You can eject an SD from a slot-in DVD drive…
Just in case you ever wonder how to “eject” an SD card from a slot-in DVD drive like the one found in an Apple iMac. Yes, I know, why would you? Well, in case you end up here googling how to, you already know why. This post here is just to note that a 2 mm. thick ruler can make the trick.
This tool makes the trick!
Insert it as deep as the SD card length and a bit more and then slide it from top to bottom. You should be touching it now, otherwise your card decided to go for a free tour inside the DVD charger. In that case you might want to rotate your iMac 90ยบ clockwise and let the gravity position your card in the desired location :-). Just don’t expect it to fall magically and also avoid shaking it… it won’t fall. The ruler procedure works better and the DVD drive shouldn’t get damaged by it. No responsibility assumed here in case it does!
Good luck with it!
P.S.: No, I won’t disclose how and why I found out this procedure.
P.S.2: The procedure might be useful as well to eject other strange bodies from your DVD drives. Just avoid inserting the ruler too deep inside it or you might end up breaking it or even worse: With a couple of strange bodies inside!
