Sorry I realize this is an old thread. But there is almost nothing else on this anywhere.
I have nearly completed this process with 2012 i5 board.
I had to relocate 1 Capacitor onto a pigtail so it would not be in the way and I ordered
an inexpensive GS41N 9.5mm but when i try to insert a disc it acts as tho the drive is not receiving power.
I'm assuming the diagnostic pin is the culprit. Thats why I am reaching out to you.
All the links in this article are dead I cant see what pin #4 is or what to do regarding it. Please respond.
Based on geeji's post that mentioned...
"Up to now, I thought this problem related only to the Mac Mini 2012, since I did not encountered it with my own AD-5960S Superdrive."
I thought about trying to order that drive if that one is not disabled by the diagnostic pin...
But would really like to have the Pin Removal info "Option" too!
Im long into this project and really cant bring myself to give up now!
Weirdly this forum puts some newer posts above vs below... See my post above^
