What protects the internal components of a hard disk drive (HDD) from dust particles?

• A. Filter
• B. Internal fan
• C. Sealed metal housing
• D. Preventive maintenance

Answer: (C)

The protection of internal components in a hard disk drive (HDD) from dust particles is primarily achieved through a sealed metal housing. This design feature ensures that the sensitive internal mechanisms, including the platters and read/write heads, are securely enclosed, preventing any external contaminants, such as dust and dirt, from entering the drive. HDDs operate in a very precise environment, and any foreign particles could significantly impair their function, potentially leading to data loss or hardware failure. The sealed design maintains an optimal environment, allowing the drive to operate safely and effectively without interference from external factors. While filters and preventive maintenance might play a role in the overall longevity of a drive and the prevention of dust accumulation, it's the sealed metal housing that directly provides the necessary barrier against the intrusion of dust particles. An internal fan typically serves to cool the device, which is not its primary function in keeping out contaminants.
