A technician is attempting to remove all data from a hard drive and make the data unrecoverable. Which of the following is MOST likely to accomplish this?

The correct answer is E. Low-level format. A low-level format (also called a zero-fill or disk wipe) overwrites every sector of the drive with zeros or random data, making the original data unrecoverable by standard forensic methods. By contrast: 'Format C: /q /x' performs a quick format that only clears the file system…

Explanation

A low-level format (also called a zero-fill or disk wipe) overwrites every sector of the drive with zeros or random data, making the original data unrecoverable by standard forensic methods. By contrast: 'Format C: /q /x' performs a quick format that only clears the file system table - the underlying data remains intact and is easily recoverable. BrtLocker is not a recognized data-destruction tool (BitLocker encrypts data but does not erase it). Parted is a Linux partition editor that does not securely wipe data. Disk repartition only changes the partition structure; the original data sectors are not overwritten and can be recovered.
