The partial block transfer is for n sectors, where n = remainder (sector count/block count). If the Read-
Multiple command is attempted before the Set-Multiple Mode command has been executed or when
Read-Multiple commands are disabled, the Read-Multiple operation is rejected with an Aborted
Command error. Disk errors encountered during Read- Multiple commands are posted at the beginning of
the block or partial block transfer, but DRQ is still set and the data transfer will take place as it normally
would, including transfer of corrupted data, if any.
Interrupts are generated when DRQ is set at the beginning of each block or partial block. The error
reporting is the same as that on a Read-Sector(s) Command. This command reads from 1 to 256 sectors
as specified in the Sector Count register. A sector counts of 0 requests 256 sectors. The transfer begins
at the sector specified in the Sector Number register.
At command completion, the Command Block registers contain the cylinder, head and sector number of
the last sector read.
If an error occurs, the read terminates at the sector where the error occurred. The Command Block
registers contain the cylinder, head and sector number of the sector where the error occurred. The flawed
data is pending in the sector buffer.
Subsequent blocks or partial blocks are transferred only if the error was a correctable data error. All other
errors cause the command to stop after transfer of the block which contained the error.
6.1.20 Read Sectors – 20H or 21H
This command reads from 1 to 256 sectors as specified in the Sector Count register. A sectors count of 0
requests 256 sectors. The transfer begins at the sector specified in the Sector Number register. When this
command is issued and after each sector of data (except the last one) has been read by the host, the
Device sets BSY, puts the sector of data in the buffer, sets DRQ, clears BSY, and generates an interrupt.
The host then reads the 512 bytes of data from the buffer.
At command completion, the Command Block registers contain the cylinder, head and sector number of
the last sector read. If an error occurs, the read terminates at the sector where the error occurred. The
Command Block registers contain the cylinder, head, and sector number of the sector where the error
occurred. The flawed data is pending in the sector buffer.
