Does the "Full Factory Restore" function wipe the disk by writing 0s and 1s?


I´d like to sell my My Book Live 2TB. I wonder if the disk is completely overwritten with zeros and ones when I use the “Full Factory Restore” function.

Thank you,


The user manual shows that the Full Factory securely erases all drive.  No sure if drive will be zeroed, you may contact WD support to verify this.


thank you for your responce. I´ve read the mentioned entry “Note: A Quick Factory Restore formats the drive, while a Full Factory Restore securely erases the drive.” The word “securely” does not make me feel secure so perhaps I will have to contact WD support. Thank you.
