SETUP – MK4018GAS (HDD2170)

Caution: Your Hard Disk Drive is a precision device and even a small drop onto any surface can cause damage. Electronstatic discharge can also damage the drive. You should ground yourself prior to handling the drive.

Master/Slave Settings

Your Toshiba Hard Disk Drive can be configured as either a "Master" or "Slave" unit. 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 table before setting drive as Master or Slave.

Master configuration is obtained by setting jumpers A, B, C & D open (no jumper present). 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".
