The correct answer is D. your computer’s floppy drive is defective.
A floppy disk drive (FDD) is a storage device that uses floppy disks to store data. Floppy disks are small, portable disks that can be used to store files, programs, and other data.
The FDD controller is a circuit board that controls the FDD. The FDD controller is responsible for reading and writing data to the floppy disk.
If the FDD controller fails, the computer will not be able to read or write data to the floppy disk. This will result in an “FDD controller Failure” error message.
The other options are not likely to cause an “FDD controller Failure” error message.
Option A: you did not set the jumper on the floppy drive to drive A. The jumper is a small plastic piece that is used to configure the floppy drive. The jumper is usually located on the back of the floppy drive. The jumper must be set to the correct position for the floppy drive to work properly. However, setting the jumper incorrectly is not likely to cause an “FDD controller Failure” error message.
Option B: you forgot to flash CMOS. CMOS is a small amount of memory that stores the BIOS settings. The BIOS is a program that is used to control the hardware on the computer. The BIOS settings are stored in CMOS. If the CMOS battery dies, the BIOS settings will be lost. This will result in the computer not being able to boot up. However, forgetting to flash CMOS is not likely to cause an “FDD controller Failure” error message.
Option C: you installed the floppy disk drive cable backward. The floppy disk drive cable is a cable that connects the floppy drive to the motherboard. The floppy disk drive cable must be installed correctly for the floppy drive to work properly. However, installing the floppy disk drive cable backward is not likely to cause an “FDD controller Failure” error message.
Option E: None of the above. None of the above options are likely to cause an “FDD controller Failure” error message.
