I replaced Macbook optical drive with one from another macbook, (not new) and now, the discs are really hard to put in, they don't scrape, just real firm, Well, iFixit said to transfer the black L shaped tape on the underside of the drive, well my old one didn't have it, and the new one did. So I left it on, do you think the black tape raised the drive up blocking part of it? Do you think removing the tape would have lowered it and made it work? After all this work I don't really want to go in and remove the tape, idk. Thanks
