CompTIA 220-801 Certification Practice Test

Answer - A - If a new hard drive is not recognized, the most crucial aspect to be checked for is the jumper setting on the hard drive. The jumper setting should be chosen to either Cable Select or Slave and Master, based on where the drive is connected.

Key Takeaway: The most common jumpers on a hard drive are Cable Select, Master, and Slave. If Cable Select is chosen, the motherboard will choose whether to make the drive primary or secondary. If Master is chosen, the hard drive will function only if it connected to the primary master or secondary master. If Slave is chosen, the hard drive will function only if it connected to the primary slave or secondary slave.
