Superdrive no longer works under Mavericks

[Candlelight]

I have an early 2011 MBP which has had the internal optical drive removed and a second HDD added. I performed the plist edit to allow an external SuperDrive to work with my machine.

I did this edit whilst my machine was running 10.7.5, but recently I upgraded to Mavericks and - it must've been a couple of weeks after the upgrade - I finally re-attached my SuperDrive but I now get the below error:

Any ideas? I've done the SMC and PRAM resets.

Is there any extra I have to do under Mavericks? I have checked the plist and it still has the "correct" entry.

Remove the plist edit. Contact the maker of the data double kit and see what they recommend for Mavericks. Folks like OWC should have a solution for their kit.

Your plist edit was probably written over..

Yeah, I think you just need to re-do the plist edit. I used the hex-edit method myself, but I think they accomplish the same purpose and I would expect an OS upgrade to require me to re-do it.
