xbox original error 09

I got a crystal xbox. The console was opened.
I think the motherboard is version 1.6
I have error 09. The ide cable is good (tested in a pc, even replaced it with a known working one).
The ide connector on the motherboard looks good too.
The hdd is WD80EB-28CGH2 and is set to cable select.

If I connect to the xbox a regular NTFS hdd i still get error 09. Is that normal?

I made a serial cable and i've dumped the eeprom. I managed to unlock the hdd with xboxhdm. it had 5 partitions. I formated whih xboxhdm usb edition. After that i locked it back, Still error 09.

Is it possible that the mother board is bad?

 

Can you set the hdd to master?

 

I've tried cable select and master. no difference.

 

I've read somewhere that it's possible that the onboard ata controller is damaged. So I heated the nvidia chip and now the console is dead.
Meanwhile I got another xbox. The board is 1.6 and it's working.
Tonight i decided to test the old dvdrom on the the new console. Guess what? Error 09.
So all the time the dvd-rom was to blame.

PS: If you connect a ntfs hdd, the error shouldn't be 09, on the good xbox i got 13.
