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
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.
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)
In LBA mode, this register contains current LBA bits 0 - 7. (L=1)
LBA
High/Mid
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)
H
The head number of the last transferred sector. (L=0)In LBA mode, this register
contains current LBA bits 24 - 27. (L=1)
