硬盘主从盘跳线图解

You may have pins on the back of your hard drive that nothing is connected to. These pins are called jumpers, and are used to enable specific types of settings. They’re not used so much with modern hard drives, except in some special circumstances.

您的硬盘驱动器背面可能没有连接任何引脚。 这些引脚称为跳线，用于启用特定类型的设置。 除非在某些特殊情况下，它们与现代硬盘驱动器的使用并不多。

If you’re under a certain age, or you just haven’t been into computer hardware for long, you’ve probably never heard of hard drive jumpers. The jumper pins are similar to the pins on the I/O plate on a motherboard. You enable particular settings by placing a jumper shunt onto specific pins—creating an electrical circuit between them. The settings these jumpers enable are hard-coded onto a drive’s programmed printed circuit board.

如果您未满一定年龄，或者只是很长时间没有接触计算机硬件，您可能从未听说过硬盘跳线。 跳线引脚与主板上I / O板上的引脚相似。 您可以通过将跳线分流器放置在特定的引脚上(在它们之间创建电路)来启用特定的设置。 这些跳线启用的设置被硬编码到驱动器的编程印刷电路板上。

So what do jumpers do? Well, not so much anymore.

那么跳线会做什么？ 好吧，不再是了。

Back before SATA became the standard interface for drives, computers used the Integrated Drive Electronics (IDE) standard. You may remember the wide, flat parallel data cables used to connect them. In a parallel ATA setup, multiple drives in a computer needed to be set up as “master” and “slave” drives, a way of identifying and prioritizing drives when you had multiple drives on a single data cable. It’s much like setting “drive 0” and “drive 1” on the bus.

在SATA成为驱动器的标准接口之前，计算机使用了集成驱动器电子(IDE)标准。 您可能还记得用于连接它们的宽而扁平的并行数据电缆。 在并行ATA设置中，需要将计算机中的多个驱动器设置为“主”驱动器和“从属”驱动器，这是一种在单个数据电缆上有多个驱动器时识别驱动器并确定优先级的方法。 就像在总线上设置“ drive 0”和“ drive 1”一样。

PCs don’t really work that way, anymore. The only communication port you’ll find on new hard drives is SATA, which offers superior bandwidth in a much smaller package. So why are the jumper pins still around? Well, most drives don’t have them at all. On those that do, they enable a few specialized settings.

PC不再真正以这种方式工作。 您可以在新硬盘上找到的唯一通信端口是SATA，它以更小的封装提供了卓越的带宽。 那么，为什么跳线仍然存在呢？ 好吧，大多数驱动器根本没有它们。 在这样做的情况下，它们会启用一些专门的设置。

Exactly what the pins do depends on your drive and its manufacturer. For example,  let you use jumpers to set the following parameters:

引脚的确切作用取决于您的驱动器及其制造商。 例如， 器使您可以使用跳线设置以下参数：

• Pins 1 and 2: Enables spread-spectrum clocking (SSC), which helps deal with excessive electromagnetic interference.
  引脚1和2：启用扩频时钟(SSC)，这有助于处理过多的电磁干扰。
• Pins 5 and 6: Limits transfer speed to 3.0 0r 1.5Gbps, depending on the model.
  针脚5和6：根据型号，将传输速度限制为3.0 0r 1.5Gbps。
• Pins 7 and 8: Enables support for the Advanced Format disk option in some older versions of Windows.
  针脚7和8：在某些旧版本的Windows中启用对“高级格式”磁盘选项的支持。

To find out precisely what the jumper pins do on your hard drive, just search “jumper pins” along with the model number and manufacturer of your drive. You’ll find the relevant support site that tells you which ones to use.

要精确找出跳线在硬盘驱动器上的作用，只需搜索“跳线针”以及驱动器的型号和制造商即可。 您会找到相关的支持站点，该站点告诉您要使用的支持站点。

Unless you have need of those specialty settings, you can safely ignore the jumper pins on your drive. It will work fine without them on pretty much any computer made in the last ten years. Most of the options above are included for the sake of backwards compatibility. If you’re and you just wanted to know what those weird pins were, now you do!

除非需要这些特殊设置，否则可以放心地忽略驱动器上的跳线针脚。 在过去十年中几乎没有任何计算机上，如果没有它们，它将运行良好。 为了向后兼容，包含了以上大多数选项。 如果您要而您只是想知道那些奇怪的销钉是什么，那么现在就来！
