A company is recycling old hard drives and wants to quickly reprovision the drives for reuse. Which of the following data destruction methods should the company use?

The correct answer is C. Low-level wiping. To quickly reprovision old hard drives for reuse while ensuring data destruction, low-level wiping is the most appropriate method. This process overwrites all sectors of the drive, making data irrecoverable.

Why each option

To quickly reprovision old hard drives for reuse while ensuring data destruction, low-level wiping is the most appropriate method. This process overwrites all sectors of the drive, making data irrecoverable.

ADegaussing

Degaussing uses a strong magnetic field to completely erase data on magnetic media, rendering the hard drive permanently unusable and unsuitable for reuse.

BStandard formatting

Standard formatting (quick format) only removes the file system table and marks sectors as available, leaving the actual data blocks intact and recoverable with data recovery tools.

CLow-level wipingCorrect

Low-level wiping, often referred to as secure erase, overwrites all data on a hard drive with a pattern of zeros or random data, making previous information unrecoverable. This method effectively destroys data while keeping the drive functional for reuse, which aligns with the need for reprovisioning.

DDeleting

Deleting files only marks the space as available on the file system, but the data physically remains on the drive until it is overwritten, making it easily recoverable.
