Formatting a hard drive is the process of initializing the hard drive, SSD, USB drive. The formatting process often include: low-level formatting (basic medium preparation), partitioning (make the storage device visible to OS), and high-level formatting (generate a new file system).

Disk wipe:

Also known as data erasure or data sanitization. It is the real permanent data removal process and it’s impossible to retrieve data from a wiped disk. Data wiping aims to completely destroy all data from the hard drive or other storage devices. It uses zeros and ones to overwrite data to fill into all hard disk sectors. Through this overwriting, the old data on the hard drive is unrecoverable any more. Most of the disk wipe software listed above allows you to select a specific wiping standard based on your own needs, and lets you remove all data from the device.
