Page 18: Shock And Vibration
The annualized average failure rate (AFR) applies to the period prior to the expiration of component design life, and is based on failures chargeable to Maxtor. Determination of the AFR takes into account: a.) in-warranty field failure returns less quality acceptance-related failures and b.) an AFR equaling an exponentially weighted moving and average monthly failure rate multiplied by 12. -
Page 19: Emc/Emi
The CE Marking indicates conformity with the European Union Low Voltage Directive (73/23/EEC) when the disk mechanism is installed in a typical personal computer. Maxtor recommends that testing and analysis for EMC compliance be performed with the disk mechanism installed within the user's end-use application. -
Page 20: Section 4 - Handling And Installation
Electro-Static Discharge (ESD) To avoid some of the problems associated with ESD, Maxtor advises that anyone handling a disk drive use a wrist strap with an attached wire connected to an earth ground. Failure to observe these precautions voids the warranty. -

Page 34: Section 6 - Host Software Interface
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. -
Page 35: Sector Count Register
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. -
Page 36: Command Register
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;... -

HOST SOFTWARE INTERFACE Summary 6 – 37... -
Page 38: Control Diagnostic Registers
HOST SOFTWARE INTERFACE Control Diagnostic Registers These I/O port addresses reference three Control/Diagnostic registers: 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. Device Control Register Contains the software Reset bit and the Enable bit to enable interrupt requests to the host. -
Page 39: Reset And Interrupt Handling
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. -
Page 40: Interface Commands

Read Commands Read Sector(s) Read Verify Sector(s) Read Sector Buffer Read DMA Multi-word DMA Set Multiple Write Commands... -
Page 41: Read Commands
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. -
Page 42: Read Dma
INTERFACE COMMANDS Read DMA Multi-word DMA Identical to the Read Sector(s) command, except that The host initializes a slave-DMA channel prior to issuing the command, Data transfers are qualified by DMARQ and are performed by the slave-DMA channel and The drive issues only one interrupt per command to indicate that data transfer has terminated and status is available. -
Page 43: Write Commands
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. -
Page 44: Write Dma
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 —... -
Page 45: Set Feature Commands
INTERFACE COMMANDS Set Feature Commands Set Features Mode Enables or disables features supported by the drive. When the drive receives this command it: 1. Sets BSY, 2. Checks the contents of the Features register, 3. Clears BSY and 4. Generates an interrupt. If the value of the register is not a feature supported by the drive, the command is aborted. -
Page 46: Power Mode Commands
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 –... - Page 47 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.
-
Page 48: Initialization Commands
INTERFACE COMMANDS Initialization Commands Identify Drive Allows the host to receive parameter information from the drive. When the command is received, the drive: 1. Sets BSY, 2. Stores the required parameter information in the sector buffer, 3. Sets the DRQ bit and 4. - Page 49 INTERFACE COMMANDS 7 – 49...
