In the Devices and Drives section of the main window, you should see your external hard drive. If you do a full format of your drive, you will lose all your data. A Quick initialization is just that—it quickly wipes all of the data, but not very securely.
So someone with specialized software could recover any of that data. A Full initialization wipes all of the data securely and prevents anyone else from recovering the data.

How do you put a jumper on a hard drive? Why Is Hard Drive not showing up? Another example is in some garage door remotes. Those types of remotes have to have jumpers in the same positions as the jumpers in the garage door receiver.
If even one jumper is missing or misplaced, the remote won't understand how to communicate with the garage door. Similar is a ceiling fan remote. With these types of remotes, changing where the jumpers are usually adjusts the frequency of the remote so that it can reach the device that's listening on the same frequency.
The biggest benefit of using jumpers is that a device's settings can be changed only with a physical change of the position of the jumper. The alternative is that firmware changes the settings, which makes the hardware less likely to always comply because the firmware is easily affected by software changes like unintentional glitches. You can usually move the jumper between two pins that will make it a secondary or primary drive—another option is moving it to cable select.
A group of multiple jumper pins that are collected together is often called a jumper block. Plug and Play eliminates the need to adjust jumpers on a device. However, some devices do come with instructions for manipulating the jumpers if you want to customize the settings—it's just not required like it is with lots of old hardware.

Back in the days of PATA hard drives, a person used jumpers on the drive to indicate whether the drive was the master or the slave of the channel, or to let the cable select which drive was which. To determine the default setting for your drive, look at the drive label on the top of the drive.
Change the jumper settings ONLY if you intend to use the drive in an enterprise storage environment. Default setting is disabled. See for example this. You put a jumper between two of them to limit the drive to 1. But what are the other two? As shown on this page , the other two pins plus the nearest of the pair of pins used to limit the drive speed, which is a ground make a serial port, which talks directly to the drive firmware!
