Zero filling
Updated: 10/07/2019 by Computer Hope
Zero filling describes a type of low-level format of a hard drive or another storage device where the device is erased by writing zeroes to every bit. It is used to thoroughly and securely erase all data, to make it impossible for data to be recovered later. Zero filling is a way to protect personal data from being stolen.
In addition to securely erasing data, zero filling can sometimes be used to fix a corrupted hard drive or a hard drive that is heavily infected with viruses. Some users zero fill a hard drive before installing a new operating system, to ensure all data is erased first and that the hard drive is fully usable.
