They’re actually jumper pins. You may 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.

What are the extra pins on a hard drive?
A jumper pin is a rectangular connector that creates a circuit between two pins. Seagate SATA drives have four pins, while Western Digital SATA drives have eight pins, with the additional pins to be used by technicians or your network administrator for powering up the drive while in standby mode.
How many pins does a HDD have?
The hard drive’s size is 7 cm × 9,5 cm excluding the pins. It seems to be 24 columns of pins with 2 rows, (24 × 2 = 48) pins total. It is a small space between two columns of pins and the other 22 columns.
What are the connectors on an HDD?
Any desktop computer hard drive has two connectors, one for power cable and other for data cable. Power cable connects a hard drive PCB (Printed Circuit Board) with computer’s power supply. Data cable connects the hard drive with a computer’s motherboard. SATA connectors (Serial ATA or S-ATA interface).
What are the jumper pins on the SATA drive used for?
On SATA-II drives, a jumper is sometimes used to set the drive into SATA-I mode for compatibility with older controllers. Show activity on this post. Some SATA drives have jumpers to enable/disable 3Gb/s functionality or other backwards compatibility items.
What are the connectors on a SATA hard drive?
SATA Connectors
- 7-Pin SATA Data Connector. 7-Pin eSATA Data Connector.
- SATA 22-Pin Data/Power to 7-Pin SATA and 4-Pin Molex. SATA 15-pin power connector to 4-pin Molex LP4 connector.
How many pins does a SATA hard drive have?
As previously mentioned, SATA data connectors typically feature seven pins – explained in the chart below. In a standard assembly, one end of the cable will be connected to the hard drive, while the other will be connected to the motherboard.
What is the 8 pin connector used for?
What is an 8-pin GPU Cable? 8-pin power connectors are found in high-end graphics cards. 8-pin connectors have 4.2mm pitch and can deliver up to 150 watts, twice the amount that a 6-pin connector is capable of.
How many connector does HDD use?
This standard also received the designations ATA, P-ATA or PATA. Something interesting is that this connector has up to 8 different versions, reaching speeds of up to 166MB / s. If something characterizes it, it is that it is a 40-pin connector with a central notch for the correct installation of the cable.
What cables do you need to connect a HDD?
You’ll need a SATA cable to connect your new hard drive to your motherboard. SATA cable with a 90 degree plug on one end. You can get different options for the plugs on either end. One end of the SATA cable will plug into your new hard drive, and the other needs to go to a SATA port on your motherboard.
What are the cables used in SSD and HDD?
The SATA (Serial Advanced Technology) cables are accessories used for newer PCs to connect SSDs, HDDs, and Optical drives to the motherboard.
Why wont my HDD pop up?
If your internal hard drive is not showing up, it might be because it is not initialized or it needs formatting. Make sure your disk is properly connected to the motherboard with the SATA cable. Your HDD might also not be visible in Windows 10 due to some BIOS settings.
Why is it important to set up the jumper first before installing the hard drive?
For IDE hard drives, it’s important to properly set the jumpers. If not properly done, your computer may not boot or the hard drive won’t be detected. If more than one device is on an IDE port, one device must be set to primary and the other set to secondary or cable select.
What is the jumper and why you need it?
In electronics and particularly computing, a jumper is a short length of conductor used to close, open or bypass part of an electronic circuit. They are typically used to set up or configure printed circuit boards, such as the motherboards of computers. The process of setting a jumper is often called strapping.
Does it matter what SATA port I use?
SATA ports are numbered starting from 0. As far as the performance goes, it does not matter which port number you use (as long as they all belong to the same version as discussed earlier). However for the sake of consistency, generally, it is preferred that the first port i.e Port number 0, be used for the boot drive.
What are the different SATA connectors?
There are three main types of SATA cable connections for computers: standard two-connection SATA cables, three-connection SATA cables, and eSATA cables.
What is the number of pins in a SATA 2.5 drive?
2.5″ SATA SSD and Slim SATA (MO-297) Connector
There are a total of 22-pins broken into 7-pins for Data and 15-pins for Power.
Are all SATA cables 7 pin?
The correct answer was 7. A SATA data cable has 7 pins. A SATA power cable has 15 pins.
What are SATA pins?
The SATA 15-pin power supply connector is one of the standard peripheral power connectors in computers. It’s the standard connector for all SATA-based hard drives and optical drives. SATA power cables protrude from the power supply unit and are meant to reside only inside the computer case.
Which is better HDD or SATA?
SATA vs HDD & HDD vs SSD
SATA drives are less expensive and more common than SSDs. However, SATA drives are also slower to boot up and slower in retrieving data than SSDs. If you’re looking for a hard drive with tons of storage space, a SATA drive may be for you, as they commonly hold terabytes of data.
How much power does a 8 pin connector provide?
150 watts
8-pin power connector can provide up to 150 watts.
