jumper setting | DataRecoveryUnion.com

Toshiba’s 2.5″ hard disk drives can be configured as either master or slave units. Master configuration is used for all single drive applications, and master or slave configuration (only one of each per port) is used for two drive applications. Use the information in the following tables for information on how to set Master/Slave jumpers.

Jumper settings for Toshiba PATA drives

The following jumper information applies to Toshiba’s current line of Hard Disk Drives:
Master configuration is obtained by setting jumpers B, C & D open (no jumper). Slave configuration is obtained by setting jumpers C-D. When B-D jumper is installed, the drive is configured as cable select. If pin 28 = Low, the drive is master. If pin 28 = High, the drive is slave.

Error Messge: "DISK BOOT FAILURE".

DATARECOVERYUNION.COM15 years ago4 years ago22 mins

Problem:
Error Messge: “DISK BOOT FAILURE“, while booting the system.

Cause:
There are several causes for this error message. The boot sequence may not be properly set in the system BIOS. Another cause is the presence of non-bootable media in the floppy or CD-ROM drives. The drive may not be properly configured or detected in the system BIOS. Incorrect Jumper Settings or a defective IDE cable may also be responsible.

Resolution:

Make sure that your boot sequence is correctly set. Generally, you should set the boot sequence to boot to the floppy drive first, then the hard drive, and the CD-ROM drive last.
Check your floppy drive and CD-ROM drive for media and remove any that you find.
Verify that your drive is properly detected in the system BIOS.
Verify that your Jumper Settings are correct.
Power off the system, replace the IDE data cable and try to boot again.

Do I need to set any jumpers to configure my SATA drive?

DATARECOVERYUNION.COM15 years ago12 years ago01 mins

No jumpers need to be set to configure a SATA drive. Serial ATA connections take the guess work out of master/slave drive configuration, since the single drive point to point connection has been introduced.

The Serial ATA host automatically determines the master and slave hard drive.

Jumper Basics

DATARECOVERYUNION.COM15 years ago4 years ago02 mins

Jumpers are small metallic pins that protrude from the end of a hard disc drive or from its circuit board, as shown below. Jumpers are used to configure the hard disc drive’s options, such as defining master and slave or cable select.

Every pin set has a specific numbering scheme, which is determined by its location on the drive. As shown above left, if the pins are on the circuit board, the pin number assignments are printed on the circuit board around the pins. As shown above right and below, if the jumper pins are on the end of the hard drive, Pin 1 will always be closest to the 4-pin power connector.

Below is a jumper shunt, which is used to connect two jumper pins. Connecting two jumper pins with a shunt completes an electrical circuit and enables or disables options of the hard drive. Extra shunts may be stored on a single pin as shown below because two or more pins must be connected by the shunt to complete the circuit and enable or disable options. When the shunt is only on one pin, it is not performing any function.

Jumper settings for Seagate and Maxtor ATA hard drives

DATARECOVERYUNION.COM15 years ago4 years ago06 mins

Master or single drive. If you are installing your Seagate hard drive as the only drive in the system or if it will be the primary boot drive for the system, the jumper should be set as Cable Select. If you are connecting the drive to an older system that has a pre-UDMA Mode 3 ATA controller, or you are connecting this to a cable with a slave device that doesn’t have a cable select jumper setting, jumper the drive as Master instead by putting a jumper on the first vertical set of pins closest to the data cable.

Drive as slave

If you are installing the drive as an additional drive in your system, the drive should be set as Cable Select. If you are connecting the drive to an older system that has a pre-UDMA Mode 3 ATA controller, or you are connecting this to a cable with a master device that doesn’t have a cable select jumper setting, jumper the drive as Slave instead by removing the jumper from the drive.

Cable Select

This setting is the default setting for ATA drives. With the Cable Select jumper set, the BIOS determines whether a drive is a master or a slave by its position on the UltraATA cable. If the drive is jumpered as cable select and is connected to the black connector on the end of the cable, it is recognized as the master drive for that ATA controller. If the drive is jumpered as cable select and is connected to the grey connector on the middle of the cable, it is recognized as the slave drive for that ATA controller.

Drive as master with a non-ATA-compatible slave

On Seagate drives only, set a jumper on pins 5 and 6 and a jumper on pins 7 and 8. Use this jumper setting only if the drive does not work as a master or cable select.

Limit drive capacity (or CLJ)

Use this on computers manufactured before November 1998 when either you start up your computer and see the message, “Hard disc drive controller failure”, your computer does not recognize your newly installed hard drive, or your system stops responding during the boot process after installing this new drive.

Seagate recommends the use of newer UltraATA cables to achieve the best performance from your new Seagate hard drive. These UltraATA cables have 3 colored connectors, each connector has a specific purpose. Be sure to plug the correct connector into the correct device.

The blue connector is for your host bus adapter (using a connector on your motherboard).
The black connector at the other end is for your master device, usually the hard drive you boot from.
The gray connector is for an optional slave device if you have a second hard drive.

Other devices like CD-ROM drives, tape drives and CD burners are usually plugged into a separate cable which also connects to the motherboard.

Seagate U-Series and Barracuda ATA drive families (ie, most ATA drives above 20 GBytes) follow the jumper configuration noted below:

Maxtor (and Quantum) drives follow the jumper configuration noted below:

The drive is configured at the factory for a cable select setting. This allows the drive to assume the proper role of master or slave based on the connector used on the cable (see the UltraATA cable figure above). For the cable select setting to work properly, the cables you are using must support the cable select feature. Current UltraATA cables with the 3 colored connectors do support this feature.

How To Set The Jumper Setting On Samsung (PATA) Hard Disk Drive?

DATARECOVERYUNION.COM15 years ago10 months ago05 mins

Setting The Jumper On Your Hard Disk Drive

Use the common jumper settings for Samsung hard disk drives that are listed below. Please verify the jumper setting by checking the label on your hard disk drive.

Important: If you partitioned and formatted your hard disk drive, with the General or 32 GB pin setting, and now need to use the opposite pin setting; remember to partition and format the drive again after changing the pin settings.

Configuring your Hard Disk Drive (Master, Slave, or Cable Select) – Setting the Jumper

If this is the only HDD in your computer, set the pin setting to Master.
If this is the second HDD in your computer, set the pin setting to Slave.
If this is the second HDD in your computer, and the first drive is set to Cable Select, set the pin setting to Cable Select.
If you are replacing the HDD in your computer, set the jumper setting to match that of the drive you are replacing.

Cable Select:

This setting is the default setting for PATA/IDE hard disk drives. With the Cable Select jumper setting, the BIOS determines whether a hard disk drive is Set as Master or Set as Slave by it’s position on the UDMA cable.
If the hard disk drive jumper is set to Cable Select and is connected to the black connector on the end of the UDMA cable, it is recognized as Set as Master for that PATA controller.
If the hard disk drive jumper is set to Cable Select and is connected to the grey connector on the middle of the UDMA cable, it is recognized as Set as Slave for that PATA controller.Note:When using Cable Select, your system must meet the following conditions:
- Your systems host controller must support Cable Select.
- Your hard drives must support Cable Select.
- Your cable must support Cable Select.

Set as Master:

Use this setting if you are installing an additional hard disk drive to a single UDMA cable with a hard disk drive Set as Slave, jumper one hard disk drive to Set as Master, and the other to Set as Slave.
Use this setting if you are installing an additional hard disk drive to a single UDMA cable and the Cable Select setting is not recognized.

Set as Slave:

Use this setting if you are installing an additional hard disk drive to a single UDMA cable with a hard disk drive Set as Master, jumper one hard disk drive to Set as Master, and the other to Set as Slave.
Use this setting if you are installing an additional hard disk drive to a single UDMA cable and the Cable Select setting is not recognized.

32 GB Clip Setting:

Use this on computers manufactured before November 1998 when either you start up your computer and see the message, “Hard disk drive controller failure“, or your system stops responding during the boot process after installing a new drive. This occurs when the hard disk drive is too large for the BIOS to support.
