Recommended Mounting Configuration ---------------------------------- Maxtor 7000 Series drive design allows greater shock tolerance than that afforded by larger, heavier drives. The drive may be mounted in any attitude using four size 6-32 screws with 1/8" maximum penetration and a maximum torque of 5-inch pounds. Allow adequate ventilation to the drive to ensure reliable drive operation. Air Filtration System --------------------- All 7000 Series drives are designed to operate in a typical office environment with minimal environmental control. Over the life of the drive, a 0.3 micron filter and breather filter (located within the HDA) maintain a clean environment to the heads and disks. Read/Write Electronics ---------------------- An integrated circuit mounted within the sealed enclosure (near the read/write heads) provides one of four head selection (depending on the model), read preamplification, and write drive circuitry. Read/Write Heads and Disks -------------------------- Low mass, low force read/write heads record data on two 3.5" diameter disks. Maxtor uses a sputtered thin film medium on all disks for 7000 Series drives. Drive Mechanism --------------- A brushless DC direct-drive motor rotates the spindle at 4,480 RPM ( 0.1%). The dynamically balanced motor/spindle assembly ensures minimal mechanical runout 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. Voice Coil Actuator ------------------- All 7000 Series drives employ a rotary voice coil actuator which consists of a moving coil, an E-block or actuator arm assembly, and stationary magnets. The actuator moves on a low-mass, low-friction center shaft. The low friction generated contributes to fast average access time and low power consumption. Automatic Headpark and Lock Operation ------------------------------------- Immediately following power-down, dynamic braking of the spinning disks delays momentarily and lets the heads move to an inner mechanical stop. A small fixed magnet holds the heads in place as the disk spin down. The heads are released only when power is again applied. 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 drive 0 or 1, and are selected by the drive select bit in the Drive/Head register of the task file. All Task File registers are written in parallel to both drives. The interface processor on each drive decides whether a command written to it should be executed; this depends on the type of command and which drive is selected. Only the drive selected executes the command and activates the data bus in response to host I/O reads; the drive not selected remains inactive. A master/slave relationship exists between the two drives: drive 0 is the master, and drive 1, the slave. When J20 is closed (factory default), the drive assumes the role of master; when open, the drive acts as a slave. In single drive configurations, J20 must be closed. Cable Select ------------ CSEL (cable select) is an optional feature per ATA CAM specification. Drives configured in a multiple drive system are identified by CSEL's value: - If CSEL is grounded, then the drive address is 0. - If CSEL is open, then the drive address is 1. NOTE If the Cable Select jumper (J24) is installed, the Master/Slave jumper (J20) will be ignored. Sector Address Translation -------------------------- All 7000 Series drives feature a Universal Translate Mode. In an AT-class system, the drive may be configured to any specified combination of cylinders, heads, and sectors (within the range of the drive's formatted capacity). These drives powers-up in the Translate Mode: Model Cylinders Heads Sectors 72004A/AP 3,893 16 63 71670A/AP 3,244 16 63 71336A/AP 2,595 16 63 7668A/AP 1,297 16 63 Interface Connector ------------------- All 7000 Series AT drives have a 40-pin 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). (Striped Edge = Pin 1) Buffer Segmentation ------------------- The data buffer is organized into three segments: the read buffer, the write buffer, and an micro controller scratch pad. The read segment occupies half of the buffer and operates as a circular read- ahead buffer. The write segment occupies the other half. During write operations, it contains the host write data. Commands ATA Read Buffer (E4) and ATA Write Buffer (E8) are implemented per CAM specification 4a. Read-Ahead Mode --------------- Normally, this mode is active. Following a read request, disk read- ahead begins on the first sector and continues sequentially until the buffer is full. If a read request is received during the read-ahead operation, the buffer is examined to determine if the request is in the cache. If a cache hit occurs, read-ahead mode continues without interruption and the host transfer begins immediately. ********************************************************************** F E A T U R E S ********************************************************************** MAXTOR 72004/71670/71336/7668-A/AP REFERENCE MANUAL #1333 REV.C '96 Introduction ------------ Maxtor 7000 Series AT disk drives are 1" high, 3.5" random access storage devices which incorporate an on-board AT controller. Maxtor engineers have applied recent advances in hard drive technology to the design and manufacture of these drives. High data transfer rates and fast access times make them especially well-suited to desktop and workstation applications. Defect Management Zone (DMZ) ---------------------------- Each drive model has a fixed number of spare sectors per DMZ: 72004A/AP = 6, 71670A/AP = 5, 71336A/AP = 4 and 7668A/AP = 2 all of which are located at the end of each DMZ. Upon detection of a bad sector that has been reassigned, the next sequential sector is used. The first spare sector makes up for the loss of sector 3, and so maintains the sequential order of data, with 3 spare sectors still allocated for that cylinder. This push down method assures maximum performance. In the rare occurrence that the number of reassigned bad sectors exceed the number of spare sectors allocated for that cylinder, an alternate track area of the disk is used. All models have five (5) alternate tracks per surface. Error Correction Code --------------------- On-the-fly Hardware ECC ----------------------- 41 bits, single burst, guaranteed 17 bits, double burst, guaranteed Software ECC Correction ----------------------- 113 bits, single burst, guaranteed 17 bits, five burst, guaranteed Zone Density Recording ---------------------- The disk capacity is increased with bit density management - common with Zone Density Recording. Each disk surface is divided into 10 circumferential zones. All tracks within a given zone contain a constant number of data sectors. The number of data sectors per track varies in different zones; the outermost zone contains the largest number of data sectors, and the innermost contains the fewest. Execute Drive Diagnostics ------------------------- Commands the drive to implements the internal diagnostics tests. (These tests are executed only upon command receipt; they do not run automatically at power up or after a reset.) The drive sets BSY immediately upon receiving this command. This table presents the codes and their descriptions: Note that the value in the Error register should be viewed as a unique 8 bit Code. +-----------+----------------------------------+ |Error Code | Description | +-----------+----------------------------------+ | 01 | no error detected | +-----------+----------------------------------+ | 02 | formatter device error | +-----------+----------------------------------+ | 03 | sector buffer error | +-----------+----------------------------------+ | 04 | ECC circuitry error | +-----------+----------------------------------+ | 05 | controller microprocessor error | +-----------+----------------------------------+ | 8x | slave drive failed (Note) | +-----------+----------------------------------+ Note: If a slave drive fails diagnostics, the master drive OR's 80 hex with its own status, and loads that code into the Error register. If a slave drive passes diagnostics (or a slave is absent), the master drive OR's 00 with its own status and loads that code into the Error register. EISA Type "B" and Type "F" DMA Modes ------------------------------------ Direct Memory Access (DMA) transfers improves system performance by significantly improving troughtput. Physical Configuration Sectors per track ---------------------------------------- Zone 1 = 162 Zone 2 = 156 Zone 3 = 150 Zone 4 = 140 Zone 5 = 132 Zone 6 = 126 Zone 7 = 120 Zone 8 = 108 Zone 9 = 100 Zone 10 = 94 Data transfer rate (MBytes per second) -------------------------------------- To from media Zone 01 = 8.10 Zone 06 = 6.31 Zone 02 = 7.79 Zone 07 = 5.86 Zone 03 = 7.46 Zone 08 = 5.41 Zone 04 = 6.99 Zone 09 = 5.00 Zone 05 = 6.61 Zone 10 = 4.74 Logical Block Addressing ------------------------ The Logical Block Address (LBA) mode can only be utilized into systems that support this form of translation. The cylinder, head and sector geometry of the drive, as presented to the host, differs from actual physical geometry. The host AT computer may access a drive of set parameters: number of cylinders, heads, and sectors per track, plus cylinder, head and sector addresses. However, the drive can't use these host parameters directly because of zoned recording techniques. The drive translates the host parameters to a set of logical internal addresses for data access. The host drive geometry parameters are mapped into an LBA based on this formula: LBA = (HSCA-1)+HHDAxHSPT+HNHDxHSPTxHCYA (1) = (HSCA-1)+HSPTx(HHDA+HNHDxHCYA) (2) where HSCA = Host Sector Address, HHDA = Host Head Address HCYA = Host Cylinder Address, HNHD = Host Number of Heads HSPT = Host Sectors per Track The LBA is checked for violating the drive capacity. If it does not, the LBA is converted to physical drive cylinder, head and sector values. The physical address is then used to access the data stored on the disk and other drive related operations. S.M.A.R.T. Command Set ------------------------ 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 of service. The S.M.A.R.T. sub-command comprise the ATA S.M.A.R.T. feature set that provide access to S.M.A.R.T. attribute values, attribute thresholds and other logging and reporting information. Prior to writing any S.M.A.R.T. command to the device's command register, key values must be written by the host into the device's cylinder low and cylinder high registers, or the command will be aborted. For any S.M.A.R.T. sub-command, if a device register is not specified as being written with a value by the host, then the value in that register is undefined and should be ignored by the device. the values are: KEY REGISTER 4Fh Cylinder Low (1F4h) C2hH Cylinder High (1F5h) The S.M.A.R.T. sub-commands use a single command code (BOh) and are differentiated from one another by the value placed in the feature register. In order to issue a command, the host must write the sub- command-specific code to the device's features register before writung the command code to the command register. The sub-command and their respective codes are: D8h Enable S.M.A.R.T D9h Disable S.M.A.R.T DAh S.M.A.R.T. Return Status This feature allows the host to access the status of a S.M.A.R.T. capable device by comparing all saved attribute values with their corresponding warranty failure thresholds. If no thresholds are exceeded, the drive is declared to have a positive health status. Executing this sub-comman results in all attribute values being saved to non-volatile storage on the device. DOh S.M.A.R.T. Read Attribute Value This feature returns 512 bytes of attribute information to the host. D1h S.M.A.R.T. Read Attribute Thresholds This feature returns 512 bytes of warranty failure thresholds to the host. D3h S.M.A.R.T. Save Attribute Value This feature saves the current attribute values to non-volatile storage. D2h Enable/Disable Autosave To enable this feature, set the sector count register to F1h (enable) or 0 (disable). Attribute values are automatically saved to non-volatile storage on the device after five minutes of idle time and before entering idle, sleep or standby modes. This feature is defaulted to "enabled" when S.M.A.R.T. is enabled wia the S.M.A.R.T. Enable Operations commands. The autosave feature will not impact host system performance and does not need to be disabled. The following attributes are available: ID Status Flag Definition 1 OBh Read Error Rate 3 27h Spin Time 4 32h Total Spinups 5 33h Reallocated Sectors 7 OBh Seek Error Rate 9 12h Power-On Hours A 27h Spin-up Retries C 32h Total Power-ups
