Format Track (50h)
This command writes the desired head and cylinder of the selected drive with a vendor-unique data
pattern (typically 00h or FFh). The drive accepts a buffer of data from the host to follow the command
with the same protocol as the Write Sector(s) -30h command, although the information in the cache
is not used.
Identify Response (ECh)
This command allows the host to receive parameter information from the drive.
Idle (97h, E3h)
This command will cause the drive to set BSY, enter the IDLE mode, clear BSY, and generate an
interrupt. If the sector count is zero, the automatic power-down mode is disabled.
Idle Immediate (95h, E1h)
This command will cause the drive to set BSY, enter the IDLE (READ) mode, clear BSY, and
generate an interrupt.
Initialize Drive Parameters (91h)
This command will enable the host to set the number of sectors per track and the number of heads
per cylinder.
NOP (00h)
This command is mandatory for devices that implement the PACKET and TCQ feature sets. The
device will respond with command aborted. For devices that implement the TCQ feature set, the
subcommand 00h in the Feature field shall abort any outstanding queue. Subcommand codes 01h
through FFh in the Feature field shall not affect the status of any outstanding queue.
Read Buffer (E4h)
This command is optional for devices that do not implement the PACKET feature set. The command
will enable the host to read a 512-byte block of data. The Write Buffer (E8h) command should
precede the Read Buffer (E4h) command, lest the data returned be indeterminate.
Read DMA (C8h)
This command is mandatory for devices that do not implement the PACKET feature set. The
command will allow the host to read data using the DMA data transfer protocol.
Read DMA Ext (25h)
This command is mandatory for devices that implement the 48-bit Address feature set. The command
will allow the host to read data using the DMA data transfer protocol.
