Figure 128. 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.

This indicates the number of continuous sectors to be transferred. If the Sector
Count of zero is specified, then 256 sectors will be transferred.
In LBA mode this register contains the LBA bits 0–7. (L = 1)
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)
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. (L = 1)
