Which of the following is the BEST way to sanitize a hard disk for reuse...

The best way to sanitize a hard disk for reuse to ensure the organization’s information cannot be accessed is data wiping. Data wiping is a process that overwrites the data on the hard disk with random or meaningless patterns, making it unrecoverable by any software or hardware methods. Data wiping can provide a high level of security and assurance that the organization’s information is permanently erased from the hard disk, and that it cannot be accessed by unauthorized parties or malicious actors.

Re-partitioning is not a way to sanitize a hard disk for reuse, but rather a way to organize the hard disk into different logical sections or volumes. Re-partitioning does not erase the data on the hard disk, but only changes the structure and allocation of the disk space. Re-partitioning may make the data inaccessible to the operating system, but not to other tools or methods that can scan or recover the data from the disk sectors.

Degaussing is a way to sanitize a hard disk for reuse, but only for magnetic hard disks, not solid state drives (SSDs). Degaussing is a process that exposes the hard disk to a strong magnetic field, which disrupts and destroys the magnetic alignment of the data on the disk platters. Degaussing can effectively erase the data on magnetic hard disks, but it can also damage or render unusable the electronic components of the hard disk, such as the read/write heads or circuit boards. Degaussing also does not work on SSDs, which store data using flash memory cells, not magnetic media.

Formatting is not a way to sanitize a hard disk for reuse, but rather a way to prepare the hard disk for use by an operating system. Formatting is a process that creates a file system on the hard disk, which defines how the data is stored and accessed on the disk. Formatting does not erase the dataon the hard disk, but only deletes the file system metadata and marks the disk space as available for new data. Formatting may make the data invisible to the operating system, but not to other tools or methods that can restore or recover the data from the disk sectors.
