DVD stuck in external disc drive, which is no longer recognizable since upgrading to mojave.

Hey, thanks for responding. I saw that page actually, and tried its solutions. Unfortunately, there is no icon whatsoever since I guess Mojave just doesn't recognize that an external is even plugged in. And the D. Utility/Terminal doesn't work since the disc itself isn't seen. I actually have a friend who's still using High Sierra, so I guess I'll just have to use his MacBook and eject then. Still, it's kind of ridiculous I presumably have to resort to such means.

Hey there, thanks the suggestions. Unfortunately, nothing seems to be working. The SuperDrive is indeed directly plugged in. It makes the little spinning/reading sounds, but it never seems to fully acknowledge the disc. As much as I love Apple, and have been more-ore-less dedicated to them since I was a kid, there are quizzical policies and designs that duly frustrate me. Especially when more often than not, the motivations for making things that way are basically seclusion from other companies, and limiting what one might be able to do. The superdrive not having a pinhole eject button is a prime example. So often, their model is reliant on other aspects working perfectly, and that approach leaves the potential for many vulnerabilities and flaws.

Anyway, I suppose it is in fact possible that the problem lies within the disc itself somehow. I still don't think this is the case however, as it happened immediate.y after upgrading to Mojave, and the drive read the disc until then. It's looking like I may have to just take it in to Geek Squad, or somewhere similar. If my friend's laptop with Sierra doesn't work, I will have to resort to such means.

Ok, well that's actually reassuring about the SuperDrives working. There was another thread that basically said it was no longer compatible, with much outrage behind it. They also mentioned something about a known bug with Mojave and blank CD's/DVD's and whatnot. So, thanks for letting me know that's not the case.
