Mounting -------- The drive may be mounted in any position. Certain switching power supplies may emanate electrical noise, which can degrade the specified read error rate. For best results, orient the drive so that the PCB assembly is not adjacent to these noise sources. Twelve mounting holes, four on the bottom and four on each side, are provided for mounting the drive into an enclosure. The size and location of these holes, are identical to industry standards. Caution: Mounting screw lengths must be chosen so that no more than 0.125 inch of the screw is available to enter the frame mounting hole. The screw length, if incorrect, will damage the PCB during installation and void the warranty. The torque applied to the mounting screws should be between 9 and 12 inch-pounds. The faceplate is clipped to the front of the HDA and may be removed in installations that do not require it. Lift up on the faceplate clips and unplug the LED cable from the PCB. Air Flow Requirements --------------------- It is recommended that air flow over the drive PCBA be a minimum of 25 cubic feet per minute. The maximum temperature of the HDA cover (measured at a point centered on the cover beneath the PCB), should not be greater than 11* C above the ambient temperature (measured 1/8 inch away from the PCB). For some installations 200 LFM of air flow may be required to maintain the temperature specified. Installation Requirements ------------------------- The LXT ATA drives must operate in a temperature range between 41*F and 122*F (5*C and 50*C). The drive should be installed in applications where temperature extremes outside of this range are avoided. Caution: These requirements must be met to ensure proper functioning of the drive. If they are not met, data loss and/or permanent damage to the drive may result. The faceplate is screwed to the front of the HDA in some LXT models, and clipped to the front in others. The faceplate may be removed in installations that do not require it. Shipping -------- At power down, the heads are automatically positioned over the dedicated landing zone (nondata) on each disk surface. The automatic shipping look solenoid is also engaged at this time. Maxtor ships the drive in single and multipack shipping containers. Users can ship the drive installed when the nonoperating shock and vibration limits are not exceeded. Interface --------- This chapter describes the interface requirements of the LXT ATA drives, which are compatible with the AT-BUS. Data is transferred in a 16-bit wide parallel data path from the host to the drive. Data transfer is controlled by commands sent from the host. The drive performs all operations necessary to write data to or read data from the medium. Data read from the medium is placed in a buffer prior to being transferred to the host. This allows two drives to be connected to the host. The primary drive is designated as the master drive and the secondary drive is designated as the slave drive. The maximum cable length connecting the host and the drives is twenty four inches (0.61 meters). Interface Connector ------------------- The interface connector is a 40-pin dual-row header connector. A key for the mating cable connector is provided by the removal of pin 20. The corresponding hole on the cable connector should be plugged. The cable connector should be keyed to prevent the possibility of installing it upside down. Recommended part numbers for the mating connector and cables are shown below. Equivalent parts may be used. Connector 3M-3417-7000 (Strain Relief 3448-2040, AMP P/N 1-499506-0) Cable Flat Cable (Stranded AWG 28) 3M-3365-40 Shielded Cable Flat Cable (Stranded AWG 28) 3M-3517-40 J3 Power Connector ------------------- The four-pin DC power connector J3 is similar to AMP's MATE-N-LOOK connector, part number 350543-4, however, is surface mounted to the PCB rather than freehanginng as the AMP part is. Part numbers for the recommended mating connector and contacts are shown below. +------------+ pin 1 +12 VDC | 4 3 2 1 | pin 2 +12 V Ground Return +------------+ pin 3 + 5 V Ground Return pin 4 + 5 VDC Type of cable 18 AWG Connector AMP 1-480424-0 Contacts AMP 61173-4 (Loose Piece), AMP 350078-4 (Strip) Buffer Access ------------- The LXT products use zone density recording. This recording technique varies the number of bytes per track (Mbytes/sec) which must be read or written. The LXT ATA drives are manufactured with either 32K or 64K of buffer RAM. To confirm the buffer size of your drive, execute the IDENTIFY command. Translate Mode -------------- The drive always operates in the translate mode because it uses zoned recording techniques. The drive firmware translates logical sector requests from the host into corresponding physical sector requests. Because the host communicates with the drive using physical drive parameters, a mapping address translation is needed to fully utilize the capacity of the drive. This also makes selecting a drive type from the BIOS tables easier. The drive type selected should have a capacity equal to or less than the formatted capacity of the drive. Note: To achieve full memory capability of the LXT-535A drive, an advanced BIOS must be used. The standard BIOS allows for only 1,024 cylinders (1,024 x 16 x 63 x 512 = 528 MB). Air Filtration System --------------------- The disks and read/write heads are assembled in a Class 100 environment and then sealed within the head disk assembly (HDA). The HDA contains an absolute filter, mounted inside the casting, to provide constant internal air filtration. J4 Service Connector LXT-200A ----------------------------- Connector J4 is a service connector providing the RS-232 interface and the ability to carry the LED signal beyond the drive. The RS-232 is used to load new firmware updates to the drive. The service connector is a ten-pin part. The mating connector is a Berg 6976410 part. When an LED is connected to pin nine (+) and pin ten (-), that LED functions in the same manner as the LED which is mounted on the drive's faceplate. This is typically used in cases where the drive is mounted in a position where the drive's LED is not visible and the faceplate is removed. Pins two through four are the RS-232 lines used to down load firmware updates to the microprocessor which are then stored on the disk. Pins three (transmit data) and four (receive data) are the main communication lines. Pin two is used to debug the processor and for a non-maskable interrupt. Pins five and six are signal ground lines. Ground Connector ---------------- Logic ground and chassis ground are tied together and an insert description lug is provided for connection to system ground. ********************************************************************** F E A T U R E S ********************************************************************** MAXTOR LXT-213A/340A/535A OEM TECHNICAL MANUAL 1023789 REV. B Defect Management ----------------- A complicated flaw scan process to generate the defect list is done at the factory for every drive. As shipped from the factory, the drive is pre-formatted with all defects reassigned to spare sectors. When reassigning defect sectors, the track is laid out again so that the defect area is skipped. One-to-one interleave and skewing factors are rearranged to maintain the streaming performance. The drive is assumed to be error-free after formatting. Synchronized Spindle -------------------- The LXT ATA drives are able to synchronize their spindles together for use in disk drive arrays. This is accomplished by having all drives in the array synchronized to a common pulsed signal. This sync signal can be provided by either an external source or one of the drives. The sync signal can be transceived on either the service connector (J4 pin 8) or the ATA bus (J1 pin 28). However, at the time this manual was printed, synchronized spindle was not available on J1 pin 28. If the sync pulses are to be generated by an external source, the sync pulses should be a negative going TTL pulse with a minimum width of 2 sec and a frequency of 60 Hz +/- 0.5%. Power-Up Sequence ----------------- DC power (+5V and +12V) may be supplied in any order. Both power supplies must be present and within the tolerances of the power sensing circuit, before the spin motor will spin up. When the spindle reaches full speed, the actuator lock automatically disengages. The drive spins up and becomes ready within 8 seconds. The drive executes its recalibration sequence whenever power is applied. ********************************************************************** 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.
