The Command Block registers contain the cylinder, head and sector number of the sector where the error
occurred and the Sector Count register contains the residual number of sectors that need to be
transferred for successful completion of the command, e.g. each block has 4 sectors, a request for 8
sectors is issued and an error occurs on the third sector. The Sector Count register contains 6 and the
address is that of the third sector.
6.1.40 Write-Sector(s) – 30H or 31H
This command writes from 1 to 256 sectors as specified in the Sector Count register. A sector count of
zero requests 256 sectors. The transfer begins at the sector specified in the Sector Number register.
When this command is accepted, the Device sets BSY, then sets DRQ and clears BSY, then waits for the
host to fill the sector buffer with the data to be written. No interrupt is generated to start the first host
transfer operation. No data should be transferred by the host until BSY has been cleared by the host. For
multiple sectors, after the first sector of data is in the buffer, BSY will be set and DRQ will be cleared.
After the next buffer is ready for data, BSY is cleared, DRQ is set and an interrupt is generated. When the
final sector of data is transferred, BSY is set and DRQ is cleared. It will remain in this state until the
command is completed at which time BSY is cleared and an interrupt is generated. If an error occurs
during a write of more than one sector, writing terminates at the sector where the error occurs. The
Command Block registers contain the cylinder, head and sector number of the sector where the error
occurred. The host may then read the command block to determine what error has occurred, and on
which sector.
6.1.41 Write-Verify – 3CH
This command is similar to the Write-Sector(s) command, except each sector is verified immediately after
being written. This command has the same protocol as the Write-Sector(s) command.
6.1.42 Wear Level – F5H
