Jumper settings 3.3.1 Master/slave configuration The options jumper block shown in Figure 4 is used to configure the drive for operation. It is the 8-pin dual header between the interface connector and the power connector. Use the following settings to configure the drive as a master or a slave.
Windows XP, Windows Me, Windows 98 or newer versions are needed to support drives with capacities greater than 32 Gbytes. 3.3.4 Ultra ATA/100 cable An 80-conductor 40-pin cable is required to run Ultra DMA mode 3, mode 4 and mode 5. This cable uses even- numbered conductors connected to the ground pins to improve signal integrity.
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 0–4; multiword DMA modes 0–2, and Ultra DMA modes 0–5. 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.

The streaming commands may access any user LBA on a device. These commands may be interspersed with non-streaming commands, but there may be an impact on performance due to the unknown time required to complete the non-streaming commands. The streaming commands should be issued using a specified minimum number of sectors transferred per com- mand, as specified in word 95 of the IDENTIFY DEVICE response.

4.1.5.2.2 Read Stream DMA (2Ah) Protocol: DMA In This command reads from 1 to 65536 sectors as specified in the Sector Count register. A value of 0000h in the Sector Count register requests 65536 sectors. The RC bit indicates that the drive operate in a continuous read mode for the READ STREAM command. When RC is set to 0, the drive shall operate in normal streaming read mode.
Page 49
If the value is 0, the drive shall use the Default Command Completion Time Limit supplied with the most recent previous CONFIGURE STREAM command for this Stream type (Read or Write). If the Default Command Com- pletion Time Limit is 0, or no previous Configure Stream command was defined for this Stream type, the result is vendor specific.

SECTOR COUNT REGISTER FIELD DESCRIPTIONS LBA Low/Mid/High The address of the first uncorrectable error. DEVICE REGISTER FIELD DESCRIPTIONS This field indicates the selected device. STATUS REGISTER FIELD DESCRIPTIONS This bit shall be set to 0 indicating command completion. DRDY SE (Stream Error) This bit shall be set to one if the data contained erroneous data (even though the correct amount of data was transferred to the host).
Page 52
4.1.5.3 Write Stream DMA (3Ah) Protocol: DMA Out The Write Stream DMA command allows the host to write data using the DMA data transfer protocol. This com- mand allows for the host to specify to the device that additional actions need to be performed prior to the com- pletion of the command if the required bits are set.
Page 53
This bit specifies that all data for the specified stream shall be flushed to the media before command complete is reported. CCTL (Command Completion Time Limit) The time allowed for the current command to complete. This value is calculated as follows: CCTL = (content of the Features register Previous) * (IDENTIFY DEVICE data words (99:98)) microseconds The device shall use the Default Command Completion Time Limit supplied with the most recent previ- ous CONFIGURE STREAM command for this Stream type (Read or Write).
