A Linux command-line utility to lock, unlock, and manage the hardware encryption functionality of Western Digital My Passport external drives. Written in Python 3.
WD My Passport drives support hardware encryption. New drives arrive in a passwordless state --- they can be used without locking or unlocking. After a password is set, drives become locked when they are unplugged and must be unlocked when they are plugged in to mount the volume and see its content.
This utlity can:
- Show drive status.
- Set and change the drive's password.
- Unlock an encrypted drive, given the password.
- Reset the drive in case of a lost password.
Passwords given on the command line are converted into binary password data in a mechanism intended to be compatible with WD's unlock software that is used in Microsoft Windows.
This tool was originally written by 0-duke in 2015 based on reverse engineering research by DanLukes and an implementation by DanLukes and KenMacD. crypto-universe converted this project and the underlying SCSI interface library py_sg to Python 3. JoshData updated the library to work with the latest WD My Passport device.
You'll need the Python 3 development headers to install this tool. On Ubuntu 22.04 LTS run:
sudo apt install python3 python3-dev python3-pip git
Install py3_sg via pip
sudo python3 -m pip install py3_sg
On other Linux distributions you may need a different command.
You must use sudo in this command. Usually that's a bad idea when running pip but we need to be root to access the devices. Then use pip to install the source code in this repository:
sudo pip install git+https://github.com/0-duke/wdpassport-utils
Run script as root or as a user that has permission to manage the device.
When used without any arguments, the status of the drive is shown:
$ sudo wdpassport-utils.py
[sudo] password for user:
Device: /dev/sdc
Security status: Unlocked
Encryption type: Unknown (0x31)
There are few options:
-u, --unlock Unlock
Unlock a locked drive. You will be asked to enter the unlock password. If everything is fine device will be unlocked. (To lock a drive, unplug it.)
-m, --mount Enable mount point for an unlocked device
After unlock, your operating system may still think that your device is a strange thing attached to its USB port and doesn't know how to manage it. This option forces the operating system to rescan the device and handle it as a normal external USB harddrive. This flag can be combined with -u.
-c, --change_passwd Set, change, or remove password protection
Set a password on a new drive, change the password, or remove the password (so that it does not need to be unlocked to use). To remove a password, leave the new password empty.
-e, --erase Erase/reset device
Erase (reset) the drive. This will remove the internal key associated to you password and all your data will be unaccessible. You will also lose your partition table and you will need to create a new one (you can use fdisk and mkfs or other utilities to prepare and format the drive).
-d DEVICE, --device DEVICE Device path (ex. /dev/sdb). Optional.
This tool will try to auto-detect the device path of your WD My Passport device. If you have more than one device, or if auto-detection fails, you can manually specify the device path, e.g. as /dev/sdb.
-h, --help show this help message and exit
Lists all possible arguments.
Use the tool and any of the information contained in this repository at your own risk. The tool was developed without any official documenation from Western Digital on how to manage the drive using its raw SCSI interface. We accept no responsibility.
