[. . . ] DiamondMax Plus8 20/30/40GB AT Product Manual May 13, 2005 Revision 1 Part Number: 000001876 May 13, 2005 Maxtor Corporation. This publication could include technical inaccuracies or typographical errors. Changes are periodically made to the information herein ­ which will be incorporated in revised editions of the publication. Maxtor may make changes or improvements in the product(s) described in this publication at any time and without notice. UL/CSA/VDE/TUV/RoHS UL standard 1954 recognition granted under File No. [. . . ] Support of various options in the standard are explained in the following sections. 5. 2 5. 2. 1 MECHANICAL INTERFACE Signal Cable and Connector The Maxtor DiamondMax Plus8 hard disk drive contains a 40-pin unitized connector for both signal and power connections as well as configuration jumpers. The dimensions and specifications of the unitized connector comply with Annex. The Maxtor DiamondMax Plus8 drives require the use of an 80 conductor cable (ATA/ATAPI-6, Annex. A, Figure A. 4 and description) to support the drive's Ultra DMA capability. 5. 3 5. 3. 1 5. 3. 1. 1 ELECTRICAL INTERFACE ATA Bus Interface Electrical Characteristics Signals on the ATA interface are assigned to connector pins according to Annex. A in the ATA/ATAPI-6 standard for the 80 conductor cable assembly. The signaling protocol complies with clause 9 and signal timing complies with clause 10 of the standard. The Maxtor DiamondMax Plus8 hard disk drives support all Ultra DMA Data Transfer modes (0 - 5) defined in the ATA/ATAPI-6 standard. In addition, these drives support Mode 6, and can send and receive data at the full 133MB/s transfer rate. Hosts may assert the RESET- signal for longer than the minimum. When power is applied with RESET- asserted, the Maxtor DiamondMax Plus8 disk media will not begin to spin up until RESET- is negated. This may reduce maximum current DiamondMax Plus8 20/30/40GB AT 5-1 ATA Bus Interface and ATA Commands consumption for the overall system. 5. 4 REGISTER ADDRESS DECODING The Maxtor DiamondMax Plus8 hard disk drives allow their host systems to address the full set of command and control registers as specified in clause 7 of the ATA/ ATAPI-6 standard. 5. 5 5. 5. 1 COMMAND INTERFACE General Feature Set The µProcessor, Disk Controller, and ATA Interface electronics are contained in a proprietary ASIC developed by Maxtor. 5. 5. 2 Supported Commands The Maxtor DiamondMax Plus8 hard disk drives support all the mandatory commands from the general feature set for devices not supporting the Packet command feature set. Refer to the ATA/ATAPI-6 standard for a detailed description of these commands. The IDENTIFY DRIVE command, however, is elaborated in the section "Identify Drive Command" on page 5-5. Table 5-1 lists the supported commands.

As defined in the ATA/ATAPI-6 standard. 5-4 DiamondMax Plus8 20/30/40GB AT ATA Bus Interface and ATA Commands Identify Drive Command This command allows the host to receive parameter information from the drive. When the command is received, the drive: 1. Stores the required parameter information in the sector buffer 3. Generates an interrupt The host may then read the information out of the sector buffer. Parameter words in the buffer are shown in Table 5-2. Note: All reserved bits or words should be zeroes.

[. . . ] Stepper motors used to be widely used for read/write head positioner, since they can be geared to move the head one track per step. Stepper motors are not as fast or reliable as the rotary voice coil actuators which Maxtor disk drives use. SUBSTRATE ­ The material the disk platter is made of beneath the magnetic coating. Hard disks are generally made of aluminum or magnesium alloy (or glass, for optical disks) while the substrate of floppies is usually mylar. [. . . ]
