3.0 ATA interface
These drives use the industry-standard ATA task file interface that
supports 16-bit data transfers. It supports ATA programmed input/output
(PIO) modes 0, 1, 2, 3 and 4; multiword DMA modes 0, 1 and 2; and
Ultra DMA modes 0, 1, 2, 3 and 4. The drive also supports the use of
the IORDY signal to provide reliable high-speed data transfers.
You can use a daisy-chain cable to connect two drives to a single AT
host bus. For detailed information about the ATA interface, refer to the
draft of
AT Attachment with Packet Interface Extension (ATA/ATAPI-4),
NCITS T13 1153D,
subsequently referred to as the
