c) The drive sets the BSY bit .
d) For each sector (or block) of data to be transferred:
1) When the drive is ready to receive a sector (or block) of data from the host, it sets the DRQ bit and clears
the BSY bit.
2) The host writes a sector (or block) of data via the Data Register.
3) After receiving the sector (or block) , the drive clears the DRQ bit and sets the BSY bit.
