These are fields in the image metadata I hadn't figured out yet at that point. It's short for unknown. I should take a closer look again one of these days...

Hah! It seems I had a pending commit in my local copy implementing just this. I'll see if I can clean it up and push it, but for reference:

• unk1: Windows bus type (8 = RAID);
• unk2: maximum transfer size
• unk3: whether it was a removable device
