What are jumper settings on a hard drive?
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.
Do SATA hard drives have jumpers?
Some SATA drives have a jumper but it’s only used to force a newer drive to run slower. SATA speeds have changed from 1.5 to 3.0 and now to 6 Gigabits per second.
What are SATA jumpers for?
hard-drive sata jumper. 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. SATA drives are one-per-channel, one-per-cable, etc.
What is the jumper and why you need it?
In a computer, a jumper is a pair of prongs that are electrical contact points set into the computer motherboard or an adapter card . When you set a jumper, you place a plug on the prongs that completes a contact. In effect, the jumper acts as a switch by closing (or opening) an electrical circuit.
How do you jumper a hard drive?
Connect the drive using the Master connector on the primary IDE cable. Set the second hard disk jumper to Slave (use the Cable Select selection if Cable Select was set on the first hard drive). Connect the drive using the Slave connector on the primary IDE cable. Set the CD/DVD drive jumper as Cable Select.
What is Spread Spectrum clocking hard drive?
Spread Spectrum Clock Generation (SSCG) is an efficient approach to reducing electro-magnetic interference emissions in many high-speed digital systems including hard disk drives. That’s because it increases the size, weight and cost of the system. …
What is the small 4 pin connector on a hard drive?
4-pin power (5.25 inch) A computer’s power supply normally provides several of these connectors, which mate to male interfaces on hard drives, CD/DVD drives, and other internal devices. Because these drives often have a 5.25 inch form factor, the power connector itself became known as a “5.25” connector.

- Red: 5V.
- Black: negative.
- Black: negative.
- Yellow: 12V.
How do you use a computer jumper?
When you set a jumper, you place a plug on the prongs that completes a contact. In effect, the jumper acts as a switch by closing (or opening) an electrical circuit. Jumpers can be added or removed to change the function or performance of a PC component. A group of jumpers is sometimes called a jumper block .

What are hard drive jumpers and how do they work?
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. 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.
What is a SATA hard drive jumper?
For example, Western Digital’s full-sized SATA hard drives let you use jumpers to set the following parameters: Pins 1 and 2: Enables spread-spectrum clocking (SSC), which helps deal with excessive electromagnetic interference. Pins 5 and 6: Limits transfer speed to 3.0 0r 1.5Gbps, depending on the model.
