Your IDE hard drive is not spinning up when you turn on the PC. What is the most likely problem. A. bad data cable B. incorrect jumper setting on drive C. loose molex connector D. virus E. tfad system board

The correct answer is: B. incorrect jumper setting on drive.

A jumper is a small plastic or metal device that is used to configure the settings of a computer component. On a hard drive, the jumper is used to set the drive’s master/slave configuration. If the jumper is not set correctly, the drive will not spin up.

The other options are incorrect because:

• A bad data cable can cause the drive to not be recognized by the computer, but it will not prevent the drive from spinning up.
• A loose molex connector can cause the drive to not receive power, but it will not prevent the drive from spinning up.
• A virus can cause the drive to become corrupted, but it will not prevent the drive from spinning up.
• A tfad system board is a type of motherboard that is used in some laptops. It is not related to the hard drive and would not cause the drive to not spin up.

If you are having trouble with your hard drive, the first thing you should do is check the jumper setting. If the jumper is set incorrectly, simply set it to the correct position and the drive should start spinning up. If the jumper is set correctly and the drive is still not spinning up, you may need to replace the drive.
