SEAGATE  ST7050P  INSTALLATION MANUAL

 Notes On Installation
 =====================

 Drive handling and mounting
 ---------------------------
 The ST7050P, although shock-resistant, is susceptible to damage
 caused by rough handling, particularly when it is not mounted in
 a PCMCIA slot. Be careful not to drop the drive. Store the ST7050P
 in its protective case whenever it is not in use.


 Mounting the ST7050P
 ---------------------
 The ST7050P is designed to support the PCMCIA Type III standard for
 direct mounting. You can mount and operate the ST7050P in any
 orientation. To mount the drive, simply insert it into a Type III
 PCMCIA slot. You may have to power down your computer before
 changing PC Cards. See your computer manual for details.


 Software Installation Procedures
 ---------------------------------
 Before you can use the ST7050P on most computers, you must install
 the SystemSoft PCMCIA drivers using the SystemSoft installation.
 Then you must partition and format the PC Card.


 Generic installation procedure
 -------------------------------
 The following pages describe a general software installation
 procedure that you can use on most computers.

 1. Examine your Config.sys file. a. At the C:\ prompt, type type
 Config.sys. This displays the contents of your Config.sys file on
 the screen.
  b. If your Config.sys file contains:
  - a line that begins with device=emm386.exe or device=qemm386.exe,
    or
  - lines used to run previously installed PCMCIA drivers,
    then continue to step 2 below.

 2. Modify your Config.sys file (optional). a. Make a backup copy of
    your Config.sys file. At the C:\ prompt, type copy Config.sys
    config.old.
  b. If you are using a memory manager (such as EMM386), you may need
     to edit your Config.sys file to reserve memory space for the
     PCMCIA drivers at addresses D000 through DFFF. For example,
     if you have a line in your Config.sys file that reads
     device=emm386.exe, you must add the following text at the end
     of this line: noems x=d000-dfff.
  c. If your existing Config.sys file lists device drivers for a
     PCMCIA ATA card, you may have to remove the lines that refer to
     these drivers.
     See your computer manual or documentation for any previous
     PCMCIA drivers to determine which device drivers are loaded
     at startup.
  d. If you modified your Config.sys file, reboot your computer
     before running the SystemSoft installation program by pressing
     the CTRL, ALT and DELETE keys simultaneously.

 3.  Run the SystemSoft installation program.
  a. If you are running Microsoft Windows, you must exit Windows
     before running the installation program.
  b. Insert the SystemSoft installation diskette into your diskette
     drive.
  c. Type a:\install and press ENTER. If your diskette drive is drive
     B, type b:\install and press ENTER.
  d. At each stage of the installation, the program prompts you for
     input.
     Follow the instructions on each screen using the options listed
     below. Most of these options are preselected.
     - Select first-time installation.
     - Select standard (not custom) installation.
     - Select 1 or 2 PCMCIA sockets as appropriate.
       (See your computer manual.)
     - Select to have the software installed on drive C.
     - Select to have the software installed in a directory named
       \CARDSOFT.
     After you press ENTER to confirm the directory, the instal-
     lation program copies files from the diskette onto your
     internal hard drive.
     Then, it notifies you that it is about to modify your
     Config.sys file.
     When it modifies your Config.sys file, it adds PCMCIA drivers
     that are loaded into your computer each time you reboot. The
     installation program also makes a backup copy of your original
     Config.sys file. If you have an EMM386 memory manager, you will
     see a warning to exclude the D000 to DFFF memory addresses.
     This message appears even if you have already excluded these
     addresses during step 2 of the installation process.
     Press ENTER to continue the installation. Remove any PC Cards
     when requested to do so. Then, press ENTER. Eventually, you see
     the message Procedure is now complete. You are offered the choice
     of exiting to DOS or running Setup for Windows. Do not run Setup
     for Windows at this point in the installation. Instead, select
     Exit to DOS. At the end of the installation program, you see the
     prompt C:\CARDSOFT.

     NOTE.
     The installation program refers to several SystemSoft utility
     programs (CONFIG.EXE, CSALLOC and SETUP.EXE). For detailed
     descriptions of these programs, see the SystemSoft user
     documentation included with your ST7050P.
  e. After the installation program has finished, remove the instal-
     lation diskette from the drive. (The software does not prompt
     you to do this.)
     Then, reboot your computer by pressing the CTRL, ALT and DELETE
     keys simultaneously.
  f. After the computer has rebooted, insert the ST7050P into the
     PCMCIA slot. After you insert the ST7050P, you should hear two
     beeps (first low, then high) as the software recognizes and
     configures your PC Card.
     If you hear these two beeps, continue to instructions on
     partitioning and formatting the ST7050P.


 AST Bravo installation procedure
 =================================
 1. Check your system setup. Enter your computer's system setup
    program. Select the Security Setup menu and make sure that:
    - writing to the PC Card is enabled, and
    - booting from the PC Card is disabled.
    Then, press the ESC key twice to return to the DOS prompt.

 2. Modify your Config.sys file. Before running the SystemSoft
    installation software, you must edit your Config.sys file to
    disable previously installed PCMCIA drivers and to reserve
    memory space for the new PCMCIA drivers.
  a. Make a backup copy of your Config.sys file. At the C:\ prompt,
     type copy Config.sys config.old and press ENTER.
  b. Edit the Config.sys file and add the word rem at the beginning
     of the following lines (if present):
     device=c:\pcmcia\ssu.exe device=c:\pcmcia\ccu.exe /com=4
  c. If you are using a memory manager (such as EMM386), you must
     edit your Config.sys file to reserve memory space for the
     PCMCIA drivers at addresses D000 through DFFF. For example,
     if you have a line in your Config.sys file that begins with:
     device=emm386.exe, you must add the following text to the end
     of the line: noems x=d000-dfff.
  d. Save your new Config.sys program. Then, reboot your computer by
     pressing the CTRL, ALT and DELETE keys simultaneously.

 3. Run the SystemSoft installation program. a. If you are running
    Microsoft Windows, you must exit Windows before running the
    installation program.
  b. Insert the SystemSoft installation diskette into your diskette
     drive.
  c. Type a:\install and press ENTER.
  d. At each stage of the installation, the program prompts you for
     input. Follow the instructions on each screen using the options
     listed below.
     Most of these options are preselected.
     - Select first-time installation.
     - Select standard (not custom) installation.
     - Select 1 PCMCIA socket.
     - Select to have the software installed on drive C.
     - Select to have the software installed in a directory named
       \CARDSOFT.
     After you press ENTER to confirm the directory, the instal-
     lation program copies files from the diskette onto your
     internal hard drive. Then, it notifies you that it is about to
     modify your Config.sys file. When it modifies your Config.sys
     file, it adds PCMCIA drivers that are loaded into your computer
     each time you reboot. The installation program also makes a
     backup copy of your original CON-FIG.SYS file. If you have an
     EMM386 memory manager in your CON-FIG.SYS file, the program
     will suggest that you exclude the D000 to DFFF memory
     addresses. This message appears even if you have already
     excluded these addresses during step 2 of the installation
     process. Press ENTER to continue the installation. Remove any
     PC Cards when requested to do so. Then, press ENTER. Eventually,
     you see the message Procedure is now complete. You are offered
     the choice of exiting to DOS or running Setup for Windows. Do
     not run Setup for Windows at this point in the installation.
     Instead, select Exit to DOS. At the end of the installation
     program, you see the prompt C:\CARDSOFT.

     NOTE.
     The installation program refers to several SystemSoft utility
     programs (CONFIG.EXE, CSALLOC and SETUP.EXE). For detailed
     descriptions of these programs, see the SystemSoft user
     documentation included with your ST7050P.
  e. After the installation program has finished, remove the
     installation diskette from the drive. (The software does not
     prompt you to do this.)
     Continue to step 4 below.

 4. Modify your Config.sys file again. a. Edit the Config.sys file
    a second time. Look for the line that begins:
    device=c:\cardsoft\cs.exe. Add the text /irq=a to the end of
    this line. Save your new Config.sys file.
  b. Reboot your computer by pressing the CTRL, ALT and DELETE
     keys simultaneously.
  c. At the C: prompt, type cd\cardsoft and press ENTER.
  d. Type csalloc /g and press ENTER.
  e. Reboot your computer again. As the computer boots up, you may
     see the message Drive B assigned to PCMCIA socket 1. Despite
     this message, the AST Bravo accesses the ST7050P as drive D.

 5. Insert the ST7050P. Insert the ST7050P into the AST Bravo's
    PCMCIA slot. The card must be inserted upside down. After the
    computer has rebooted, insert the ST7050P into the PCMCIA slot.
    After you insert the ST7050P, you should hear two beeps (first
    low, then high) as the software recognizes and configures your
    PC Card. If you hear these two beeps, continue to instructions
    on partitioning and formatting the ST7050P.


 Compaq Concerto installation procedure
 =======================================
 Do not run the enclosed SystemSoft installation program on the
 Compaq Concerto. The Concerto's built-in PCMCIA software
 automatically recognizes and configures your ST7050P the first
 time you insert it. However, you must still partition and format
 the ST7050P before you can use it.
 1. Check Compaq PCMCIA drivers. From within Windows, open the
    Compaq Utilities group and start the Computer Setup program.
    Then, select the PCMCIA icon and click on the Options button.
    Make sure that the following boxes are checked:
    - Enable standard PCMCIA drivers
    - Enable PCMCIA ATA mass storage driver
    - Enable I/O card configuration driver
    For additional information, see your Compaq manual, beyond
    Install.
    When you are done checking the PCMCIA drivers, exit the Windows
    program.
 2. Insert the ST7050P. Insert the ST7050P into the PCMCIA slot.
    CAUTION! Be extremely careful when inserting the ST7050P into
    the Concerto's PCMCIA slot. If the screen is tilted away from
    you, you must insert the PC Card upside down (with the top of
    the PC Card toward the back of the screen). If you insert the
    card incorrectly or force it into the slot, you may bend your
    computer's PCMCIA connector pins.
    After you insert the ST7050P, you should hear two beeps as the
    software recognizes and configures the PC Card. If you hear
    these two beeps, continue to step 3 for instructions on
    partitioning the ST7050P. If you insert the card and hear a
    single low beep or no beep at all, see your Compaq manual.

 3. Partition the ST7050P. CAUTION! Repartitioning or reformatting the
    ST7050P destroys any data on the disc. Make sure that your back up
    all data before repartitioning or reformatting a PC Card. The
    ATACARD program does not warn you if the PC Card has previously
    been partitioned or contains data.
  a. Insert the ST7050P into the PCMCIA slot (listen for the two
     beeps that indicate the computer recognizes the card).
  b. Determine which drive letter has been assigned to the ST7050P
     (usually drive D). If in doubt, type cardinfo at the C:\
     prompt and press ENTER.
     CAUTION! If you partition the wrong drive, you will destroy
     data.
  c. Type c:\cpqdos\atacard.exe and press ENTER. Select the drive
     you want to partition.
  d. The program should display the following drive parameters on
     the screen:
     - Fixed Cylinders: 580 / Heads: 9 / Physical Sectors/track: 16
     If the parameters listed on your screen match those above,
     press ENTER to partition the disc. If the numbers do not match,
     reboot your computer and return to step a above.
     If given the option, do not use compact format. For more
     information, see your Compaq computer manual.

 4. Format the ST7050P. Format the ST7050P immediately after you
    partition it. Turn to formatting instructions.


 HP OmniBook 425 installation procedure
 =======================================
 1. Turn your computer on. 2. Insert the ST7050P in the PCMCIA slot.
    The first time you insert the ST7050P in your computer, the
    computer automatically configures itself to the drive. Then, it
    partitions and formats the drive.


 IBM ThinkPad 750 installation procedure
 ========================================
 1. Modify your Config.sys file. Before running the SystemSoft
    installation software, you must edit your Config.sys file to
    disable previously installed PCMCIA drivers and to reserve
    memory space for the new PCMCIA drivers.
  a. Make a backup copy of your Config.sys file. At the C:\ prompt,
     type copy Config.sys config.old and press ENTER.
  b. Edit the Config.sys file by typing e Config.sys and pressing
     ENTER.
     Add the letters rem at the beginning of the following lines (if
     present):
     DEVICE(high)=C:\THINKPAD\IBMDSS01.SYS /S0=2 DEVICEhigh=
     C:\THINKPAD\IBMDOSCS.SYS
  c. If you are using a memory manager (such as EMM386), you must
     edit your Config.sys file to reserve memory space for the
     PCMCIA drivers at addresses D000 through DFFF. For example, if
     you have a line in your Config.sys file that reads device=
     emm386.exe, you must add the following text at the end of the
     line: noems x=d000-dfff.
  d. Save your new Config.sys program, then reboot your computer by
     pressing the CTRL, ALT and DELETE keys simultaneously.

 2. Run the SystemSoft installation program. a. If you are running MS
    Windows, you must exit Win-dows before running the installation
    program.
  b. Insert the SystemSoft installation diskette into your floppy
     drive.
  c. Type a:\install and press ENTER.IBMd. At each stage of the
     installation, the program prompts you for input. Follow the
     instructions on each screen using the options listed below.
     Most of these options are preselected.
     - Select first-time installation.

     - Select 2 PCMCIA sockets.
     - Select to have the software installed on drive C.
     - Select to have the software installed in a directory named
       \CARDSOFT.
     After you press ENTER to confirm the directory, the installation
     program copies files from the diskette onto your internal hard
     drive. Then, it notifies you that it is about to modify your
     Config.sys file. When it modifies your Config.sys file, it adds
     PCMCIA drivers that are loaded into your computer each time you
     reboot. The installation program also makes a backup copy of
     your original Config.sys file. If you have an EMM386 memory
     manager in your Config.sys file, the program will suggest that
     you exclude the D000 to DFFF memory addresses.
     This message appears even if you have already excluded these
     addresses during step 2 of the installation process. Press
     ENTER to continue the installation. Remove any PC Cards when
     requested to do so. Then, press ENTER. Eventually, you see the
     message Procedure is now complete. You are offered the choice of
     exiting to DOS or running Setup for Windows. Do not run Setup
     for Windows at this point in the installation.
     Instead, select Exit to DOS. At the end of the installation
     program, you see the prompt C:\CARDSOFT.

     NOTE.
     The installation program refers to several SystemSoft utility

 3. Modify your Config.sys file (optional). a. Make a backup copy of
    your Config.sys file. At the C:\ prompt, type copy Config.sys
    config.old and press ENTER.
  b. If you are using a memory manager (such as EMM386), you must
     edit your Config.sys file to reserve memory space for the
     PCMCIA drivers at addresses D000 through DFFF. For example,
     if you have a line in your Config.sys file that reads device=
     emm386.exe, you must add the following text at the end of the
     line: noems x=d000-dfff.
  c. If you have previously installed PCMCIA driver software, you
     must edit your Config.sys file and remove any existing PCMCIA
     device drivers before running the Sys-temSoft installation
     program.
     See the documentation that came with your previous PCMCIA
     driver for a list of drivers listed in the Config.sys file.
  d. If you modified your Config.sys file, reboot your computer
     before running the SystemSoft installation program by pressing
     the CTRL, ALT and DELETE keys simultaneously.

 4. Run the SystemSoft installation program a. If you are running MS
    Windows, you must exit Windows before running the installation
    program.
  b. Insert the SystemSoft installation diskette into your floppy
     drive.
  c. Type a:\install and press ENTER.
  d. At each stage of the installation, the program prompts you for
     input. Follow the instructions on each screen using the options
     listed below. Most of these options are preselected.
     - Select first-time installation.
     - Select standard (not custom) installation.
     - Select 1 PCMCIA socket.
     - Select to have the software installed on drive C.
     - Select to have the software installed in a directory named
       \CARDSOFT.
     After you press ENTER to confirm the directory, the installation
     program copies files from the diskette onto your internal hard
     drive. Then, it notifies you that it is about to modify your
     Config.sys file. When it modifies your Config.sys file, it adds
     PCMCIA drivers that are loaded into your computer each time you
     reboot. The installation program also makes a backup copy of
     your original Config.sys file. If you have an EMM386 memory
     manager in your Config.sys file, the program will suggest
     that you exclude the D000 to DFFF memory addresses. This
     message appears even if you have already excluded these
     addresses during step 2 of the installation process. Press
     ENTER to continue the installation. Remove any PC Cards when
     requested to do so. Then, press ENTER. Eventually, you see the
     message Procedure is now complete. You are offered the choice
     of exiting to DOS or running Setup for WIN.
     Do not run Setup for Windows at this point in the installation.
     Instead, select Exit to DOS. At the end of the installation
     program, you see the prompt C:\CARDSOFT.
     NOTE. The installation program refers to several SystemSoft
     utility programs (CONFIG.EXE, CSALLOC and SETUP.EXE). For
     detailed descriptions of these programs, see the SystemSoft
     user documentation included with your ST7050P.
  e. Just before it completes the installation, the program tells
     you to reboot your computer. First, remove the installation
     diskette from the drive. (The software does not prompt you to
     do this.) Then, turn your computer off.TInsert the ST7050P.
     Then, turn your computer on.
     While the computer is booting up, you should hear two beeps
     (first low, then high) as the software recognizes and con-
     figures your PC Card. If you hear these two beeps, continue
     to instructions on partitioning and formatting the ST7050P.

SEAGATE  ST7050P  INSTALLATION MANUAL


 Seek time
 ---------
 Seek time is defined as the interval between the time the actuator
 begins to move and the time the head has settled over the target
 track.
 Seek times shown here do not include controller or host overhead.
 All measurements are taken at 5.0V at sea level and 25*C ambient
 temperature. Track-to-track seek time is an average of all possible
 single-track seeks in both directions. Average seek time is measured
 by executing seek commands between random target tracks. Full-stroke
 seek time is one-half the time required for the drive to seek from
 track 0 to the highest-numbered track and back to track zero.

 Track-to-track read (msec) write (msec) 6/7
 Average read (msec) write (msec) 18/20
 Full-stroke read (msec) write (msec)<28/<30
 Average latency (msec) 8.46


 Spinup times
 ------------
 Power-on to Ready (sec) 5 (typical)
 Standby to Ready (sec) 2 (max)


 Power-management mode descriptions
 ----------------------------------
 The ST7050P features four power-management modes: Active, Idle,
 Standby and Sleep. These modes are available to the drive in either
 PC Card ATA and in 68-pin ATA mode.

 Active mode
 -----------
 In Active mode, the drive performs all normal disc activities,
 including reads, writes and seeks.

 Idle mode
 ---------
 In Idle mode, the spindle remains up to speed, but the heads are
 parked away from the data zones for maximum data safety. The buffer
 remains enabled, and the drive accepts all commands. From Idle mode,
 the drive enters Active mode whenever disc access is necessary. At
 power-on, the drive sets the idle timer to 5 seconds (the drive
 enters Idle mode after 5 seconds of inactivity). In some computers,
 you can manually set the idle timer using the system setup utility.


 Standby mode
 ------------
 In Standby mode, the buffer remains enabled, the heads are parked and
 the spindle is at rest. The drive accepts all commands and returns to
 Active mode whenever disc access is necessary. The drive enters
 Standby mode when the host sends a Standby Immediate command. If the
 host system has set the standby timer, the drive can also enter
 Standby mode automatically after the drive has been in Idle mode for
 a specifiable length of time. The standby timer delay is
 system-dependent and is usually set using the system setup utility.


 Sleep mode
 ----------
 In sleep mode, the drive heads are parked and the spindle is at rest.
 The drive enters Sleep mode when a Sleep Immediate command has been
 received from the host. The drive leaves Sleep mode when the host
 sends a Hard Reset or Soft Reset command. After the drive receives a
 soft reset, it exits Sleep mode with all current emulation and
 translation parameters intact.


 Idle and standby timers
 -----------------------
 At power-on, the drive sets the default time delay for the idle timer
 to five seconds. In most systems, you can manually set this delay
 using the system setup utility. Each time the drive performs an
 Active function (read, write or seek), the idle timer is
 reinitialized and begins the countdown from the specified delay time
 to zero. If the idle timer reaches zero before any drive activity is
 required, the drive enters Idle mode. If the host has set the standby
 timer, the drive begins the standby timer countdown as soon as it
 enters Idle mode. If the host has not set the standby timer, the
 drive remains in Idle mode. If the standby timer reaches zero before
 any drive activity is required, the drive enters Standby mode. In
 both Idle and Standby modes, the drive accepts all commands and
 returns to Active mode when disc access is necessary.


 Power consumption
 -----------------
 Typical power measurements are based on an average of drives tested
 under nominal conditions using 5.0V input voltage at 25*C ambient
 temperature at sea level. Active mode power is measured with two
 spindle rotations between each operation and the drive in default
 logical geometry. Seek power is measured during one-third-stroke
 buffered seeks. Read/write power is measured with the heads on track.

 Typical startup currents for the ST7050P are 0.45 amps (0.50 amps
 maximum).
 Transient state changes may cause current peaks above the maximum
 level.


 PC Card ATA/68-pin ATA interface
 --------------------------------
 The ST7050P supports the industry-standard ATA specification
 task-file interface and the PC Card ATA interface specification
 (Version 2.1).

 Pin 9 is used to select either 68-pin ATA or PC Card ATA mode. If the
 OE- signal is low during power-on reset, then the ST7050P configures
 itself as a 68-pin ATA drive. If the OE- signal goes high within the
 first 100 msec after power-on, the ST7050P configures itself as a PC
 Card ATA drive. If the OE- signal ever goes high after the first 100
 msec following power-on, the drive enters an undefined state.

 NOTE.
 To operate the drive only in 68-pin ATA mode, pin 9 of the host
 interface should be permanently connected to a DC ground.


 Features of the PC Card ATA interface
 --------------------------------------
 For a detailed description of the PC Card ATA interface, see the PC
 Card ATA Specification, available from: PCMCIA 1030G East Duane
 Avenue Sunnyvale, CA 94086 Phone: (408) 720-0107. The ST7050P
 supports all standard PC Card ATA registers and bits except the
 audio, power-down, write protect, and battery voltage detection bits.
 The ST7050P does not currently support twin-card addressing.


 System compatibility
 --------------------
 A large number of new PCMCIA host systems are currently entering the
 marketplace along with various implementations of the PC Card ATA
 interface. For a complete listing of systems that have been tested
 for compatibility with the ST7050P, contact Seagate technical
 support.


 Features of the 68-pin ATA interface
 ------------------------------------
 In general, the 68-pin ATA interface for the ST7050P uses the same
 basic ATA signals as Seagate's 3.5-inch and 1.8-inch AT drives. These
 signals are simply mapped to different pins. A detailed description
 of Seagate's implementation of the ATA interface is presented in the
 Seagate ATA Interface Reference Manual. Elements of the ATA interface
 that are unique to the ST7050P are summarized in the following
 sections of this manual. In 68-pin ATA mode, the drive supports both
 8-bit and 16-bit data transfer and has no DMA capability. All data
 transfers are completed through programmed I/O. The ST7050P does not
 currently support master-slave handshaking.


 Remote LED
 ----------
 The drive indicates activity to the host through the DASP- line on
 the ATA interface. This line can be connected to a drive status
 indicator driving an LED.


 ATA bus signal levels
 ---------------------
 Signals sent by the drive have the following output characteristics
 at the drive connector:

 Logic Low 0 to 0.4V Logic High 2.5 to 5.25V

 Signals received by the drive must have the following input charac-
 teristics, measured at the drive connector:

 Logic Low 0 to 0.8V Logic High 2.0 to 5.25V


 System compatibility
 --------------------
 The ST7050P and SystemSoft PCMCIA drivers have been tested with DOS
 and Microsoft Windows on many computers, including those listed on
 the enclosed system compatibility sheet. For compatibility with the
 ST7050P, your computer must meet the requirements listed below. If in
 doubt, look in your computer manual.

 Your computer must have: - One Type III PCMCIA slot (10.5 mm high),
 or
 Two Type II PCMCIA slots (each 5 mm high) configured to accept a
 Type III PC Card.
 Your PCMCIA slot must be designed for a 5-volt PCMCIA device.
 Your computer must support a PC Card with a peak starting current of
 at least 0.5 amps.
 Your computer must support Version 2.0 or later of the PC Card
 Standard specification.

 NOTE.
 The ST7050P is a dual-interface card and can be used with a PC Card
 ATA interface or a 68-pin ATA interface. At startup the ST7050P
 automatically detects which interface is being used and configures
 itself appropriately.

 This User's Guide describes the installation and use of the ST7050P
 with a PC Card ATA interface only.


 Partitioning and formatting the ST7050P
 ----------------------------------------
 CAUTION!
 Repartitioning or reformatting the ST7050P destroys all data on the
 disc.
 Make sure the you back up all data before repartitioning or
 reformatting the card. The ATAINIT pro-gram does not warn you if the
 PC Card has previously been partitioned or contains data.


 Partitioning the ST7050P
 ------------------------
 1. Insert the ST7050P into the PCMCIA slot. Listen for the two beeps
    that indicate the computer recognizes the card.
 2. Determine which drive letter has been assigned to the ST7050P
    (usually drive D). If in doubt, type: c:\card-soft\ cardinfo
    and press ENTER.
    CAUTION!
    Make sure that you select the correct drive. You will destroy all
    data on the drive you select.
 3. Type c:\cardsoft\atainit and press ENTER. Then, select the drive
    to partition.
 4. The program should display the following drive parameters on the
    screen:
    Fixed Cylinders: 580 Heads: 9 Physical Sectors/Track: 16
    If the parameters listed on your screen match those above, press
    ENTER to partition the disc. If the numbers do not match,
    restart your computer, insert the ST7050P, and run the ATAINIT
    program again.
    If given the option, do not select compact format.
 5. Format the ST7050P immediately after you partition it.


 Formatting the ST7050P
 -----------------------
 1. Make sure the PC Card is inserted in the PCMCIA slot.
 2. Determine which drive letter is used by the card (usually drive
    D).
    If in doubt, type: c:\cardsoft\cardinfo and press ENTER.
 3. At the C:\ prompt, type format d: /u (assuming that the card is
    drive D). The FORMAT program then prompts you to enter a drive
    volume label. Type any name you want (up to 11 characters in
    length).
 4. To make sure the PC Card is working and to see a display of
    available space on the card, type chkdsk d: and press ENTER.
    The output should show at least 40 Mbytes of free space.


 Inserting the ST7050P
 ---------------------
 Make sure that no other cards or protective devices are in the PCMCIA
 slot. Gently slide the ST7050P into the slot until it meets
 resistance. Then gently push on it to make sure the pins are fully
 engaged. The card should slide in easily. If you force the ST7050P
 into the slot, you may damage the pins. In some computers, you must
 insert the card upside down. If you are using the SystemSoft PCMCIA
 driver supplied with the ST7050P, your computer indicates that it
 recognizes a PC Card by emitting two beeps, the first beep lower than
 the second. If the computer recognizes but cannot configure the PC
 Card, it emits a single low beep. No beep indicates either that the
 PC Card has not been inserted completely or that it has not been
 recognized.

 When you insert the ST7050P into a slot, the drive motor takes about
 three to five seconds to come up to speed. If you try to access the
 PC Card while the motor is spinning up, you may see a message,
 General failure reading drive D. Abort? Retry? Fail?. If this occurs,
 simply wait a few seconds, then press R to retry.


 Hot Plugging
 -------------
 Many computers allow you to insert or remove a PC Card while the
 computer is in normal operation (hot plugging). However, some
 computers must be turned off before you can remove or insert a PC
 Card, or rebooted after PC Cards are changed.
 CAUTION!
 If your computer does not support hot plugging, removing the PC Card
 while the computer is in operation may cause you to lose data.
 In addition, while in Standby or Sleep mode, your computer may not
 recognize that a PCMCIA card has been inserted or removed. Read your
 computer manual carefully to determine under what conditions you can
 insert or remove a PCMCIA device.


 Removing the ST7050P
 ---------------------
 Before removing the ST7050P, make sure all data has been saved. If
 your computer has an eject button or slide, gently push the button or
 slide. Then, slowly pull the card outward. Do not bump or drop the
 ST7050P as you are removing it from the slot. If you are using the
 SystemSoft PCMCIA driver, your computer should emit two beeps -the
 first beep higher than the second- when you remove the PC Card.

 If you have difficulty removing the PC Card, make sure that it is not
 locked in the slot. See your computer manual for details.
 CAUTION! The eject mechanism on some computers is strong enough that
 an ejected PC Card may slide completely out of its slot. This could
 damage the ST7050P if it falls out onto a hard surface. Before
 ejecting the ST7050P, always place your hand next to the slot to
 catch the card as it comes out.


 Saving safely
 --------------
 Do not remove the ST7050P or turn the computer off while information
 is being transferred (for example, immediately after loading or
 saving a file). Wait a few seconds after saving your work to ensure
 that all disc operations have been completed. If you remove the
 ST7050P before all data has been saved, you will lose data. Some
 computers automatically stop disc activity when they enter Standby
 mode or Sleep mode or when their covers are closed. If your computer
 has this feature, be sure that all data has been saved before you
 close the cover.

 If your computer uses write caching, data that has apparently been
 saved may be transferred to the cache and stored there for a while
 before being transferred to the ST7050P. If you remove or power down
 the ST7050P before it has received this data from the cache, you will
 lose the data. For this reason, we recommend that you do not use
 write caching with the ST7050P.


 General information
 --------------------
 After you partition and format your ST7050P, DOS or Windows can
 access the PC Card as drive D or E. If you remove the card and try to
 access information on it, you will see a Device not ready message.
