Get the bar-coded labels, one for the front, one for the back.
Get the large square labels (for green/red stickers and temporary labels).

Load the module in a recorder.
If the bar-coded label says "HOB+0056", at PCFS prompt:
<code>
mk5=protect=off
mk5=vsn=HOB+0056
mk5=vsn?
</code>
The last command should return the label name, disk capacity (in GB) and block size (I think!).
