Test the PBA

To test the PBA on your machine you will need the PBA image and a USB stick/thumb drive.

Unzip the PBA Linux: gunzip [BIOS32 | UEFI64].img.gz Windows: Use 7-zip. Transfer the PBA image to the USB stick.
Linux: dd if=[BIOS32 | UEFI64].img of=/dev/sd? (/dev/sd? is the USB stick base device node, no number)
Windows: use Win32DiskImager from sourceforge to write the image to the USB stick

Boot the USB stick, enter "debug" when asked for the passphrase and verify that it scans your system correctly identifying your OPAL disks.

The output should look something like this:
DTA LINUX Pre Boot Authorization
Please enter pass-phrase to unlock OPAL drives: *****
Scanning....
Drive /dev/nvme0 Samsung SSD 960 EVO 250GB is OPAL NOT LOCKED
Drive /dev/sda Crucial_CT250MX200SSD1 is OPAL Failed
Drive /dev/sdb Samsung SSD 850 EVO 500GB is OPAL Failed
Drive /dev/sdc ST500LT025-1DH142 is OPAL NOT LOCKED
Drive /dev/sdd Samsung SSD 850 EVO 250GB is OPAL NOT LOCKED
Drive /dev/sde Micron_1100_MTFDDAK256TBN is OPAL Unlocked

The meaning of the status messages are:

Status	Description
is OPAL NOT LOCKED	The drive either not locked or has not been set up
is OPAL Failed	An error occurred during the unlock
is OPAL Unlocked	The drive was successfully unlocked
NOT OPAL	The drive is not supported

If the PBA is correctly identifying your drives (a status other than NOT OPAL) then you should be able to use it to unlock them after you have enabled locking on your drive. If it's not you can open an issue at github and we'll try to determine what is wrong. I would suggest taking a picture of the screen so you can accurately report what the output was. You can also login to the system (user root, no password) and look at the extended messages that were stored in /tmp (cat /tmp/pbaerror.log).

Now its time to test the rescue system.
