DIAMONDMAX 1750 – INTRODUCTION SECTION 1 Introduction Maxtor Corporation Maxtor Corporation has been providing high-quality computer storage products since 1982. Along the way, we’ve seen many changes in data storage needs. Not long ago, only a handful of specific users needed more than a couple hundred megabytes of storage. Today, downloading from the Internet and CD-ROMs, multimedia, networking and advanced office applications are driving storage needs even higher.
DIAMONDMAX 1750 – INTRODUCTION Conventions If there is a conflict between text and tables, the table shall be accepted as being correct. Key Words The names of abbreviations, commands, fields and acronyms used as signal names are in all uppercase type (e.g., IDENTIFY DRIVE). Fields containing only one bit are usually referred to as the “name” bit instead of the “name” field. Names of drive registers begin with a capital letter (e.g., Cylinder High register).
PRODUCT DESCRIPTION SECTION 2 Product Description Maxtor DiamondMax™ 1750 AT disk drives are 1-inch high, 3.5-inch diameter random access storage devices which incorporate an on-board Enhanced IDE/ATA controller. High capacity is achieved by a balanced combination of high areal recording density and the latest data encoding and servo techniques. Maxtor's latest advancements in electronic packaging and integration methods have lowered the drive's power consumption and increased its reliability.
PRODUCT DESCRIPTION Product Features Functional / Interface Maxtor DiamondMax™ 1750 hard drives contain all necessary mechanical and electronic parts to interpret control signals and commands from an AT-compatible host computer. See Section 3, Product Specifications, for complete drive specifications. Zone Density Recording The disk capacity is increased with bit density management – common with Zone Density Recording. Each disk surface is divided into 16 circumferential zones.
PRODUCT DESCRIPTION Defect Management Zone (DMZ) Each drive model has a fixed number of spare sectors per drive, all of which are located at the end of the drive. Upon detection of a bad sector that has been reassigned, the next sequential sector is used. For example, if sector 3 is flagged, data that would have been stored there is “pushed down” and recorded in sector 4. Sector 4 then effectively becomes sector 3, as sequential sectors are “pushed down” across the entire drive.
PRODUCT DESCRIPTION Major HDA Components Drive Mechanism A brush-less DC direct drive motor rotates the spindle at 5,200 RPM (±0.1%). The dynamically balanced motor/spindle assembly ensures minimal mechanical run-out to the disks. A dynamic brake provides a fast stop to the spindle motor upon power removal. The speed tolerance includes motor performance and motor circuit tolerances.
PRODUCT DESCRIPTION Subsystem Configuration Dual Drive Support Two drives may be accessed via a common interface cable, using the same range of I/O addresses. The drives are jumpered as device 0 or 1 (Master/Slave), and are selected by the drive select bit in the Device/Head register of the task file. All Task File registers are written in parallel to both drives.

INSTALLATION SECTION 4 Handling and Installation Pre-formatted Drive This Maxtor hard drive has been low-level formatted at the factory. Do not use a low-level formatting program. Important Notice There are a number of system BIOS’s currently in use which do not support hard drives with more than 4095 cylinders (2.1 gigabytes). This section contains information describing the conditions which may identify this limitation.
INSTALLATION Unpacking and Inspection Retain any packing material for reuse. Inspect the shipping container for evidence of damage in transit. Notify the carrier immediately in case of damage to the shipping container. As they are removed, inspect drives for evidence of shipping damage or loose hardware. If a drive is damaged (and no container damage is evident), notify Maxtor immediately for drive disposition.
INSTALLATION Figure 4 - 2 Single Pack Shipping Container (Option A) Figure 4 - 3 Single Pack Shipping Container (Option B) Repacking If a Maxtor drive requires return, repack it using Maxtor packing materials, including the antistatic bag. Physical Installation Recommended Mounting Configuration The DiamondMax™ 1750 drive design allows greater shock tolerance than that afforded by larger, heavier drives.
INSTALLATION Drive Jumper Settings Figure 4-4 shows the valid jumper settings for the Maxtor hard drive. A spare jumper shunt is shipped between J46 and J48. Figure 4 - 4 Master/Slave Jumper Detail Mounting Drive in System Turn the computer OFF, disconnect the power cord and remove the cover. Refer to your computer user’s manual for additional information. Installing 5.25-inch Mounting Brackets Mounting brackets are only needed when the drive will be installed in a 5.25-inch drive bay.
INSTALLATION Note: The following figures are examples of typical computer systems and mounting placements. The computer system the Maxtor hard drive is being installed in may have implemented a different mounting and placement methodology. Mounting Drive in 5.25-inch Bay If the Maxtor hard drive will be mounted in a 5.25-inch bay, install it as shown in Figure 4-6 below. Figure 4 - 6 5.25-inch Installation Mounting Drive in 3.5-inch Bay If the Maxtor hard drive will be mounted in a 3.
INSTALLATION Attaching IDE Interface and Power Cables In order for your computer to recognize that the Maxtor hard drive is in the system, the IDE interface and power cables must be connected to the hard drive, the mother board or the IDE hard drive interface card. 1 Attach an available IDE interface connector to J1 (see Figure 4-8 below) on the Maxtor hard drive. This connector is keyed and will only fit in one orientation. Do not force the connector.
INSTALLATION Attaching System Cables Attach the 40-pin IDE interface cable from the Maxtor hard drive to the IDE connector on the IDE interface card. Figure 4 - 9 System Interface Card Cabling OR Attach the 40-pin IDE interface cable from the Maxtor hard drive to the IDE connector on the mother board.
INSTALLATION System Setup The following procedures are designed for systems using the DOS 5.0 (or higher) or Windows 95 operating systems. For other operating systems (e.g., OS2®, UNIX®, LINUX and Novell NetWare®), refer to the operating system user’s manual for the BIOS setting and other installation requirements Setting the BIOS (CMOS) In order for the computer system to recognize the new Maxtor hard drive, it is necessary to set the system BIOS with the correct information about the hard drive.
INSTALLATION c) If the system has an older BIOS which does not provide a UDT, set the BIOS for the Maxtor hard drive to Type 9. If this BIOS setting is used or the BIOS does not support LBA, the drive must be prepared using Max•Blast software. 3. After the drive parameters are entered, follow the SETUP program procedures to save the settings and exit the SETUP program. After changing BIOS settings, saving the values and exiting, the SETUP program should force the system to re-boot.
INSTALLATION Windows NT 4.0 Users If the cylinder reduction jumper is installed, Windows NT 4.0 will not work with MaxBlast Installation Software (ver. 9.00M or newer) and the drive capacity will be limited to 2.1 GB. If the cylinder reduction jumper is not installed, Windows NT 4.0 will work with MaxBlast. Microsoft recommends that Windows NT 4.0 only be installed on a system that has a BIOS which supports drives larger than 2.1 GB.
AT INTERFACE DESCRIPTION SECTION 5 AT Interface Description Interface Connector All DiamondMax™ 1750 AT drives have a 40-pin ATA interface connector mounted on the PCBA. The drive may connect directly to the host; or it can also accommodate a cable connection (maximum cable length: 18 inches).

HOST SOFTWARE INTERFACE SECTION 6 Host Software Interface The host communicates with the drive through a set of controller registers accessed via the host’s I/O ports. These registers divide into two groups: the Task File, used for passing commands and command parameters and the Control/Diagnostic registers. Task File Registers The Task File consists of eight registers used to control fixed disk operations.
HOST SOFTWARE INTERFACE Sector Count Register Holds the number of sectors to be sent during a Read or Write command, and the number of sectors per track during a Format command. A value of zero in this register implies a transfer of 256 sectors. A multi-sector operation decrements the Sector Count register. If an error occurs during such an operation, this register contains the remaining number of sectors to be transferred. Sector Number Register Holds the starting sector number for any disk operation.
HOST SOFTWARE INTERFACE Command Register Contains code for the command to be performed. Additional command information should be written to the task file before the Command register is loaded. When this register is written, the BUSY bit in the Status register sets, and interrupt request to the host clears; invalid commands abort. (Detailed information on interface commands is given in Section 7.

HOST SOFTWARE INTERFACE Control Diagnostic Registers These I/O port addresses reference three Control/Diagnostic registers: I/O PORT READ WRITE 3F6h Alternate Status Fixed Disk Control 3F7h Digital Input Not used Alternate Status Register Contains the same information as the Status register in the Task File. However, this register may be read at any time without clearing a pending interrupt.
HOST SOFTWARE INTERFACE Reset and Interrupt Handling Reset Handling One of three different conditions may cause a reset: power on, hardware reset or software reset. All three cause the interface processor to initialize itself and the Task File registers of the interface. A reset also causes a set of the Busy bit in the Status register. The Busy bit does not clear until the reset clears and the drive completes initialization. Completion of a reset operation does not generate a host interrupt.
INTERFACE COMMANDS SECTION 7 Interface Commands The following section describes the commands (and any parameters necessary to execute them), as well as Status and Error register bits affected.
INTERFACE COMMANDS Read Commands Read Sector(s) Reads from 1 to 256 sectors, as specified in the Command Block, beginning at the specified sector. (A sector count of 0 requests 256 sectors.) Immediately after the Command register is written, the drive sets the BSY bit and begins execution of the command. If the drive is not already on the desired track, an implied seek is performed. Once at the desired track, the drive searches for the data address mark of the requested sector.
INTERFACE COMMANDS Read DMA Multi-word DMA Identical to the Read Sector(s) command, except that 1. The host initializes a slave-DMA channel prior to issuing the command, 2. Data transfers are qualified by DMARQ and are performed by the slave-DMA channel and 3. The drive issues only one interrupt per command to indicate that data transfer has terminated and status is available.
INTERFACE COMMANDS Write Commands Write Sector(s) Writes from 1 to 256 sectors, beginning at a sector specified in the Command Block. (A sector count of 0 requests 256 sectors.) When the Command register is written, the drive sets the DRQ bit and waits for the host to fill the sector buffer with the data to be written. An interrupt is not generated to start the first buffer fill operation. Once the buffer is full, the drive resets DRQ, sets BSY, and begins command execution.
INTERFACE COMMANDS The block count consists of the number of sectors to be transferred as a block and is programmed by the Set Multiple Mode command, which must be executed prior to the Write Multiple command. When the Write Multiple command is issued, the Sector Count register contains the number of sectors requested — not the number of blocks or the block count.
INTERFACE COMMANDS Set Feature Commands Set Features Mode Enables or disables features supported by the drive. When the drive receives this command it: 1. 2. 3. 4. Sets BSY, Checks the contents of the Features register, Clears BSY and Generates an interrupt. If the value of the register is not a feature supported by the drive, the command is aborted.
INTERFACE COMMANDS Power Mode Commands Standby Immediate – 94h/E0h Spin down and do not change time out value. This command will spin the drive down and cause the drive to enter the STANDBY MODE immediately. If the drive is already spun down, the spin down sequence is not executed. Idle Immediate – 95h/E1h Spin up and do not change time out value. This command will spin up the spin motor if the drive is spun down, and cause the drive to enter the IDLE MODE immediately.
INTERFACE COMMANDS When enabling the Automatic Power Down sequence, the value placed in the Sector Count register is multiplied by five seconds to obtain the Time-out Interval value. If no drive commands are received from the host within the Time-out Interval, the drive automatically enters the STANDBY mode. The minimum value is 5 seconds.
INTERFACE COMMANDS Initialization Commands Identify Drive Allows the host to receive parameter information from the drive. When the command is received, the drive: 1. 2. 3. 4. Sets BSY, Stores the required parameter information in the sector buffer, Sets the DRQ bit and Generates an interrupt. The host may then read the information out of the sector buffer. Parameter words in the buffer follow. Note that all reserved bits or words should be zeroes.

If words 84, 85 and 86 = 0000h or FFFFh command set notification not supported. 15 = shall be cleared to zero 14 = shall be set to one 13-0 = reserved 85 Command set enabled.
INTERFACE COMMANDS Initialize Drive Parameters Enables the drive to operate as any logical drive type. The drive will always be in the translate mode because of Zone Density Recording, which varies the number of sectors per track depending on the zone. Through setting the Sector Count Register and Drive Head Register, this command lets the host alter the drive's logical configuration. As a result, the drive can operate as any equal to or less than capacity drive type.
INTERFACE COMMANDS Seek, Format and Diagnostic Commands Seek Initiates a seek to the track, and selects the head specified in the Command block. 1. 2. 3. 4. Sets BSY in the Status register, Initiates the Seek, Resets BSY and Generates an interrupt. The drive does not wait for the seek to complete before returning the interrupt. If a new command is issued to a drive during the execution of a Seek command, the drive will wait (with BSY active) for the Seek to complete before executing the new command.
INTERFACE COMMANDS S.M.A.R.T. Command Set Execute S.M.A.R.T. The Self-Monitoring Analysis and Reporting Technology (S.M.A.R.T.) command has been implemented to improve the data integrity and data availability of hard disk drives. In some cases, a S.M.A.R.T. capable device will predict an impending failure with sufficient time to allow users to backup their data and replace the drive before data loss or loss of service. The S.M.A.R.T. sub-commands (listed below) comprise the ATA S.M.A.R.T.
