Jumper Settings for theInstallation of Hard Disks and

CD, CDRW, and DVD DrivesThe following information helps set the required Cable Selection settings on a hard

drive or optical drive. Each hard drive setting is used by the Computer's BIOS to tell the

system where the hard drive is located and what priority it has in relation to the other

drives. Most hard drives and computers that were manufactured after 2002 probably donot need to have the hard drive jumping settings changed - this includes all SATA

drives.

To check the hard drive jumper settings or to physically set hard drive jumpers,

continue using this document.

NOTE: This document contains a procedure that is highly technical. The person performing the procedure should have extensive computer experience working

with both hardware and software.

WARNING: The edges of metal panels can cut skin. Be careful not to slide skin along any

interior metal edge of the computer.

CAUTION: This product contains components that can be damaged by electrostatic

discharge (ESD). To reduce the chance of ESD damage, work over anoncarpeted floor, use a static dissipative work surface (such as a conductive

foam pad), and wear an ESD wrist strap connected to a grounded surface.

Location of the jumper, IDE connectors, and ribbon cablesThe jumpers for hard disk(s) and CD/DVD drives are located on the back of the drive.

The jumper is a small metal slider covered by a rectangular piece of plastic. Jumpers for

hard drives are designed to slide over and connect metal 2 pins together so that

electricity can flow between them.

Before you can use the jumpers, you must know the hard drive setting for each pair of

pins.

Pin information may be printed directly on the hard drive label, the hard drive PCA

board under the pins, or etched in the surrounding plastic or metal near the pins. Somedrives use a default setting when there is no jumper attached. The hard drive settings

can be, but are not limited to, the following:

• MS, MA, DS, 0, or M = Master or Device 0. The drive is the first drive to be

used on the cable/channel (connected to the end connector on an IDE cable).



1 - Power cable connection

2 - SATA cable and connector (90 degree type, connector type may vary)

For IDE drives, however, use an IDE ribbon cable (40 wire standard or 80 wire Ultra-

IDE or EIDE). The ribbon cable connects a hard drive or CD/DVD drive to the

motherboard. It is possible to connect up to two devices on the same ribbon cable, as

long as the cable has three connectors (one that plugs into the motherboard and two that

plug into the back of the drives).

Figure 3: Upper IDE cable connectors

1 - Slave connector (middle)

2 - Master connector (end)

Figure 4: Example of an IDE connection



1 - IDE ribbon cable and connection

2 - power cable connection

Now that you understand the hard drive setting, the channel connectors, and the cable

types, you are ready to check the jumper settings for the drives.

Jumper settings for 1 hard drive and 1 CD/DVD drive

NOTE: When using one Western Digital hard drive on one cable, it may need to be set to"Single". See hard drive documentation for details.

• Set the hard disk jumper as CS or Single. Connect the drive using the Master

connector on the primary IDE cable.

•

Set the CD/DVD drive jumper as CS. Connect the drive using the Master connector on the secondary IDE cable.

Jumper settings for 2 hard drives and 1 CD/DVD driveNOTE: If Master (MA) is selected on the first device, then the second device on the same

cable must be set to Slave (SL). If Cable Select (CS) is used on the first device,

then the 2nd device on the same cable must also use CS.

• Set the first hard disk jumper as Master (alternatively, Cable Select selection can

be used but set the 2nd hard drive to Cable Select). 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 1st hard drive). Connect the drive using the Slave


• Set the CD/DVD drive jumper as Cable Select. Connect the drive using the

Master connector on the secondary IDE cable.

If the drive is missing from Windows (as well as in disc burning software), remove all

connected USB, FireWire, and parallel devices and perform the following steps to enable

the drive in Windows:

Step 1: Checking for a CD/DVD drive name in BIOS

Make sure the drive appears in Setup. The drive must be detected in the BasicInput/Output System (BIOS) before Windows can see the drive. Check for detection

as follows:

1. Turn on the computer. When the first logo screen appears, press the F1 key

repeatedly until the BIOS Setup screen appears (on some models this key press

may be different, F2 or Del )

2. Press the F5 key, and then press the Enter key to reset the BIOS to the

defaults.

3.Use the Left and Right Arrow keys to select Main .

4. The hardware-identifying name should appear next to the list of

drives/channels.

Figure 2: Example of a DVD drive name in a BIOS screen (your computer

will probably appear different)



If the name for the drive exists, skip to Step 3: Checking for CD/DVD at a

command prompt in XP . Otherwise, continue to the next step.

Step 2: Reseating cables

If a drive name does not appear for each drive and None is listed in the BIOS, usethese steps to open the PC case and reseat the drive cables. Work on a hard flat surfaceover a non-carpeted floor.

WARNING: The edges of metal panels can cut skin. Be careful not to slide skin along anyinterior metal edge of the computer.

CAUTION: This product contains components that are easily damaged by ElectrostaticDischarge (ESD). To reduce the chance of ESD damage, work over a non-

carpeted floor, use a static dissipative work surface (like a conductive foam

pad), and wear an ESD wrist strap that is connected to a grounded surface, likethe metal frame of a PC.

1. Turn off the PC, unplug all cords from the PC, and then press the Power

button on the front of the PC for five seconds.

2. Remove the side panel.

1 - Audio connector

2 - Drive jumper settings

3 - IDE connector for the ribbon cable

4 - Power connector

4. Reinsert both cables into the back of the drive making sure that the cables fitsnugly into their connectors and there are no bent pins in the connectors. Use a

different power cable that is not in use, if possible.

5. Remove and reinsert the CD drive's ribbon cable from the connector on the

motherboard. Be careful to not dislodge other ribbon cables.

6. Replace the cover and plug in the power cord.

7. Turn on the PC and re-check to see if the drive is listed in the BIOS (as wasdone at the beginning of this section). Do one of the following actions

depending on what is listed in the BIOS:

o If the drive name appears in Secondary Master, Secondary Slave, or

Primary Slave, the drive is now recognized by the BIOS. Exit the BIOSand let the PC start into Windows.



If Windows recognizes the drive, you are done.

If Windows does not recognize the drive, continue to the next

step.

o If the drive name still does not show up in Secondary Master,

Secondary Slave, or Primary Slave of the Main BIOS screen, the PCneeds to be serviced, the cable replaced, or the drive replaced.

o If the drive name appears in the Primary IDE section or the hard

drive name is now missing, the IDE cable is bad or the drive settings

are wrong. Replace the IDE cable and connect it according to the drive

jumper settings . That is, if the small rectangular connector (the jumper)on the drive is set to MS (Master), connect the master end of the IDE

cable into the back of the drive. If the jumper is set to SL (Slave), use

the slave connector on the cable. If the drive is set to CS (Cable Select),you can connect using either connector on the cable.

PC and then reinstall the CD writing software using the HP or Compaq application

recovery software or by using Compaq's quick restore.

For complete steps, refer to the previous section: The CD/DVD writing software doesnot recognize the original CD/DVD writer drive .

Step 10: Recovering the system

Recover the system. If you do not know how to recover the system, use one of the

following support documents:

• Pavilion: Performing a System Recovery in Windows XP

• Pavilion: Performing a System Recovery in Windows 98 and Me

• Presario: How to Perform a System Recovery . If your Presario computer came with quick restore discs, insert the first disc into the top CD or DVD

drive, restart the computer, and follow the onscreen instructions.

When done, double-click My Computer to see if the drive appears with the other

drives. Continue to the next Step if the drive does not appear.

Step 11: Determining if the drive hardware is bad

If the computer still cannot write to the disc, open PC Doctor to gather moreinformation and respond accordingly (not on Presario units manufactured before

2000).

1.Click Start , Run , and type the following into the Open field: pcdrw32

2.Click OK and wait for the PC Doctor window to appear.














3. Open the appropriate CD/DVD-ROM test from the list of tests (as in the

column to the left of the first menu).

4. If an error code is reported, the computer may need to be serviced. Run the

test again to confirm the error code. Use the following support document if youneed more information: Using PC Doctor

5. If, after you have tried all these steps, the drive still cannot write to

recordable discs, the drive is probably bad and should be replaced.

Setting Hard Drive Jumpers

This is a good time to examine any instructions that came with your hard drive tosee if any jumpers need to be adjusted. Jumpers are little connectors which

connect adjacent pins. They “jump” between the pins. The jumpers are probablyset fine, but it’s a good idea to check them, just in case.

The usual jumper settings for a hard drive are:

o Cable Select

o Primary

o Secondary

Cable select means that the mainboard will choose whether to make the driveprimary or secondary. Most mainboards today support cable select. And, mostdrives will have their jumpers already set to cable select. You can just have all your drives set to cable select, and the mainboard will take care of the rest.“Primary” means first and most important. Think of the primary as the one thatusually takes control of the cable and gets its way. The secondary is like a littlebrother who must usually wait.You usually want your main hard drive set as primary, or set it as cable select andhave the mainboard set it as primary. Because we know we want this hard drive

















set to primary, we read the Western Digital instructions which tell us how to set the jumper. Rather than going up and down, as it looks like it should, the jumper in thiscase goes across pins on the lower, longer line of pins. We set the jumper toprimary.Incorrectly set jumpers are a common problem when building a PC. So, double

check the orientation. Does the jumper go on the top row, bottom row, or acrossthe top and bottom rows? Does the jumper go closer to the side of the drive withthe power supply connector, or is the jumper closer to the side away from the power

connector ? Count pins on each side of the jumper. All this will help assure you havethe jumpers set as you want. Be sure to push the jumper in all the way.To remove jumpers, longer nails are handy, or you could use a small needle nosepliers (Figure 78). Be gentle. There’s no need to crush the little feller, no matter how frustrating he is to deal with.

Figure 78: Changing the jumper on the hard drive from cable select to primary

We could have left it as “cable select” and it would have worked fine.

After the jumper has been changed, the drive will appear as in Figure 79.

Figure 79: The jumper is changed

It sits across the bottom row of pins when set to primary. We learned this from theinstructions that came with the hard drive.
