关闭主系统的电源即可进行连接或使用诸如SCSI探针控制面板之类的设备探针，几乎所有Mac OS安装都可以在Mac之前的操作系统中使用X天的操作系统。
