I've tried all the tricks I could find to get this damn thing out. Terminal, holding click during startup, boot manager eject... It sounds like the disc is physically hitting the aluminum case of the iMac. I took it to the apple store the first time this happened and boom, ejected the first time he tried it. The thing is, my nearest apple store is a hour away, and I don't want to uninstall the SSD I put in there for warranty work if I don't have to. Any ideas on how to get it to eject? I'll probably just buy an external after this. I just want the disc out of there. Thanks.
