To zero out a drive three times from within Windows, which command should be used?

• A. Degaussing
• B. format C: /fs:fat32/p:3
• C. diskpart > select disk 1 > clean all
• D. dd if=/dev/zero of=/dev/sda1

Answer: (B)

The process of zeroing out a drive involves overwriting the entire disk with zeros, effectively erasing all existing data. In the context of the options provided, the command that appropriately meets this requirement is the third option, which involves using Diskpart. The command "diskpart > select disk 1 > clean all" is the correct approach to zeroing out a drive. The "clean all" command in Diskpart specifically overwrites every sector of the selected disk with zeros. This not only removes the partitions but also ensures that the data is not recoverable. Moreover, this method is reliable and effective for securely wiping a drive in Windows. On the other hand, the "format C: /fs:fat32/p:3" option is not applicable here. The correct format command does not have a valid syntax for zeroing out. While formatting can erase the file system structure, it does not securely wipe the actual data in the way that a clean all operation does. The command “dd if=/dev/zero of=/dev/sda1” is a Linux command used for zeroing out a disk and is not relevant for a Windows environment, which makes it inapplicable for this context.
