Two internal SCSI hard drives are installed in a computer and attach to a SCSI adapter. When the system powers up, neither of the drives are detected. What should be checked?
A) Termination of only the SCSI adapter and the adapter and hard drives have a unique ID.
B) Termination of both hard drives and both hard drives are set to SCSI ID 0.
C) Termination of both hard drives and that both hard drives have a unique ID.
D) Termination of both ends of the SCSI chain and that both hard drives have a unique ID.

In SCSI configuration, termination is necessary at both ends of the SCSI chain to prevent signal reflections that could disrupt data transmission. Therefore, the first step is to check the termination of both ends of the SCSI chain, which includes the SCSI adapter and the last SCSI device (in this case, the hard drives). Additionally, each SCSI device on the chain must have a unique ID to be recognized by the system. Therefore, both hard drives should also be checked to ensure that they have unique IDs assigned.
