Hitachi HTS543212L9SA00 manual Write Sectors 30h/31h, Output Parameters To The Device Sector Count

The sector number of the last transferred sector. (L=0)

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). (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)

171

The number of requested sectors not transferred. This will be zero, unless an unrecoverable error occurs.

Table 136 Write Sector(s) Command (30h/31h)

The Write Sector(s) command transfers one or more sectors from t he 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
	will be transferred.
LBA Low	The sector number of the first sector to be transferred. (L=0)
	In LBA mode, this register contains LBA bits 0 - 7. (L=1)
LBA High/Mid	The cylinder number of the first sector to be transferred. (L=0)
	In LBA mode, this register contains LBA bits 8 - 15 (Mid), 16 - 23 (High). (L=1)
H	The head number of the first sector to be transferred. (L=0)
	In LBA mode, this register contains LBA bits 24 - 27. (L=1)
R	The retry bit, but this bit is ignored.
