The correct answer is C. Move the jumper on the secondary drive off of master. On older PATA/IDE drives, a physical jumper on the drive configures it as Master, Slave, or Cable Select.

Explanation

On older PATA/IDE drives, a physical jumper on the drive configures it as Master, Slave, or Cable Select. If two drives on the same IDE channel are both jumpered as Master, only one will be recognized - the other is invisible to the BIOS. Moving the secondary drive's jumper to Slave (or Cable Select) resolves the conflict. Clearing BIOS settings (A) would not fix a jumper conflict. Moving the cable port (B) could help in some scenarios but is not the root cause here. S.M.A.R.T. (D) is a health monitoring feature unrelated to drive detection.
