You have just finished replacing the motherboard in your friend Ethan's computer with the same type of motherboard it originally had. You tested the motherboard by powering it on and verifying that the operating system started, and his applications were working. Now Ethan is complaining that his computer no longer recognizes his external hard drive. Which of the following is MOST likely causing the external hard drive not to function?
A. The USB front panel connector was not properly connected.
B. The computer's power supply was not connected properly.
C. Ethan's hard drive has failed.
D. The replacement motherboard does not support external hard drives.

A. The USB front panel connector was not properly connected

Explanation:

From the information given, the most likely reason causing the external hard drive not to function is that the USB front panel connector was not properly connected.

Even if the computer's power supply was not connected properly, this won't cause the external drive not to function. Also, the failure of the hard drive wouldn't be an option.

If the USB front panel connector was properly connected, then the computer will recognize his external hard drive.

no questions on whether they are allowed that right

glass wants to live in a world of super heroes and villains. he have lived all his life trying to be responsible for the creating the origin story of a super hero; he schemed and caused many incidents (many of them fatal) hoping that someday someone with superpowers would show up and save the day.

he knew himself very much. he saw himself as a villain of a real-life super hero story. he was aware of his strengths (more than smart enough for being manipulative and scheming) and weaknesses (having fragile bones and having to rely on his mind to succeed).
