manuactured date - 20/7/2006

n instal my 31/10/2006 dvd drive to 20/7/2006 model..
it's can be working..
or wrong bios..
plz help me guyz

Hmmm.... probably wrong bios. Look at the rom firmware. If those are identical to each other, It can be used. If not, then a flashing to the new dvd mobo is required.

Not wrong bios.actually,each xbox 360 dvd drive hv a "dvd key";a string/set of number dat is unique to each xbox 360.n d mobo has d same dvd key as its dvd drive so if u swap ur dvd drive with new one,ur x360 can't detect it.yes,u can replace ur drive with new one but there r some thing u hv do 1st:
1)dump ur dvd drive "dvd key" to pc.
2)spoof d dumped "dvd key" to ur new drive.

However,both easy step only applied only if u hv same type of dvd drive;be it samsung,hitachi etc.if ur old drive is different from ur new one,u must hv a firmware dedicated to each type of drv.although it sound complicated,it actually really easy,provided u got d right tools.hope dis'll help.

thanx..
