SETUP – MK3021GAS (HDD2181)
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".
