Flashing your drive
Xtreme.bat automatically makes a backup of your dvd drive firmware called orig.bin and renames existing orig.bin nine times.
Plug SATA cable from DVD drive to PC. Power cable drive still connected to Xbox 360
Ensure Hitachi drive is in mode b either by two wire trick or slax linux boot cd
Go to Windows
Run Xtreme.bat batch file from a dos prompt specifing drive letter eg "xtreme.bat g"
Pause has been added after each flash, just press any key to continue.
All done!
Run Restore.bat to revert to original firmware eg "restore.bat g"

Media detection on Hitachi
Due to the Hitachi drives detection of Book-type DVD-Rom dual layer media taking longer than other types of media (you will hear click click noise, security sector read routine has not be executed at this stage!) this can cause the Xbox360 dashboard 
to timeout causing open tray prompt. This is normal operation for the Hitachi drive and has nothing to do with the security sector
read routine or any of the Xtreme firmware patches. Use the HDTV switch/HDD trick to soft reset the console (this doesnt reset the dvd drive) eliminating the timeout issue.
Unreconized disc/dirty disc error is due to incompatible media/burner/SS for use with Hitachi. Best results are found using Verbatim media and Pioneer burner.
