Title: Question about a sata hard drive
Post by: zinger on May 13, 2018, 06:36:51 PM

In another post I mentioned I was interested in a WD Sata hard drive and was curious what the other plugins are besides the power and Sata plugins. You guys may call them sockets. Here is what I'm talking about. It is to the right of the aforementioned plugins. A good view is the fourth picture from the top to the left of the hard drive picture.

Are you referring to the pins that are on the right-side of the connector block?

Those aren't for a connector- they are jumper headers.

They are used for certain specific configuration features- you place a jumper block which will short between two pins.

In the case of the WD Blue in particular, they are used during certain phases of initial factory configuration. It can also be used to disable the use of spread-spectrum clocking used in the drive's logic to reduce EM emissions.
