General information 

Blancco LUN Eraser enables storage administrators to securely erase individual disks or logical drives (LUNs) in active storage environments.

Also, Blancco LUN Eraser can be used to erase physical hard drives and SSDs. This document describes how to use this tool to erase internal disks from Apple computers, such as Mac Book Pro models that contain the T2 chip or those models in which it was not possible to boot from a USB boot media and Blancco Drive Eraser software.

Mac Book Pro Erase Process

Starting in 2018, Apple incorporated a security chip known as T2, in its latest models, such as Mac Book Pro, this chip provides additional security to Apple computers, for example, it provides the basis for encrypted storage APFS, secure boot among other features.

In some cases, Blancco Drive Eraser is blocked by this chip preventing loading of the eraser software. Given such a scenary, two alternatives are suggested:

Remove the disk from the computer and mount it on another computer that does not have such a chip

Use the Blancco Lun Eraser Unix tool in its version 2.3.0.

To delete the internal disk of a Mac with Blancco LUN Eraser, the following requirements must be taken into account:

The Apple computer to be deleted must have the macOS Mojave operating system installed.

Blancco Lun Eraser must be run from an external drive, i.e. an external hard drive with Mojave (latest S.O. in MAC) preloaded is required.

Connection to a Blancco Local Console from where licenses will be taken is required.

Blancco LUN licenses, quantity depends on disk size and 1 license per GB is taken.

The following describes how to install macOS on an external drive (for example, an HDD or SSD) and add Blancco LUN Eraser.

External Unity Preparation

Connect the external drive and wait for it to be detected by the computer.

Make a backup copy of all the data on the external drive that you don't want to lose.

Open Disk Utility: Go -> Utilities -> Disk Utility

Identify and select the drive, click at the top where the option Delete is located.

A menu of options will be displayed and select the APFS format.

Click on the Delete button.

Erase Internal Hard Drive Using Commands

Deleting using commands allows you to have more options when deleting, the procedure is as follows:

1. Run Terminal.

2. Execute the following comment to list the internal disks (for example / dev / disk0):

diskutil disk | grep internal

3. Unmount the internal disk with the following command (for example / dev / disk0)

diskutil unmountDisk / dev / disk0

4. Erase the internal disk (for example / dev / disk0 with the NIST 800-88 standard):

sudo ./BlanccoLUNEraser something = 16 target = / dev / disk0
