| ( | B | ) | | Vibrations from the cd-rom drive |
|
| ( | C | ) | | Loose ribbon cable |
|
| ( | D | ) | | Excessive dust surrounding the drive |
|
| ( | E | ) | | HDI (Head-to-Disk Interface) |
The Correct Answer is: E
Explanation:
A grinding noise coming from the hard drive is most likely caused by an HDI situation. This occurs when a head becomes misaligned and eventually this will scratch / burn the disk making it inoperable.
