During the DMA transfer phase of a READ DMA command, the device shall provide status of the BSY bit
or the DRQ bit until the command is completed. At command completion, the command block registers
contain the cylinder, head and sector number (LBA) of the last sector read.
If an error occurs, the read terminates at the sector where the error occurred. The flawed data is pending
in the sector buffer. Subsequent sectors are transferred only if the error was a correctable data error. All
other errors cause Read-DMA to stop after transfer of the sector that contained the error.
For Ultra-DMA mode, if a CRC error is detected during transfer, the ICRC and ABRT bits of the Error
register are set at the end of the command.
6.1.18 Read Long Sector - 22h or 23h
The Read Long command performs similarly to the Read Sector(s) command except that it returns 516
bytes of data instead of 512 bytes. During a Read Long command, the device does not check the ECC
bytes to determine if there has been a data error. Only single sector read long operations are supported.
The transfer consists of 512 bytes of data transferred in word mode followed by 4 bytes of ECC data
transferred in byte mode. This command has the same protocol as the Read Sector(s) command. Use of
this command is not recommended.
6.1.19 Read-Multiple – C4H
The Read- Multiple command is similar to the Read- Sector(s) command. Interrupts are not generated on
every sector, but on the transfer of a block which contains the number of sectors defined by a Set-
Multiple command.
Command execution is identical to the Read- Sectors operation except that the numbers of sectors
defined by a Set-Multiple command are transferred without intervening interrupts. DRQ qualification of the
transfer is required only at the start of the data block, not on each sector.
The block count of sectors to be transferred without intervening interrupts is programmed by the Set-
Multiple Mode command, which must be executed prior to the Read- Multiple command. When the Read-
Multiple command is issued, the Sector Count register contains the number of sectors (not the number of
blocks or the block count) requested. If the number of requested sectors is not evenly divisible by the
block count, as many full blocks as possible are transferred, followed by a final, partial block transfer.
