Hi i have 2011 white macbook,i put in blank cd/dvd's and the drive spins and ejects the disc straight away.I have gone into system preferences and the cd/dvds option is set to 'ask me what to do' when opening a desk.I have also gone into utilities and found a disc repair option under permissions? it shows a Hitachi drive i guess thats the disc drive factory installed in the macbook.The drive plays original movie/cd's but cant do anything with blanks??????
