Drive 0 is the only drive for single drive installations. For dual drive installations, drive 0 is the MASTER drive and drive 1 is the SLAVE drive. The jumper block connector determines the drive logical address. Single Drive Installation ------------------------- The jumper block connector needs NO jumpers for a single drive installation. Dual Drive Installation ----------------------- For a dual drive installation, one drive must be the master and one must be the slave. Installing a jumper on pin pair Master selects the Master drive. This selects logical drive 0 (C:). Installing a jumper on pin pair Slave selects the SLAVE drive. Slave selects logical drive 1 (D:). Either drive can be a master or a slave. There cannot be 2 masters or 2 slaves. The position of the master and the slave drive on the interface cable, is not important. The jumper block should have only one jumper installed per drive. Commands and data information passes on the common 40-pin AT/IDE cable. This information is present to both hard disk drive. This places a requirement to discriminate between the two drives. You must use the DRV bit in the drive/head (DH) register when issuing commands to the drives. +--------------+ Interface J5 +--------------+ |AT/IDE +------------+ +---+Jumper=MASTER | |HOST ADAPTER | | | |Master C: | | ++ +-----+ +--+---+DX-3120A | +--++----+ | | +--------------+ +--------------+ Power J1 | | |Power Supply +------------+--+ +--------------+ |+12 & +5 VDC +------------+------+Jumper=SLAVE | +--------------+ | |Slave D: | +------+DX-3120A | +--------------+ ********************************************************************** I N S T A L L ********************************************************************** DAEYOUNG DX-3120A 3.5 INCH DISK DRIVE PRODUCT MANUAL Notes on Installation ===================== Installation direction ---------------------- horizontally vertically +-----------------+ +--+ +--+ | | | +-----+ +-----+ | | | | | | | | | +-+-----------------+-+ | | | | | | +---------------------+ | | | | | | | | | | | | | | | | | | +---------------------+ | +-----+ +-----+ | +-+-----------------+-+ +--+ +--+ | | | | +-----------------+ Mounting -------- The drive may mount in any position. There are ten mounting holes provided in the drive chassis for installation. Ten of these holes accept 6-32 machine screws. Beadly warped or nonplanar mounting surfaces may distort the drive. Cabling ------- Up to two DX-3120A drives may be cabled to a single CPU/host adapter. They can be configured as master or slave. Power to the drives may be from a common power bus. The AT/IDE Task File intelligent drive interface may require a host adapter board. The host adapter allows installation of the drive in motherboards that do not an embedded AT/IDE interface. AT/IDE Cable Connections ------------------------ Cable connection between the host adapter or the host system should use 28 AWG stranded flat cable, or equivalent. The cable length should not exceed 2 feet. Drive and Host Adapter Installation ----------------------------------- Before installing the hard disk, you must first disconnect your AT computer system from AC power outlets. Remove the cover to the AT computer system. The DX-3120A needs six 6-32 screws to mount the drive. The drive mounts with the threaded holes on the bottom or sides. If needed, the AT-style side-mount rails attach to the Daeyoung 5.25" mounting brackets. Select screw length that limit screw penetration into the mounting brackets to 0.13 inches (3.3 mm) max. Notes In many new AT system cases 3.5" internal mounting options are available. Some AT case designs, need AT-style side-mount rails. Embedded AT/IDE systems don't need the PC/AT host adapters. Non-embedded AT/IDE systems need a host adapter. Host Adapter Configuration -------------------------- The PC/AT host adapters integrate AT compatible computer systems with AT/IDE interface hard disk drives. The host adapters require a 16-bit slot in the PC/AT or compatible system. The adapter board buffers the drive from the host and does the address decoding. The adapter board decodes the host I/O addresses 1F0 - 1F7 and 3F6 - 3F7. The disk drive uses these addresses in the AT BIOS. The floppy disk drive also responds to address 3F7, bit 7. The drive does not send bit 7. Most host adapters are not compatible with 8-bit bus XT computer systems. A host adapter can interface up to two AT/IDE hard disk drives. The host adapter also controls up to two floppy disk drives. Support of the floppy combinations must be in the system BIOS. The combinations are 3.5" (720 KB or 1.44 MB), or 5.25" (360 KB or 1.2 MB). There are two ways to support more than two floppy drives, on line in your system. You must use another floppy disk controller card with on- board BIOS, or a special software driver. Cabling and Hardware Installation --------------------------------- Unplug the system from AC outlets on the motherboard. Motherboards with an embedded AT/IDE interface cannot use a host adapter board. You must attach the 40-pin hard disk cable correctly to the 40-pin connector on the system motherboard. Pin 1 (red stripe) of the cable must match pin 1 of the 40-pin motherboard connector. Pin 1 of the disk drive (J5) connector must match pin 1 of the cable. Make sure that you insert a power connector from the computer system's power supply. Plug it into the power receptable at the rear of the DX-3120A disk drive. Hard Disk Systems needing a PC/AT host adapter ---------------------------------------------- Install the host adapter in any any available 16-bit slot in the computer system. Attach one end of the 40-pin hard disk drive cable to the 40-pin connector on the host adapter. Make sure pin 1 (red stripe) of the cable matches pin 1 of the 40-pin connector. Insert either of the two hard disk drive connectors at the other end of the 40-pin cable into the 40-pin connector on the PC board at the rear of the disk drive. Make sure pin 1 (red stripe) of the cable matches pin 1 of the 40-pin connector. The cable inserts only one way, see the cable key for the disk drive. Insert an available power connector from the computer system's power supply into the power receptable at the rear of the DX-3120A disk drive. For daisy-chain installations, make sure that both hard disk drives connect to the 40-pin cable. The physical placement of master of slave does not matter. Master or slave can attach to either available hard disk connector. The drive are selected by the master and slave jumpers on the jumper block. Be sure that both hard disk drives connected to available power connectors from the computer system's power supply. Floppy Drive Installation ------------------------- Attach the cable mount socket of the 34-pin floppy cable to the 34-pin connector on the host adapter. Make sure that pin 1 (red stripe) of the cable connector matches pin 1 of the host adapter 34- pin connector. Follow the floppy drive instructions for setting the terminating resistors and jumpers on the floppy drive. Floppy drive A attaches to the end of the cable with the twisted conductors. Floppy drive B attaches to the connector at the middle of the cable without the twist in the conductors. Plug the card edge cable connectors into the floppy drives. Decide the proper pin 1 orientations. Be sure that available power connectors from the computer system's power supply insert in the drive power receptacles. Other Connectors on the PC/AT host adapters ------------------------------------------- Most host adapters have a LED header to show hard disk drive activity. Connect the cable from the front panel LEDs of the computer system to the host adapter LED header. ********************************************************************** F E A T U R E S ********************************************************************** DAEYOUNG DX-3120A 3.5-INCH WINCHESTER DISK DRIVE PRODUCT MANUAL Introduction ------------ The DX-3120A Winchester disk drive is a storage device for a computer system with the industry standard PC/AT or AT/IDE interface. The DX- 3120A is a compact, lightweight, high capacity, and reliable disk drive. General Description ------------------- The DX-3120A has a formatted capacity of 120 MB. It uses a rotary band positioner driven by a bipolar stepper motor. The disk drive operates under the control of a microprocessor to position the read/ write heads. The head positioning mechanism design assures that the thermal loops of the positioning system oppose each other. This re- sults in extremely accurate head positioning over the entire operating range. The DX-3120A has a magnetic fluid seal. This eliminates spindle motor bearing contamination. The recirculation filter at the periphery of the disks efficiently cleans the head/disk assembly (HDA) air. The filter traps entrained particles. A single pronted circuit board (PCB) mounted beneath the HDA contains the electronics of the DX-3120A. The electronics accomplish the following functions: Provide on-board disgnostics Position the read/write heads Read and write data Interpret and generate control signals Maintain the correct spindle motor speed Seek Time --------- +----------------------------------+--------+ | |DX-3120A| +----------------------------------+--------+ |Track-to-Track msec. typ. | 2.04 | +----------------------------------+--------+ |Average msec. typ. | 19 | | msec. max. | 30.68 | +----------------------------------+--------+ |One-Third Stroke msec. max. | 17.86 | +----------------------------------+--------+ |Latency msec. avg. | 8.33 | +----------------------------------+--------+ Drive Formatting ---------------- The low level format is factory-writern. The DX-3120A drive uses cylinder/head skewing to improve data throughput performance. The format and skewing features of the drive are transparent to the user. Altering the Format during use is not possible. Drive Diagnostic ---------------- This command executes the internal diagnostic tests implemented by the drive. The diagnostic tests only execute upon the receipt of the command. Drive BSY sets immediately upon receipt of the command. If the drive is a mster with jumper block pin pair master jumpered, the drive performs the diagnostic tests and saves the results. Then it checks to see if a slave drive is present. The master then waits for 5 seconds for the slave to complete its diagnostics. If the slave completes the diagnostics successfully, it asserts -HOST PDIAG. If unsuccessful, it sets its error register as described below. Code |Error Description -----+--------------------------------- 01 |No error detected 02 |Formatter device code 03 |Sector buffer error 04 |ECC circuitry error 05 |Controlling Microprocessor error 8X |Slave drive failed Error Register -------------- This register contains status from the last command executed by the drive a Duagnostic Code. At the completion of any command except Execute Drive Diagnostic, the contents of this register are valid when ERR = 1 in the Status register.

UNC (Uncorrectable Data Error) indicates an uncorrectable data error has been encountered. IDNF (ID Not Found) indicates the requested sector's ID field could not be found. ABRT (Aborted Command) indicates the requested command has been aborted due to a drive status error or an invalid command. TK0NF (Track 0 Not Found) indicates "track 0 not found" during a Recalibrate command. AMNF (Address Mark Not Found) indicates the data address mark not found, after finding the correct ID field. 0 (Not used) These bits are 0.
