Forum:Question about Gen. Knoxx SDU

I was wondering if I did not obtain the back pack SDU from the claptrap in the first playthrough on the General Knoxx DLC, am I able to get the SDU from the claptrap in Gen Knoxx on the second playthrough. I do know the Wikia says

"Secret Armory of General Knoxx

(Playthrough 1 -or- 2, not both) "

But was still wondering if it was possible. Thanks.
