Periodic backup of important data is always a good idea. Whenever your computer is on, there is the potential for losing data on your hard drive. This is especially true when running disk utilities or any software that directly manipulates your files. Maxtor recommends that you make a backup copy of the files on any existing hard drives. If required, this data may then be copied to the Maxtor hard drive after it has been installed in your computer. -

Page 41: 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 42: 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 43: 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;... -

Page 45: 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 and Enable bit to enable interrupt requests to the host. -
Page 46: 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 47: Section 7 - Interface Commands

Read Commands Read Sector(s) Read Verify Sector(s) Read Sector Buffer Read DMA Multi-word DMA Ultra DMA Read Multiple... -
Page 48: 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 49: 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 The drive issues only one interrupt per command to indicate that data transfer has terminated and status is available. -
Page 50: Set Multiple
INTERFACE COMMANDS Set Multiple Mode Enables the controller to perform Read and Write Multiple operations, and establishes the block count for these commands. Before issuing this command, the Sector Count register should be loaded with the number of sectors per block. The drives support block sizes of 2, 4, 8 and 16 sectors. When this command is received, the controller sets BSY and examines the Sector Count register contents. -
Page 51: Write Dma
INTERFACE COMMANDS Write Multiple Performs similarly to the Write Sector(s) command, except that: 1. The controller sets BSY immediately upon receipt of the command, 2. Data transfers are multiple sector blocks and 3. The Long bit and Retry bit is not valid. Command execution differs from Write Sector(s) because: 1. -
Page 52: 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 53: 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. - Page 54 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.
-
Page 55: 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 56 INTERFACE COMMANDS 7 – 10...
- Page 57 INTERFACE COMMANDS 7 – 11...
-
Page 58: Initialize Drive Parameters
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. -
Page 59: Seek, Format And Diagnostic Commands
INTERFACE COMMANDS Seek, Format and Diagnostic Commands Seek Initiates a seek to the track, and selects the head specified in the Command block. 1. Sets BSY in the Status register, 2. Initiates the Seek, 3. Resets BSY and 4. Generates an interrupt. The drive does not wait for the seek to complete before returning the interrupt. -
Page 60: S.m.a.r.t. Command Set
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. -
