Figure 110. Write Sector(s) Command (30h/31h)
The Write Sectors 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.
The retry bit. If set to one, then retries are disabled. But ignored, when write
cache is enabled. (Ignoring the retry bit is in violation of ATA-3.)
R
The head number of the first sector to be transferred. (L=0)
In LBA mode, this register contains LBA bits 24 - 27. (L=1)
H
The cylinder number of the first sector to be transferred. (L=0)
In LBA mode, this register contains LBA bits 8 - 15 (Low), 16 - 23 (High).
(L=1)
Cylinder High/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)
Sector Number
The number of continuous sectors to be transferred. If zero is specified, then
256 sectors will be transferred.
