You are a desktop support technician for your company. All client computers run Windows XP Professional and Microsoft Office XP. A user in your company connects an external IEEE 1394 (FireWire) hard disk to his computer.

The user reports that when he attempts to use the external hard disk, the hard disk will not turn on. The user states that the hard disk is supposed to be powered by the IEEE 1394 port. He further states that he followed the directions that came with the hard disk, and that he connected the hard disk to his computer’s four-pin IEEE 1394 port by using a six-pin to four-pin adapter cable.

You need to ensure that the user can use the hard disk.
What should you instruct the user to do?

A.
Obtain an external power adapter for the hard disk.

B.
Uninstall and reinstall the device drivers supplied with the hard disk.

C.
Obtain a bus-powered IEEE 1394 hub. Connect the hard disk to the hub. Then connect the hub to the computer.

D.
Use a six-pin to six-pin cable that has a six-pin to four-pin adapter plug to connect the hard disk to the computer.
