Figure		108 Write Sector(s) Command (30h/31h)

The Write Sector(s) command transfers one or more sectors from the host to the device, then the data is 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	The number of continuous sectors to be transferred. If zero is specified, then 256 sectors
LBA Low	will be transferred.
	The sector number of the first sector to be transferred. (L=0)
LBA High/Mid	In LBA mode, this register contains LBA bits 0 - 7. (L=1)
	The cylinder number of the first sector to be transferred. (L=0)
H	In LBA mode, this register contains LBA bits 8 - 15 (Mid), 16 - 23 (High). (L=1)
	The head number of the first sector to be transferred. (L=0)
R	In LBA mode, this register contains LBA bits 24 - 27. (L=1)
	The retry bit, but this bit is ignored.
Input Parameters From The Device
Sector Count	The number of requested sectors not transferred. This will be zero, unless
	an unrecoverable error occurs.
LBA Low	The sector number of the last transferred sector. (L=0)
LBA High/Mid	In LBA mode, this register contains current LBA bits 0 - 7. (L=1)
	The cylinder number of the last transferred sector. (L=0)
	In LBA mode, this register contains current LBA bits 8 - 15 (Mid), 16 - 23 (High).
H	(L=1)
	The head number of the last transferred sector. (L=0)In LBA mode, this register
	contains current LBA bits 24 - 27. (L=1)
