Write Sectors (30h/31h)
Table 137: 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.
LBA Low
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)
LBA High/Mid
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 (Mid) 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; this bit is ignored.
Input parameters from the device
Sector Count
This indicates the number of requested sectors not transferred. The Sector Count will be
zero unless an unrecoverable error occurs.
LBA Low
This indicates the sector number of the last transferred sector. (L = 0)
In LBA mode this register contains the current LBA bits 0–7. (L = 1)
