Write Sectors command (30h/31h) The Write Sectors command transfers one or more sectors from the host to the device. The data is then written to the disk media. The sectors are transferred through the Data Register 16 bits at a time. If an uncorrectable error occurs, the write will be terminated at the failing sector, when the auto reassign function is disable. Output Parameters To The Device Sector Count This indicates the number of continuous sectors to be transferred. If the Sector Count of zero is specified, then 256 sectors will be transferred. Sector NumberThis indicates the sector number of the first sector to be transferred. (L = 0) In LBA mode this register contains the LBA bits 0-7. (L = 1) Cylinder High/Low This indicates the cylinder number of the first sector to be transferred. (L = 0) In LBA mode this register contains the LBA bits 8-15 (Low) and bits 16-23 (High). (L = 1) H This indicates the head number of the first sector to be transferred. (L = 0) In LBA mode this register contains the LBA bits 24-27.
