[. . . ] We recommend that you configure your ST3630A drive as the master when used with a non-ATAcompatible drive. 2. 4. 3 Cable-select configuration If your computer and both of your drives support cable select (CSEL), you can use the cable select option to determine the master and slave. To configure your drive to use cable select, you need to install jumpers and to use a special cable-select cable as follows: · Install a jumper on pins 3 and 4 of the master/slave jumper block as shown in Figure 3 on page 13. When a jumper is installed in this position, the drive ignores the jumper installed on pins 7 and 8. · You must use an interface cable built for cable-select. To make a drive the master, attach it to the connector that has the CSEL signal line connected to pin 28. To make a drive the slave, attach it to the connector that has pin 28 unconnected (CSEL is not carried to pin 28 of that cable connector. ) Note that CSEL is grounded at the host.

Connecting cable-selected drives 2. 4. 4 Factory-test configuration Do not install jumpers on pins 5 and 6 and pins 7 and 8 at the same time. This configuration is used to test the drive at the factory. When jumpers are installed in both of these positions, the heads continuously seek back and forth across the media and the drive ignores all control signals sent by the interface. 2. 5 Optional drive activity LED The drive is available with or without the external activity LED shown in Figure 3 on page 13. This option is available for users for whom the activity display through the bus is inaccessible or inconvenient. There are two LED options: · The LED is mounted directly on the printed circuit board, or · A two-pin header is mounted on the printed circuit board for a remote LED. The anode pin of the header is nearest the edge of the PCB. 16 Medalist 630xe ATA Product Manual, September 1995 2. 6 Mounting the drive You can mount the drive in any orientation using either the bottom or the side mounting holes, as described below. Figure 5 shows the SAE dimensions for the drive. Figure 6 on page 18 shows the metric dimensions for the drive. The location of the mounting holes are different for the SAE and metric drives. Overall, the drive dimensions are the same. · SAE drives have an "S" stamped on the frame runner and accept 6-32 UNC screws. · Metric drives have an "M" stamped on the frame runner and accept M3 screws. Insert four mounting screws not more than 0. 20 inches (6 full turns) into the drive frame. Insert four mounting screws not more than 0. 13 inches (4 full turns) into the drive frame. To prevent damage to the drive: · Use only mounting screws of the correct size and length. · Lightly tighten the mounting screws--do not apply more than 6 inch-pounds of torque. Medalist 630xe ATA Product Manual, September 1995 17 Figure 5 shows the dimensions in inches. [. . . ] 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 the block containing the error is transferred. 3. 3. 6 Write Multiple command (C5H) This command (command code C5H) is similar to the Write Sectors command. Interrupts are not presented on each sector but on the transfer of a block that contains the number of sectors defined by Set Multiple Mode command. The number of sectors per block to be transferred without intervening interrupts is programmed by the Set Multiple Mode command, which must be executed before the Write Multiple command. [. . . ]
