I have 16MB SANDISK SD Card .and I have two question.
1. Why this SD Card can accept CMD 1 ?
2. i left shift 9 bit the sector number to SD card.
   but i got i sector correct ,and next will get all 0xff value.
   Should i shift more one bit ?

CMD 1 is not supported by SD. So, the card will be probably not 
correctly initialized from you.
