title: Which addressing mode to be used to access disk?
body: <p>I am learning OS development and I'm in preliminary level. I created a simple boot loader. To access other files on the disk(say HDD or USB drive), which addressing mode should I use?(CHS or LBA or INT 13h extensions).</p>
  
  <p>Which of these addressing mode is very efficient(means, can be used for most of the drive)?</p>
  
  <p>Thanks</p>
