What is data wiping?

Wiping the data typically refers to the process of securely and permanently removing all contents stored on a disk, partition, or storage device, making it extremely hard for any users or data recovery software to recover the data.

Unlike quick format or volume deletion, data wiping involves overwriting the storage device with zeros or random data several times, making the wiped data irrecoverable. As a side note, after formatting a drive or deleting a volume, the data can still be recovered as they remain on the drive until new ones overwrite them.
