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. ********************************************************************** G E N E R A L ********************************************************************** MAXTOR IDE INSTALLATION INSTALLATION PROCEDURE FOR AN IDE DRIVE --------------------------------------- 1. Install a 40 pin Data Cable ensuring that pin 1, which can be identified by the striped edge of the cable, is closest to the power connector on the drive. 2. Install a DC power cable to the back of the drive. 3. Verify the jumper configurations for Master/Slave operation (Note: Master will be the bootable drive. The slave will not be bootable.) Also make sure the existing C: drive is jumped to be the Master in a two drive system, not the only drive in the system. 4. Apply power to the computer. 4a. When memory test is complete go into your system's Standard CMOS set-up. (Note: There are various ways to get into CMOS set-up, please refer to system's manual for instructions.) 4b. If your system's BIOS supports a user programmable drive type, program the BIOS with the default parameters of your drive. If your system does not support a user programmable drive type choose parameters that closely match but do not exceed the drives MegaByte capacity. Escape from set-up then choose write to CMOS and exit. 5. Boot from a DOS diskette that has FDISK.EXE and FORMAT.COM on it. At the A> prompt type in FDISK. At the menu options select option 1 to create a DOS partition. Another menu will appear and from those options choose 1 to create a Primary DOS partition. Select yes to make 1 large partition and it will automatically become active. Then escape from FDISK. 6. At the A> prompt type in FORMAT C:/S This does a high-level format on the drive and transfers the system files in order for the drive to be bootable. (Note: IDE drives are low-level formatted from the manufacturer and only need a high-level format). To configure the drive as a slave drive repeat steps 1-4 and proceed with steps 5a. and 6a. as follows: 5a. At the C> prompt type in FDISK. When the menu options appear select option 5 to switch to the second drive. Enter fixed disk drive number 2. Then choose option 1 to create a DOS partition, then select option 1 again to create a Primary DOS partition or option 2 to create an Extended DOS partition. (Note: C and D drives will always be the Primary partitions but only the Primary partition on C: will have a status of active). 6a. Proceed with a high-level format on the drive by typing FORMAT D: (Note: Make sure the correct drive letter has been selected for format). 7. The drive is now bootable. As a test remove the DOS diskette from A and press reset to reboot the computer, a C> should be displayed, the drive is now ready for operation.
