A technician wants to install a secondary IDE drive which will be configured for additional user storage on the same IDE channel of the drive with the operating system. Which of the following jumper…

Placing jumpers on both MA and CS (Cable Select) positions simultaneously is an invalid configuration that would cause device detection errors.

Setting the secondary drive to MA creates two Master drives on the same channel, which is an unsupported configuration that causes both drives to fail to respond properly.

Placing jumpers on both SL and CS simultaneously is an invalid mixed configuration; the drive must be set to either Slave or Cable Select, not both at the same time.

IDE channels support two drives using a master-slave relationship. When the operating system drive is jumpered as Master (MA), the second drive sharing the same IDE cable and channel must be jumpered as Slave (SL). This configuration tells the controller which drive has priority and prevents address conflicts that would prevent both drives from being recognized.
