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 ----------+----------+------+------- 71050A | 2045 | 16 | 63 ----------+----------+------+------- 71626A/AP | 3158 | 16 | 63 ----------+----------+------+------- 71260A/AP | 2448 | 16 | 63 ----------+----------+------+------- 71084A/AP | 2105 | 16 | 63 ----------+----------+------+------- 7541A/AP | 1052 | 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 71626/71260/71084/7541-A/AP PRODUCT MANUAL #1303 REV.F 11/95 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: 71626A/AP = 6, 71260A/AP = 5, 71084A/AP = 4 and 7541A/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 in Zone 6 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 = 156 Zone 2 = 154 Zone 3 = 150 Zone 4 = 140 Zone 5 = 132 Zone 6 = 126 Zone 7 = 120 Zone 8 = 108 Zone 9 = 100 Zone 10 = 90 Data transfer rate (MBytes per second) -------------------------------------- To from media Zone 01 = 8.10 Zone 06 = 6.50 Zone 02 = 8.02 Zone 07 = 5.94 Zone 03 = 7.68 Zone 08 = 5.55 Zone 04 = 7.18 Zone 09 = 5.08 Zone 05 = 6.80 Zone 10 = 4.61 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. Installation Steps ------------------ Warning! Pre-loaded Software on Drive This Maxtor hard drive is factory configured with a 112MB partition containing Max Blast Disk Manager installation software by Ontrack Systems. Please leave this partition intact until you choose the appropriate installation option. As a precautionary measure, Maxtor recommendeds that you download a copy of the MaxBlast software to a blank diskette even if you choose an alternate high-level formatting method. Install a 40-pin ribbon connector. The striped edge of this cable represents pin 1 and must be oriented towards pin 1 at the drive connector and at the host connector. Install a DC power connector... If AT BIOS supports user programmable parameters, program System BIOS with one of these default Parameters.
