Set The Jumper Setting On Your Hard Disk Drive

The hard disk drive will be detected as 32 GB if the jumper is set to the 32 GB clip pin setting. The common jumper settings for Samsung hard disk drives are listed below. Please check the label on your hard disk drive for the correct jumper setting.

Important: Use the alternate jumper setting listed below under General Pin Setting. After changing the jumper, partition and format your hard disk drive.

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 Pin 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.

If after performing the troubleshooting procedure listed above, the full capacity of your hard disk drive is not recognized, click here for information about obtaining a system BIOS update. If you are unable to update your BIOS, another option would be to create a second partition with the remaining unallocated disk space.

Jumper settings wd800 Google Search

If this is an IDE/PATA hard drive then the jumper settings are marked on the circuit board.
MA = master
SL = slave
CS = cable select
If this hard drive is the one installed on the Primary IDE controller the the jumper has to be set to Master. If it won't boot up then the jumper needs to be set to Cable select.

If this hard drive is a second hard drive and is connected to the 2nd connector on the IDE data cable that is connected to the primary IDE controller then the jumper must be set to Slave.

If this hard drive is a second hard drive and is connected to the secondary IDE controller and there is no other drive on the IDE data cable other than this hard disk the the jumper can be set to either Master or Slave.
If there is a CD drive on this cable too then the drives on this data cable then the jumpers on each drive must be set differently, they cannot be set the same jumper setting.

Good luck.

Thanks for using FixYa.

To use the WD 800 as a master there must be no jumper attached to it.The maxtor has a diagram for the jumper and it MUST be set to slave not cable select.

Here you go

Jumpers on the newer Western Digital drives are different. If the drive is a single, then you should not have any jumpers on. If it's going to be a master and there's a slave, the jumper goes on the middle two pins of the five sets
