The Caviar hard drive is an intelligent drive, which means that the hard disk has the controller circuitry and 40-pin connector attached directly to the drive and doesn't require a slot-mounted controller card. Because of its compact size (1-inch height), the Caviar drive is easily incorporated into the newest generation of small desktop and transportable PC/AT systems. The Caviar hard disk is a 3 1/2" drive that can also be used in a 5 1/4" drive bay with a drive frame available from your distributor. With an average seek time of less than 18 msec, and a 1:1 interleave, the Caviar operates in high speed, AT compatible systems such as 80386SX, 80386, and 80486-based computers. YOUR INTELLIGENT DRIVE IS PREFORMATTED (LOW-LEVEL), AND DEFECT FREE. You can use your Caviar drive with Disk Operating System (DOS) version 3.0 or later. It is also compatible with other operating systems such as OS/2(TM), Xenix(TM), and Novell Netware(TM). The Caviar contains an automatic disk head parking feature that parks the disk drive heads in a safe, non-data area when the system power is turned off. This allows you to move the computer system without damaging the hard disk media. For more technical information and specifications on the Caviar intelligent disk drive, refer to the Reference chapter. =========================================================================== INSTALLATION OPTIONS =========================================================================== There are a number of installation options depending on your current system components and configuration. o If your system has a 40-pin connector on the motherboard, the Caviar drive is cabled directly to the motherboard. o If your system does not have a 40-pin connector on the motherboard, you need to install an adaptor card and connect the hard drive to the connector on the adaptor card. o If you are installing the Caviar drive as your second hard drive (dual installation), the hard drives need to be daisy-chained together using a daisy-chain cable. One connector attaches to the adapter card or motherboard, and the other two attach to the drives. If you need to install an adapter card, your floppy drive(s) can also be connected to an adapter card with floppy support, such as the WDAT240. This allows you to remove the floppy controller card from your system to create space for other cards you may want to add. The Caviar drive is not compatible with non-intelligent drives such as the ST-506 hard drive using a standard AT controller. If you have an ST-506 drive, you need to remove the hard drive and controller card before installing the Caviar drive. You need an adapter card in this installation unless the motherboard has a 40-pin connector. If you have an original IBM PC/AT with a Conner CP342 or CP3022 disk drive installed, you cannot add a second drive. Therefore, the Caviar drive will not work in this environment. If you have a PC/AT that is not manufactured by IBM with a Conner CP342 or CP3022 disk drive, you can add the Caviar as a second drive. You must configure the Conner drive as the master, and the Caviar as the slave. =========================================================================== UNPACKING =========================================================================== Western Digital products are designed to withstand normal handling when unpacking and installing the drive. Be aware of the following precautions when unpacking and installing the Caviar drive. =========================================================================== PRECAUTIONS =========================================================================== o Be careful when handling the disk drive. Do not drop, discharge static electricity, or cause shock to the drive components. Doing so can permanently damage the drive and void the warranty. o Handle the intelligent drive by the ends to avoid touching the circuit board components. o Do not lift the intelligent drive by the faceplate or the circuit board. o Once the Caviar drive is unpacked, only place the drive on anti-static surfaces, such as the antistatic drive bag. We recommend that you do not unpack the drive until you are ready to install it. =========================================================================== BEFORE INSTALLING THE DRIVE =========================================================================== ** CAUTION ** Remember to handle the drive with care. Leave the drive in the anti- static bag until you are ready to install it into your system. This protects the components from damage and static. Remember to handle the drive by the edges to avoid contact with the circuit components. ******* Be sure that you have the following items before installing your new Caviar drive: o Computer system manual. o DOS version 3.0 or later, or compatible operating system. o Operating system manual. o A Phillips head screwdriver. o A 40-pin host interface cable, not more than 18 inches long. There are some other items your system may require: o You may need to use a power Y-adapter if you are installing the Caviar drive as a second hard drive and you do not have two internal power connectors. This adapter can be purchased through your computer supplier. o Some systems require manufacturer-supplied drive mounting rails. Check your computer system manual to determine if drive mounting rails are required. These rails can be purchased through your computer manufacturer or supplier. o If you are installing the Caviar intelligent disk in a 5 1/4" drive bay, you need a 5 1/4" frame, which mounts on the Caviar disk drive. This frame is manufactured by Western Digital and can be purchased through your distributor as a 5.25 Kit or 5.25 Kit + Cable. o If your system does not have a 40-pin connector on the motherboard, you need an adapter card to connect the drive. Usually, replacing an ST-506 drive requires the use of an adapter card. =========================================================================== WESTERN DIGITAL DRIVE CONFIGURATION KITS =========================================================================== The following Western Digital kits are available for the Caviar drive from your distributor: o WD 5.25 Kit The 5.25 Kit contains one 5 1/4" frame, two faceplates with LEDs, four large screws for the drive frame, two small screws for the faceplate, and one male-to-male adapter for connecting the LED cable to the Caviar drive. o WD 5.25 Kit + Cable The 5.25 Kit + Cable contains an 18", 40-pin interface cable as well as all the contents listed in the 5.25 Kit. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ INSTALLATION ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ =========================================================================== OVERVIEW =========================================================================== This section provides the steps necessary to prepare and install the Caviar intelligent disk drive in your computer. o STEP ONE: Determining Your Installation Configuration o STEP TWO: Setting The Drive Jumpers o STEP THREE: Installing The 5 1/4" Faceplate And Frame (if you are installing Caviar in a 5 1/4" drive bay.) o STEP FOUR: Mounting The Drive o STEP FIVE: Installing The Adapter Card =========================================================================== STEP ONE: DETERMINING YOUR INSTALLATION CONFIGURATION =========================================================================== Once you have all of the items necessary, you are ready to install the intelligent drive in your system. You may use the Caviar drive as a new disk in the computer, or as a replacement for an existing hard disk drive. There are two main installation configurations: o The drive is cabled directly to a 40-pin connector on the motherboard. o The drive is cabled to an adapter card mounted in one of the expansion card slots in the computer. Both configurations use a 40-pin host interface cable. If you are using the Caviar drive as one of two hard disk drives in the computer (dual installation), you may use either configuration. In dual installations, you must use a 40-pin host interface cable with three connectors, and daisy-chain the two drives to the motherboard or adapter card. Western Digital provides three adapter cards for use with the Caviar drive. o The WDAT-140 adapter card supports two intelligent drives. o The WDAT-240 supports two intelligent drives and two floppy drives. o The WDAT-440 supports two intelligent drives, two floppy drives, two serial ports, and one parallel port. This manual describes and provides information on the most commonly used adapter card, the WDAT-240. If you prefer to use either the WDAT-140 or WDAT-440, contact your Western Digital distributor for related documentation on the adapter cards (part number WDATHAIG). --------------------------------------------------------------------------- DUAL INSTALLATIONS --------------------------------------------------------------------------- Dual installations require a master/slave drive configuration, where one drive is designated as the primary drive and the other is designated as the secondary drive. The Caviar drive is compatible in dual installations with other intelligent drives that support a master/slave configuration. The Caviar drive is not compatible with ST-506 drives. If your system contains an ST-506 drive, you must remove the drive and controller card before installing the Caviar drive. Most ST-506 replacements require the use of a Western Digital adapter. If you have an original IBM PC/AT with a Conner CP342 or CP3022 drive, you cannot install the Caviar drive. The Conner must be configured as the master drive if you are using the adapter card. If you have a PC/AT compatible computer not manufactured by IBM with a Conner drive, you can install the Caviar as the slave in this dual installation. If your installation requires the use of an adapter card, it is useful to know that you may also be able to connect your floppy drive(s) to the adapter card. You may need to connect a floppy drive to the adapter card in order to use the floppy drive if all the card slots are in use, or you may choose to connect the floppy drive(s) to the adapter card to leave space available for additional cards in the future. If you use the WDAT- 240 adapter card, you may connect two floppy drives to the adapter card. Be sure to determine your installation requirements, configuration, and materials before proceeding. =========================================================================== STEP TWO: SETTING THE DRIVE JUMPERS =========================================================================== The Caviar drive has a jumper block (J8) located next to the 40-pin connector on the drive. These jumpers define information about the hard drive. The Caviar drive is initially set for single drive installation. If you are installing the Caviar drive as the only intelligent drive in your system, you do not need to install the jumpers. This is considered a standard installation, and no jumpers are required. If you need to change this configuration, contact your distributor for jumper shunts, small plastic brackets that fit over two jumper pins. Using jumper shunts you can designate which drive in a dual installation is the primary (master) drive, and which drive is the secondary (slave) drive. o If you have a dual installation (two intelligent drives) you must designate one of the drives as the master and the other as the slave drive. The jumper pins on jumper J8 need to be configured for the dual installation. - To designate the intelligent drive as the master, place a jumper shunt on pins 5-6. - To designate the intelligent drive as the slave, place a jumper shunt on pins 3-4. o If your system is a PC/AT compatible computer not manufactured by IBM, and it contains a Conner CP342 or CP3022 drive, you can install the Caviar drive as a second drive. In this configuration, the Conner drive must be configured as the master, and the Caviar as the slave. To designate the Caviar drive as the slave to the Conner drive, place jumper shunts on pins 1-2 and 3-4. Refer to the Conner manual to configure the Conner drive as the master. o If your system is an IBM PC/AT with a Conner CP342 or CP3022 drive, you cannot install the Caviar drive as a second drive. To install a jumper shunt on the J8 jumper pins: 1. Refer to the previous descriptions and Figure 1 to determine your configuration. 2. Using one of the jumper shunts, place the shunt over the two pins specified in Figure 1. 3. Push the shunt into place until it is flush against the base of the jumper block.

The LED and faceplate are installed at the factory. If you are installing the Caviar drive in a 5 1/4" drive bay however, you need to perform these four procedures: o Remove the factory faceplate and LED o Attach the faceplate to the frame o Install the LED o Attach the frame to the drive For installation in a 5 1/4" drive bay, you must have the optional hardware in the WD 5.25 Kit or the WD 5.25 Kit + Cable. --------------------------------------------------------------------------- REMOVING THE FACTORY FACEPLATE AND LED --------------------------------------------------------------------------- 1. Place the disk drive circuit board side down on an antistatic surface, such as the antistatic bag. 2. Pull the bottom edge of the faceplate away from the drive until it is free. Then lift the faceplate straight up to free the hook on the top surface of the drive. 3. Grasp the LED firmly with small pliers or tweezers and pull it straight out. --------------------------------------------------------------------------- ATTACHING THE 5 1/4" FACEPLATE TO THE 5 1/4" FRAME --------------------------------------------------------------------------- 1. Place the 5 1/4" frame from the 5.25 Kit on a flat surface, such as a table. Place the open end of the frame away from you. The square cut- out on the frame for the LED cable should be on the left facing toward you. 2. Select either the black or gray faceplate from the 5.25 Kit. 3. Move the frame to the edge of the table and route the white LED cable on the faceplate through the square opening on the frame. 4. Insert the plastic tabs of the faceplate through the square holes on the front of the frame. Place the faceplate flush on the frame. 5. Align the screw holes on the faceplate with the screw holes on the frame. 6. Use a screwdriver and the two small screws from the 5.25 Kit to attach the faceplate to the frame. --------------------------------------------------------------------------- INSTALLING THE 5 1/4" LED --------------------------------------------------------------------------- 1. Remove the two-pin adapter from the small plastic bag of the 5.25 Kit. The two-pin adapter is the small, four-prong connector. 2. Connect the long prongs of the two-pin adapter to the LED cable connector. 3. Locate the J4 connector on the circuit board side of the Caviar drive. This is the connector that held the factory-installed LED. 4. Turn the drive over so that the drive LED connector is aligned with the square opening of the frame. 5. Insert the small prongs of the faceplate LED into the drive LED connector so that the P7 label on the LED cable connector is facing down. 6. Be sure that the LED cable connector is firmly seated in the drive LED connector. NOTE: Be careful while handling the drive. Do not drop or shock the drive, or touch the circuit board components. --------------------------------------------------------------------------- ATTACHING THE 5 1/4" FRAME TO THE DRIVE --------------------------------------------------------------------------- 1. Locate the screw locations on the frame for the Caviar drive by looking at the inside of the frame. 2. Place the frame around the drive so that the 40-pin connector end of the drive is at the open end of the frame. 3. With the frame around the drive, turn the frame on its side. 4. Align the two drive screw locations with the two frame screw locations by looking through the holes on the outside of the frame. 5. Attach the frame to the drive using a screwdriver and two of the remaining four screws from the 5.25 Kit. 6. Turn the frame over onto its other side and completely attach the frame to the drive by inserting the remaining two screws. Secure them in place using the screwdriver. Once the faceplate and frame are installed, you are ready to mount the Caviar drive in the 5 1/4" drive bay. =========================================================================== STEP FOUR: MOUNTING THE DRIVE =========================================================================== ** WARNING ** You may damage the Caviar drive if the interface cable is not connected properly. To prevent incorrect connection, use a cable that has keyed connectors. The female connectors on the interface cable should have plugs in position 20. ******* If you are replacing an existing hard drive with the Caviar drive, or if you currently have an ST-506 drive, you need to remove the existing drive and controller card. For instructions on removing your existing drive, refer to your system manual. You are now ready to install the Caviar drive. Make sure your interface cable is no longer than 18 inches. Also, if you are connecting two drives together, you need a daisy-chain cable that has three, 40-pin connectors. You may order this cable from your distributor. --------------------------------------------------------------------------- CONNECT THE INTERFACE CABLE TO THE DRIVE --------------------------------------------------------------------------- 1. Connect the 40-pin interface cable to the 40-pin connector on the Caviar hard drive. For dual installations, daisy-chain the two drives together by connecting them with a three-connector interface cable. 2. Route the cable toward the motherboard or card slot area. The cable should easily route from the hard drive to the card slot area. The cable should not block air flow paths. 3. Insert the drive halfway into the drive bay. --------------------------------------------------------------------------- CONNECT THE POWER SUPPLY CABLE --------------------------------------------------------------------------- 1. Attach the power cable to the power connector on the hard drive. 2. Attach the other end of the power cable to the power supply in your computer. 3. Completely insert the drive into your system drive bay. --------------------------------------------------------------------------- INSERT MOUNTING SCREWS --------------------------------------------------------------------------- 1. Mount the Caviar drive and frame to the drive bay using four 6-32 screws (3/16"). Be sure to use the correct size screws. Do not install the screws past six threads. Screws that are too long will damage the Caviar drive. --------------------------------------------------------------------------- CONNECT THE INTERFACE CABLE TO THE HOST --------------------------------------------------------------------------- 1. If you have a 40-pin connector on the motherboard, connect the other end of the interface cable to the motherboard connector. 2. If your installation requires an adapter card, as explained in STEP ONE, install the adapter card as described in the next section. 3. If you do not need to install the adapter card, close the computer case according to the instructions provided in your system manual and proceed to PREPARING THE CAVIAR DRIVE FOR USE. =========================================================================== STEP FIVE: INSTALLING THE ADAPTER CARD =========================================================================== NOTE: You only need to change the defaults on the adapter card if you want to disable the floppy drive or set an alternate address. --------------------------------------------------------------------------- CONFIGURE THE ADAPTER CARD --------------------------------------------------------------------------- If you are installing the Western Digital WDAT-240 adapter card, chances are you do not need to configure it. You only need to change the default jumper settings if you want to disable the floppy drive controller or set an alternate address at 370-377. 2 4 o Þ W1 o Þ 1 3 Default Configuration 2 4 2 4 2 4 Þ o W2 Þ Þ W2 o Þ W2 Þ o Þ Þ o Þ 1 3 1 3 1 3 Floppy controller Floppy controller Floppy controller enabled, primary enabled, secondary at secondary address 3F0-3F7 address 370-377 address disabled The WDAT-240 adapter card has two jumper locations: W1 and W2. By moving the jumper "shunts" you can change the definition of the hardware attached to your computer. You only need to change the W2 jumper if your system set up and hardware differ from the standard installation. To change the jumper settings, carefully align the jumper shunt over the new pins and push gently straight down until the shunt is firmly seated. If you need to change the adapter card configuration, do so before attaching any cables or installing the card into the card slot. --------------------------------------------------------------------------- JUMPER SETTINGS --------------------------------------------------------------------------- The jumper shunt on pins 3 and 4 of W1 is the factory default setting. You only need to change W1 if you are using the adapter card for a single Conner drive installation in an authentic IBM PC/AT. You cannot install the Caviar drive as a second drive in this configuration. For more information on Western Digital adapter cards, contact the Western Digital Literature Distribution Department and request a copy of the AT Host Adapters Installation Guide (part number WDATHAIG). --------------------------------------------------------------------------- INSTALL THE ADAPTER CARD --------------------------------------------------------------------------- 1. Locate a 16-bit card slot in your system. Select a slot as close to the drive(s) as possible. Refer to your system manual if necessary to identify a 16-bit slot. 2. Attach the 40-pin interface cable from the intelligent drive to the hard drive connector on the adapter card. Do not force the cable and connector. Pin 20 of the connector is blocked (keyed) to prevent incorrect connection. 3. If you are also connecting your floppy drive(s) to the adapter card, attach the 34-pin connector from the floppy drive(s) to the floppy connector on the adapter card. 4. Loosen the retaining screw at the end of the selected card slot that secures the card slot cover to the back panel. 5. Hold the top corners of the adapter card and insert it into the card slot, firmly seating the card connectors into the card slot. 6. Slip the plastic mounting clip at the end of the adapter card under the loosened screw located at the end of the card slot. 7. Secure the screw with the screwdriver. Once the adapter card is connected and installed, close the computer case according to the instructions in your system manual. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ PREPARING THE CAVIAR DRIVE FOR USE ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ YOUR CAVIAR DRIVE HAS BEEN LOW-LEVEL FORMATTED. The hard drive is ready to set up and is defect-free. The drive needs to be high-level formatted so it is able to accept files. This section of the Installation Guide provides the basics for preparing your drive. You need to consult your operating system documentation for complete information on preparing your drive for use with your operating system. Your computer operating system provides an initial set up utility, which is either ROM-based or on floppy diskettes. The system set up procedures vary from system to system, but each set up procedure allows you to tell the system what type of hardware you are using. Follow the setup instructions in your operating system manual (MS-DOS or other operating system). =========================================================================== SELECTING YOUR DRIVE TABLES =========================================================================== One step in the setup procedure asks you to specify the type of drive used in your system. o If you are installing the 40 MByte drive in your system, you need to select DRIVE TYPE 17 from the drive tables displayed during the set up utility. Type 17 typically defines a drive with 977 cylinders, 5 heads, and 17 sectors per track. o There is no standard drive type for the 80 MByte drive. Below are some suggested drive tables. Use your set up utility to examine the available drive tables. Choose a table that comes as close as possible to the recommended parameter (980x10x17). Do not exceed the total number of sectors available on the drive, or 166,628 sectors. To calculate the number of sectors available, multiply the number of cylinders by the number of heads by the number of sectors on each track. For example: 980 x 10 x 17 = 166,600. The table below shows the number of sectors for several different setups. 80 MByte Drive Tables Cylinders Heads Sectors/Tracks Sectors/Drive ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: 980 10 17 166,600 (85.3 MB) 640 10 26 166,400 (85.2 MB) 841 6 33 166,518 (85.3 MB) 980 5 34 166,600 (85.3 MB) 832 6 33 164,736 (84.3 MB) 1024 9 17 156,672 (80.2 MB) =========================================================================== PARTITIONING THE DRIVE =========================================================================== You may need to partition your drive(s) to overcome certain limitations of your DOS version. Partitioning allows you to divide your 40 or 80 MByte disk into multiple partitions, which function as separate disk drives. Use the DOS fdisk command to display a series of menus that help you partition your hard disk for MS-DOS. To partition your intelligent disk: 1. Insert your DOS system diskette into drive A. 2. Reboot the system by simultaneously pressing [CTRL], [ALT], and [DEL]. 3. Type fdisk at the A: prompt. 4. Press [RETURN]. 5. Follow the default options. For more information, refer to your DOS manual. DOS versions 3.3 and higher allow you to create a primary partition, create an extended partition, change the active partition, delete a partition, and display partition data. Your version of DOS determines how you can partition your disk(s). o If you have a DOS version earlier than 3.3, you can only address 32 MBytes maximum on your drive. You cannot partition the drive(s), without third party software. We recommend you upgrade to DOS 3.3 or above. o If you have DOS version 3.3 or above (less than version 4.0), DOS allows you to partition larger drives into logical disk drives with a maximum of 32 MBytes per partition. o If you are working with DOS version 4.0 or greater, you can use a disk drive of any size. You are not limited to 32 MBytes. =========================================================================== FORMATTING THE DRIVE =========================================================================== Fdisk automatically assigns drive IDs to the partitions. If you have two drives, fdisk specifies C: as the first partition of the first drive, and D: as the first partition of the second drive. Subsequent drives are then ordered by letter in order of their assignment. Refer to your system manual for more information on partitioning drives. Just as you need to format a floppy diskette before it can accept files, you need to high-level format your Caviar drive to prepare it to receive files. YOU DO NOT NEED TO DO A LOW-LEVEL FORMAT. If at some later time you need to perform a low-level format, contact Western Digital Technical Support for information on this procedure. To high-level format the first logical drive (the "C" drive): 1. Type FORMAT C:/S at the A: prompt. 2. Press [RETURN]. If you designated other drives or partitions during the fdisk routine, you need to format those drives as well. For example, type FORMAT D: at the prompt and then press [RETURN]. Continue the format process until you have formatted all drives. When the formatting process is complete, copy all DOS files from the floppy onto your hard drive. For more information on formatting, refer to your operating system documentation. =========================================================================== PREPARING THE CAVIAR DRIVE FOR A NOVELL NETWORK =========================================================================== If you are installing Novell, you must COMPSURF the Caviar drive using the following parameters: o Format the disk NO o Maintain the current media defect list NO o Enter media defects NO o Number of sequential passes DEFAULT o Number of I/O random test DEFAULT o Are parameters correct YES After running COMPSURF on the Caviar drive, enter NETGEN. Refer to your Novell installation manual for more information on COMPSURF and NETGEN. =========================================================================== BOOTING THE SYSTEM =========================================================================== After you have properly formatted your drive(s), you are ready to use your system. Install the operating system on your intelligent drive and boot your system from your active DOS drive. Be sure to remove any diskettes from drive A: before booting. To boot the system: 1. Simultaneously press [CTRL], [ALT], and [DEL]. 2. The system should respond, and your monitor should display C:\. Refer to your system documentation for more information on booting your system. If your system will not boot, or if you are unable to make the new drive the current drive, refer to your operating system documentation to be sure that you ran the system utility correctly, specified the correct drive tables, and that you partitioned and formatted your hard disk(s) correctly. If your system still won't boot, you may have improperly installed or connected your hard drive. Re-read the installation instructions provided in this manual to be sure that you installed and connected everything properly. Refer to the Troubleshooting section of this manual for more information. It is extremely important to regularly back up the data on your hard disk to floppy diskettes or tape. Data can be damaged or lost due to a number of unanticipated factors. Consult your operating system documentation for back up instructions and procedures. There are also a number of commonly available back up utilities on the market that allow you to save copies of your work onto floppy diskettes or another type of magnetic media. =========================================================================== AUTOMATIC HEAD PARK FEATURE =========================================================================== The Caviar drive provides an automatic feature that parks the drive heads when the system power is turned off. If you need to move your system, be sure to turn the system power off. The drive heads are then moved to a safe, non-data area, and the heads are locked into place. This helps protect the disk media and the heads from accidental damage due to vibration, moving, or shipping. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ TROUBLESHOOTING ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This section lists procedures to resolve any problem you may encounter with the Caviar drive. o Re-read the installation instructions provided in this manual to be sure that you followed the instructions correctly and included all hardware necessary. o Refer to your system documentation to be sure that you followed the set up procedures correctly. o Make sure that you formatted and partitioned the intelligent drive and any additional drive with the DOS fdisk and format commands (or equivalent utilities). Refer to your operating system documentation to check these procedures. o Check the physical installation of your system. Check the following: - Are the jumper selections on the drive correct for your installation? - Are the cables correctly connected to all components? - Check the adapter card, if it is installed.
