Hey there! Some months ago, I got myself a (first gen) XBOX with the intention of softmodding it. The console would boot up, but not read discs. As far as I remember, it did spin the discs at this point. There was no error message, it just skipped to the main menu after like a minute of trying to read them.

After some research on common issues I checked all resistor networks, which were fine, and went on to replacing the capacitors. I triple-checked to get the right values and place them in the correct orientation. For reference: I got the Samsung SDG-605 (non-B) as seen in this video.

I connected the ribbon cables, checked one final time that everything is in the correct place and put the drive back into the XBOX. Boots up, but this time I see the disc is not spinning. The motor seems fine, since every time the tray closes, I can see it make a quick quarter-turn. It just won't do anything further than that. Then, as usual, it gets me to the main XBOX menu after some waiting time.

What should I do? Ideally I'd like to just get another, known working drive, but I read that the drive's control board is "married" to the mainboard and I'd have to swap it over in case of a replacement. Which seems risky, as this very board seems the most likely culprit. I'd also like to avoid to spend a hundred bucks for a whole new used XBOX. All this is especially frustrating as I only need the damn drive once to get the initial exploit working.
