That would wipe more than the data; it would also wipe the embedded servo information and render the drive completely useless until someone with a servowriter for that drive rescues them..... and even then, since many drives load portions of their firmware from the disk surfaces (from reserved tracks that cannot normally be overwritten), the drive may be bricked.
