The drive operates within the specified error rates when tilted 5 degrees from these positions. Performance and error rate stay within specification limits even if the drive is operated in other orientations from which it was formatted. Thus a drive formatted in the horizontal orientation operates in the vertical position without any degradation, and vice versa. The recommended mounting screw torque is 3 0.5 [Kgf.cm]. The recommended mounting screw depth is 3.5 0.5 [mm] for bottom and 5.0 0.5 [mm] for horizontal mounting. The system is responsible for mounting the drive securely enough to prevent excessive motion or vibration of the drive at seek operation or spindle rotation, using appropriate screws or equivalent mounting hardware. The vibration test and the shock test ar eto be conducted with the drive mounted to the table using four bottom screws. Identification Labels --------------------- The following labels are affixed to every drive. 1. A label placed on the top of the HDA contains the statement "Made by IBM" or equivalent, Part number, and MLC number. 2. A bar code label placed on the disk drive is based on user request. The location is to be designated in the drawing. 3. Labels containing the vendor's name, disk drive model number, serial number, place of manufacture and UL/CSA logos. Except for the bar code, the labels may be integrated. The label portion will be changed in the next revision. Cabling ------- The maximum cable length from the host system to the drive, plus the circuit pattern length in the host system, cannot exceed 46 [cm]. Interface Connector ------------------- The DC 4-pin connector is designed to mate with AMP 1-480424-0 or equivalent. The AT signal connector is designed to mate with 3M 3417-7000 or equivalent. Interface Logic Signal Levels ----------------------------- The interface logic signal have the following electrical specifications: Inputs: Input High Voltage 2.0 V min. Input Low Voltage 0.8 V max. Outputs: Output High Voltage 2.4 V min. Output Low Voltage 0.5 V max. ********************************************************************** F E A T U R E S ********************************************************************** IBM DSAA-3XXX OEM FUNCTIONAL SPECIFICATIONS REV. 0.3, OCT. 1993 Products Outline ---------------- - Closed Loop actuator servo - Dedicated head landing zone - Automatic actuator look - 96 KB Sector Buffer (Option up to 224KB) - Read ahead of LRU cache algorithm - Write Cache - Enhanced ECC implementation - 128-bit Reed Solomon Code operating 10-bit symbol - Multi-burst On-The-Fly correction (up to 4 symbols in one sector) - Automatic Error Recovery Procedures for Read and Write - Self Diagnostics during Power On - PIO Data Transfer - Mode 2 - DMA Data Transfer - Single Word mode: mode 2 - Multiword mode: mode 1 (8.3 MB/sec) - CHS and LBA mode - Transparent defect management by Automatic Defect Reallocation during Write Cache - Power saving modes - MR (Magneto Resistive) Head technology Physical Format --------------- On manufacturing process, all sectors of hard disk drive are tested for the magnetical performance, so that only acceptable sectors are used. In data area, accepted sectors are numbered sequentially for user data sectors. This mapping information is maintained at firmware level, and data block addressed by logical cylinder, head and sector is translated into physical location on disk(s) automatically. This operation is invisible from application level. The hard disk drive never perform low-level format after manu- facturing process. Error Rate ---------- - Probability of not recovering data .... 1 in 10(13) bits read - ECC implementation 128-bit Non-interleave Reed Solomon Code operating 10-bit symbol is used to cover the data fields. On-The-Fly correction covers up to four symbols of error in one sector. Error Register -------------- +-----------------------------------+ | Error Register | +---+---+---+----+--+----+-----+----+ | 7 | 6 | 5 | 4 |3 | 2 | 1 | 0 | |BBK|UNC| 0 |IDNF|0 |ABRT|TK0NF|AMNF| +---+---+---+----+--+----+-----+----+ This register contains status from the last command executed by the drive, or a diagnostic code. At the completion of any command except Execute Drive Diagnostics, the contents of this register are valid. Following a power on, a reset, or completion of an Execute Drive Diagnostic command, this register contains a diagnostic code. Bit Definitions BBK Bad Block. BBK = 1 indicates a bad block mark was detected in the requested sector's ID field. UNC Uncorrectable Data Error. UNC = 1 indicates an uncorrectable data error has been encountered. IDNF(IDN) ID Not Found. IDN = 1 indicates the requested sector's ID field could not be found. ABRT(ABT) Aborted Command. ABT = 1 indicates the requested command has been aupported to a drive status error or an invalid parameter in an output register. TK0NF Track 0 Not Found. T0N = 1 indicates track 0 was not found (T0N) during a Recalibrate command. AMNF(AMN) Address Mark Not Found. AMN = 1 indicates the data address mark has not been found after finding the correct ID field for the requested sector. Read Look-Ahead --------------- The drive keeps the buffers into 32 Kbytes as read/write cache. - Least Frequent Used buffer is discareded to save the newly requested data. Write Cache ----------- When the write cache is enabled, write cache uses a dedicated 32 Kbytes buffer. (The write cache is enabled by checking jumper setting at power-on-reset period. And if the jumper setting is for enabling write cache, this can be enabled or disabled by sending set features commands.) - If the previous command is WRITE, and the block requested is consecutive to the previous, the drive will return "COMPLETE" after all data is received in the drive buffer. - Soft reset is recommended to check the actual data writing to media, i.e., soft reset is processed after the previous write command (with cache) completes the actual writing to media. - Certain power down during Write Cache operation may result in Non- recoverable error later. Write to the broken sector will recover this sector. - Automatic reallocation will be invoked at the failing sector if a non-recoverable error occurs and the write will be completed normally. - If the drive runs out of spares for reallocation, write cache and reallocation will be turned off. - If the drive is unable to complete a cached write and/or reallocation after good status has been returned, the drive will not process any commands including a soft reset. This condition will be cleared at power on, or a hardware reset. Warranty -------- The warranty will be covered by contracts. Landing Zone and Lock --------------------- A landing zone on the disk, not the data area of the disk, is provided to protect the disk data during shipping, movement, or storage. After power down, a head locking mechanism secures the heads in this zone. ********************************************************************** G E N E R A L ********************************************************************** IBM AT INSTALLATION (IDE-AT1) IDE Installation Guide Generic Installation requirements ------------------------- To install an IDE drive inside your computer, you must have: 1 The documentation that came with your computer. 2 The documentation that came with your hard drive. 3 A small, flat blade screwdriver. WARNING: Do not open the static-protective bag containing the drive until instructed to do so. Static electricity can damage the drive. Preparing the drive for installation ------------------------------------ Master drive If this drive is the first or primary hard disk drive to be installed inside your computer, check the manual that came with your hard drive to locate the Master setting. If your drive is set to a Master, do not change the jumper position. Slave drive If this drive is the second or secondary hard disk drive in your computer, you must change the jumper position on the drive to Slave. Refer to the manual that came with your hard disk drive to locate the Slave setting. To change the jumper on the hard disk drive: 1 Remove the drive from the static-protective bag and place it on top of the bag. 2 Refer to your manual and locate the pins. 3 If you need to change the setting, grasp the jumper and pull it off the pins. 4 Line up the two holes in the bottom of the jumper with the approprate two pins on the drive. Push the jumper onto the pins until the jumper is completely seated and covers both pins. Installing the drive -------------------- For the specific information on installing a hard disk drive, refer to the documentation that came with your computer. You will be required to mount the drive inside your computer, connect signal and power cables to the hard drive, and update the configuration information. Handling precautions -------------------- 01 Turn off all attached devices first; then turn off the computer. 02 Unplug all the power cords from electrical outlets before starting installation. 03 Disconnect all power cables from your computer and attached devices before starting installation. 04 Limit your movement. Movement can cause static electricity to build up around you. 05 Handle the drive carefully and by the edges. 06 Do not touch any exposed printed circuitry. 07 Prevent other people from touching the components or the drive. 08 When you are installing the drive, touch the static-protective package containing the drive to a metal expansion-slot screw or other unpainted metal surface on the computer, for at least 2 seconds. (This drains static electricity from the package and your body.) 09 When possible, remove the drive and install it directly into the computer without setting it down. If this is not possible, place the drive, component side up, on the static-protective bag on a flat surface until the drive is installed. 10 Do not place the drive on the computer cover or on a metal table. Note: Be sure to use the correct screws provided with your drive. Using the wrong ones might cause damage to the drive. Completing the installation procedure ------------------------------------- The installation of the drive is complete. Reinstall the cover on the computer or storage enclosure. Store these instructions and any extra parts in a safe place in case you change your configuration. After installing your hard disk drive, use the information that came with your computer to reconfigure your system. When you power on your system, turn on all attached devices first; then turn on the computer. If you have any problems at this point, turn off all attached devices; then, turn off the computer and check that: 1 The cables are installed correctly 2 No options or cables are loose 3 The jumpers are properly set Turn on all attached devices; then, turn on the computer. If you still have a problem, refer to the troubleshooting information in the documentation that came with your computer. Update configuration -------------------- Whenever you add or remove an option from your computer, you must update the configuration information. Your computer might have an automatic configuration program, or you might have to follow a specific procedure. For more information, refer to the documentation that came with your computer. Preparing the drive for use --------------------------- Having successfully installed the hard disk drive, you need to prepare it for use. Depending on the operating system you are using, you might need to partition then format the hard disk. Refer to the documentation that came with your operating system for information on how to format your new drive. To make the drive just installed your primary drive, you might need to create a new system partition on the drive. For information on creating a new system partition, refer to the documentation that came with your operating system. Troubleshooting --------------- You might be able to solve a problem yourself. Before calling IBM, you might want to try some or all of the following troubleshooting procedures. 1 Remove and reattach all drive cables 2 Remove and reseat the drive 3 Place the drive in a different slot, if one is available 4 If your drive contains jumpers or switches, check that they are set as specified 5 Reread any software instructions; be sure software settings are correct 6 Inspect the drive for damage, such as bent pins 7 Check the computer manual for instructions about the installation of upgrades. Look for a section about system setup or system configuration. Follow all procedures. 8 After completing these steps, reassemble the computer and connect the power cord If you are still having problems and want to call IBM technical support, have available as much of the following information as possible: 1 Drive model or P/N and description 2 Computer manufacturer and model 3 Exact wording of error message (if any) 4 Description of the problem 5 Hardware and software configuration information for your system If possible, be at your computer.
