Figure 140. 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, 256 sectors will be transferred.
Sector Number
This 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. (L = 1)
R
This indicates the retry bit
,
but this bit is ignored.
