It works. He’s talking about the original xbox not the 360. You can connect any drive to a modded xbox. It won’t read original game discs but backups play perfectly fine.
My xbox uses the SH-D162D with my low noise firmware. It’s completely silent while loading times are much better than with the original drive.
I’ll look into the LH-20A1P firmware when I have the time. Could take a while so. I never modded a Lite-On firmware and need to understand how the read speed is set.
