Handle the drive only by the sides of the head/disc assembly. Avoid contact with the printed circuit board, all electronic components and the interface connector. Always rest the drive on a padded antistatic surface until you mount it in the host system. 2. 2 Mounting the ST9300 family drives You can mount ST9300 family drives in any orientation. Allow a minimum clearance of 0. 030 inches (0. 76 mm) around the entire perimeter of the drive for cooling. Figure 2 on page 12 provides mounting dimensions for the ST9300 family drives. These drives conform to the industry-standard MCC directmounting specifications and require the use of MCC-compatible connectors in direct-mounting applications. The I/O connector pins may extend up to 0. 010 inches beyond the edge of the head/disc assembly. To avoid damaging the drive: · Use M3X0. 5 metric mounting screws only. · Do not insert mounting screws more than 0. 150 inches (3. 81 mm) into the mounting holes. · Do not overtighten the screws (maximum torque: 3 inch-lb). 12 ST9300 Family Product Manual, Rev.

Mounting dimensions for the ST9300 family drives ST9300 Family Product Manual, Rev. B 13 2. 3 Master/slave configuration You must establish a master/slave relationship between multiple drives attached to a single AT bus. You can configure a drive to become a master or slave by setting the master/slave jumpers, as described below and shown in Figure 3 on page 14. If only one jumper is installed or if neither jumper is installed, then the jumper settings on each drive determine whether that drive is a master or a slave. Alternatively, you can configure an ST9300 family drive as a master or slave using the cable select option. This requires a specialized daisychain cable that grounds pin 28 (CSEL) on one of its two drive connectors. [. . . ] After the Rest command is issued, the host should wait up to 10 seconds for the drive to assert INTRQ. When the drive receives a Rest command, it captures the state of the I/O registers as they existed upon completion of the previous command, then enters Rest mode. After entering Rest mode, the drive rejects any command other than a Read Drive State command with an aborted command error. The Rest mode can be cleared only by power off or reset. [. . . ]
