220-1102 Practice Question: A company's IT policy requires that all disposed…
A company's IT policy requires that all disposed hard drives be physically destroyed to prevent data breaches. Which method has the least environmental impact while ensuring data destruction?
⚠ Common exam trap
CompTIA often tests the misconception that degaussing or overwriting is sufficient for physical destruction policies, but the key distinction is that physical destruction requires the drive to be rendered physically unusable and unrecoverable, not just magnetically or logically erased.

Correct answer & explanation
✓
Shred the hard drive using an industrial shredder and then recycle the metal fragments.
Industrial shredding physically destroys the platters into small fragments, making data recovery impossible, and the resulting metal fragments can be recycled, minimizing environmental impact. Unlike degaussing or drilling, shredding ensures complete destruction without leaving large e-waste components, and the recycling of ferrous and non-ferrous metals reduces raw material extraction.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use a degausser to erase the drive and then recycle it.
Why it's wrong here
Using a degausser to erase a hard drive employs a powerful magnetic field to scramble the data on magnetic platters, rendering the drive inoperable. While effective for data destruction on traditional HDDs, degaussing often physically damages the internal components, making the drive unsuitable for standard electronic recycling processes. This damage complicates material separation and can lead to the release of hazardous substances, increasing disposal costs and potentially violating environmental regulations rather than facilitating proper recycling.
- ✗
Drill holes through the platters and then dispose of the drive in e-waste.
Why it's wrong here
Drilling holes through hard drive platters is a physical destruction method, but it is often insufficient for complete data sanitization. Data can still reside on un-drilled sectors or fragments of the platters, potentially allowing recovery with specialized forensic techniques. Furthermore, simply disposing of the entire drilled drive in general e-waste without proper material separation misses opportunities for recycling valuable components and may not comply with environmental regulations for hazardous materials contained within the drive.
- ✓
Shred the hard drive using an industrial shredder and then recycle the metal fragments.
Why this is correct
Shredding hard drives with an industrial shredder provides the highest level of physical data destruction, reducing the drive into small, unrecognizable fragments. This method ensures that no data can be recovered, satisfying stringent IT security policies for complete sanitization. Subsequently, separating and recycling the resulting metal fragments (e.g., aluminum, steel) minimizes electronic waste, conserves resources, and aligns with environmental best practices, making it a comprehensive and compliant solution.
- ✗
Overwrite the drive with zeros multiple times and then donate it.
Why it's wrong here
Overwriting a hard drive with zeros multiple times, while a valid software-based data sanitization method, does not meet a company policy specifically requiring physical destruction. Software overwriting leaves the physical drive intact, and advanced forensic techniques *could* potentially recover residual data, especially on older drives or if not performed correctly. Additionally, donating a drive, even after overwriting, introduces security risks if the sanitization is not absolutely guaranteed, and it explicitly violates a policy mandating physical destruction for disposal.
