So i got everything installed and i get the xbox trying to boot 3x (i can see the fan on the gpu spinning) then it flashes red/green and no more fan spinning on gpu but it sounds like my hdd is still going. No picture at any point. I had alot of issues with soldering the D0 point and if im being honest i dont know if its soldered to a proper ground or not i put it to one of the bigger square pads on the motherboard. Also when soldering the D0 point i coudnt get any solder to stay and i couldn't really even see the point anymore so i went above it to another point and scraped off some of the solder mask that was on it and soldered there instead, i was hoping that since it was on the same trace it would work the same but i doubt it works like that. This is the exact chip i used and its a version 1.0 xbox.  Please login or register to see this link.

Hi - I have a 500GB SATA drive upgrade complete with Startech SATA to IDE connector and 80 pin IDE cable.  However, I still feel my 400 GB IDE xbox loads coin ops games quicker.  I bought a new old stock 500GB IDE drive and now I want to clone my SATA drive to my IDE Drive.  Is this possible?  I could use Chimp or could I use HDM V1.9?  I would Prefer to use HDM V1.9 but I'm not sure it would recognise a SATA drive even if it is connected using a Startech SATA to IDE - anyone shed any light on this?  Thanks
 
 

So I got a STartech Sata to IDE adapter and successfully made and locked a new SATA 500 GG hard drive using HDM v1.9.
 
i got an 80 pin cable and connected my SATA drive and sure enough it booted to the Xbox dashboard.  I had my Rocky 5 softmod files and Splinter Cell diskready to go but I can’t load Splinter Cell - I get a message reading - “Your Xbox cannot recognize this disc.  Make sure it’s an Xbox game, DVD movie, or audio CD.  Also check to see if the disc is dirty or damaged.”
 
I have tried a different dvd drive from another Xbox that I know loads the game and I get the same message.  In fact I get the same message if I try to load any other Xbox game disk.
 
Any ideas greatly appreciated
