Advice 1: How to put jumper on hard drive

Optical drives and hard drives can operate in one of three modes: "Master", "Slave" and "Cable select". If the first mode it is necessary to move only one jumper on the second - often two or three. Have standard SATA drives also have jumpers, but they are intended for another.
How to put jumper on hard drive
Instruction
1
If the drive is installed in the computer before you move any jumpers, shut down the operating system, power off the computer, remove the hard drive ribbon cable and power cable after memorizing their position, and then remove the drive itself (without this you will not see it located on a sticker).
2
Check out images on the sticker. If you have a hard disk with interface IDE, this label is usually given three diagrams of the location of the jumpers: for the modes "Master", "Slave" and "Cable select". Sometimes there is a fourth illustration showing how to put the jumpers in order to artificially reduce the amount of storage to 32 gigabytes (this is necessary to work with older motherboards). In the Linux operating system to use this mode is not normally needed even when using such boards, as it runs with hard drives directly.
3
Themselves jumpers locate on the same side wall as the connectors. To determine where the the field to set the jumpers is the top, on landmarks, which are usually also shown in the figure. This landmark can be, for example, a missing conclusion.
4
Sami jumper move with the help of tiny pliers. Sometimes one storage configuration requires fewer jumpers than the other. So if you have an extra jumper, and save them, because in the future you may want to take it back.
5
In very rare cases, a sticker with a picture on the drive is missing. In this situation, report the model of the drive in a forum frequented by experts on repair of hard drives. Ask them to give the layout of the jumpers on the drive that model.
6
When on the same cable there are two devices (either hard drives or optical drives), should either one of them to select "Master" and the other "Slave", or both, select "Cable select".
7
The drives are SATA modes "Master" and "Slave" do not exist. The jumpers they have designed for other purposes. The most common jumper to reduce the data speed from 3 to 1.5 gigabits per second. They are designed to ensure compatibility hard drive on older motherboards. Sometimes there are jumpers that control power saver mode. Their purpose is almost always listed on the label of the drive.
8
Changing the position of jumpers, install the drive into place with the tab down, pin it, then connect the cables in the same way as they were connected before. Turn on the computer and verify that all drives are healthy.

Advice 2 : How to set jumpers

Jumper, also known as jumpers, are used to store information of a few bits, when it is inconvenient to use a ROM. The specified information is stored for as long as it does not change, and its modification is done mechanically.
How to set jumpers
Instruction
1
No matter which device you are going to rearrange the jumpers, be sure to unplug it. Even if their rearrangement in an enabled device, you won't break anything, the change will not take effect until restart, since reading the state of jumpers made in the moment of switching on the device.
2
As a tool to change the jumpers, use a pair of tweezers or small pliers. If after removing one of the jumper wires becomes unnecessary, put it in a container with a lid in case you need it elsewhere. If the jumpers, on the contrary, required more than it was originally, remove the extra jumper with some faulty devices: motherboard, hard drive, optical drive, etc.
3
If you want to select the mode of operation of the hard disk drive (Master, Slave, Cable select) and look at the sticker table on the housing of the drive. It shows the locations of the jumpers for all three cases. Optical drive mode is selected is simpler: it is enough to just move a jumper and its position corresponding to one of the three modes are indicated directly on the body. For the two devices are on the same train, the options are combinations of modes:- the first unit is Master, the second Slave; the first device - Slave, second Master;- both devices are Cable select.All other options will disable both devices.

Floppy latest models of jumpers. If got drive an older design, install a single jumper in the correct position for the device "B". If there are two drives located on the same cable, configure both devices the same. Some of them will be drive "A:" and a drive "B:" depends on their relative position (before or after the twisting on the loop). Direct discontnue cables without twists can be found only in computers that are not compatible with the IBM PC, they should be configured with jumpers a floppy drive as "A:" and the other as "B:".
5
On modern motherboards it is possible to meet only one jumper erase CMOS. If you need to carry out this operation, remove the jumper from pins corresponding to normal operation, move to another pair of contacts, designed to erase, hold there for about twenty seconds, and then move into place. The location of both pairs of contacts indicated in the instructions to the Board. If the appropriate jumper is not, in any case, don't erase CMOS circuit the batteries. Remove the battery, short the contacts on the Board, designed to connect, remove those contacts with a jumper wire, and then insert the battery into place.
