These jumpers select options on the hard drive. Your hard drive may have either a 6-pin or 10-pin jumper block. The first 6 pins on each jumper block are identical. The additional four pins on the 10-pin jumper block are reserved for future enhancements. The Western Digital hard drive is factory set for single drive installation with a jumper in the neutral storage position (across pins 5-3 or 6-4). The Cable Select jumper option is usually not required. It needs special support in your system hardware. Single Hard Drive Installations ------------------------------- If installing your new Western Digital hard drive as the only hard drive in your system, leave the jumper in the neutral storage position for possible future use. Jumpers are not required for single hard drive installations. Dual Hard Drive Installations ----------------------------- If installing your new Western Digital hard drive with an existing drive on the same IDE interface cable, use a jumper to designate the master (C:) and the slave (D:) drive. Neutral storage placement in this position, the jumper has no effect on hard drive operation. If installing your new Western Digital hard drive with an existing drive on separate IDE interface cables, leave the jumper in the neutral storage position for possible future use. The system recognizes each drive as a single, stand-alone drive. Master/slave jumper settings are only used when there are two devices on the same IDE interface cable. Note for Apple Users: Apple systems do not support master/slave configurations. You can only install one EIDE hard drive to each port. This jumper should be repositioned to select the following options: - To designate the Western Digital hard drive as the master drive in a two-drive system, place the jumper on pins 5-6. - To designate the Western Digital hard drive as the slave drive in a two-drive system, place the jumper on pins 3-4. If installing your new Western Digital hard drive with a non-Western Digital hard drive, obtain jumper configuration information from the EZ-Drive software diskette, or your original drive manufacturer. Setting the Jumper: Carefully place the jumper over the two pins. Push the jumper into place until it is firmly seated against the base of the jumper block.

Single Drive Mode ----------------- If you are installing the Caviar drive as the only intelligent drive in the system, you do not need install jumpers on the J8 connector. This is considered a standard single drive installation, and no jumpers are required. Note that even with no jumper installed, the Caviar checks the DRIVE ACTIVE/SLAVE PRESENT (DASP) signal to de- termine if a slave intelligent drive is present. 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 the J8 connector need to be configured for the dual installation. Master Drive Mode ----------------- To designate the drive as the master, place a jumper shunt on pins 5-6. With the Caviar configured as the master drive, the Caviar assumes that a slave drive is present. The jumper on pins 5-6 is optional if the slave drive follows the same protocol (Common Access Method AT Bus Attachment) as the Caviar. Slave Drive Mode ---------------- To designate the drive as the slave, place a jumper shunt on pins 3-4. When the Caviar is configured as the slave drive, the Caviar delays spin up for three seconds after powerup reset. This feature prevents overloading of the power supply during powerup. Cable Select (CSEL) ------------------- Caviar also supports the CSEL signal on the drive cable as a drive address selection. Place a jumper shunt on pins 1-2 to enable this option. When enabled, the drive address is 0 (Master) if CSEL is low or 1 (Slave) if CSEL is high.

HARDWARE INSTALLATION --------------------- Before you begin, gather these supplies: - Computer system manual - Operating system installation disks or CD-ROM - Operating system manual - Small Phillips screwdriver and flat-blade screwdriver - Bootable DOS disk or Windows 95 or 98 startup disk Be sure to write down your serial and model numbers and the CCC code. These numbers are located on the drive label. Create a Bootable DOS Disk -------------------------- For single hard drive installations, you must have a bootable DOS disk to install your new hard drive with EZ-Drive. Disk 1 of your standard DOS installation disk set is a bootable disk. If you do not have your original DOS installation disks, you can create a bootable DOS disk if you have a bootable C: hard drive. 1. Insert a blank floppy disk into drive A. 2. At the C: prompt, type format a:/s. Press ENTER. Create a Windows 95 or 98 Startup Disk For Windows 95 or 98 systems, you must have a bootable DOS or Windows 95 or 98 Startup disk to install your new hard drive with EZ-Drive. If using Windows 95 or 98, you should create a Windows 95 Startup disk. To create a Windows 95 or 98 Startup disk you must have a bootable C: hard drive. 1. Insert a blank floppy disk into drive A. 2. From Windows 95 or 98, click My Computer. 3. Click Control Panel. 4. Click Add/Remove Programs. 5. Select the Startup Disk tab. 6. Click Create Disk. Follow the prompts to create a Windows 95 Startup disk. Back Up Existing Drives ----------------------- Protect your data by backing up your existing hard drive before installing your new Western Digital hard drive. Save the data to removable media such as floppy disks or tape. Most operating systems include a backup utility. Consult your operating system or utilities documentation for backup instructions. Unpacking and Handling the Hard Drive ------------------------------------- Western Digital hard drives are precision instruments and should be handled with care during unpacking and installatiom. Hard drives are typically damaged by rough handling, shock, vibration, or electrostatic discharge (ESD). Be aware of the following precautions when unpacking and installing your Western Digital hard drive. - Do not unpack your hard drive until you are ready to install it. After your WD hard drive is unpacked, place the drive on the static shielding bag on a clean, level, padded work area. Your Western Digital hard drive comes packaged in a static shielding bag. - Save the packing materials in case you need to return your hard drive. Shipping your hard drive in anything other than the original packaging or WD supplied or approved materials will void your warranty. - To avoid ESD problems, ground yourself by touching the metal chassis of the computer before handling the hard drive. Articles of clothing generate static electricity. Do not allow clothing to come in direct contact with the hard drive or circuit board components. - Handle the hard drive by the sides only. Avoid touching the circuit board components. - Do not drop or knock the hard drive. - Before installation, do not stack hard drives or stand your Western Digital hard drive on its edge. You can, however, mount your hard drive horizontally or vertically. - Do not remove the tape seal or any labels from the drive; the warranty will be void. Open Your Computer ------------------ 1. Turn off your system. 2. Discharge static electricity by touching the metal chassis of the computer. 3. Unplug your computer. 4. Remove the computer's outside cover. Consult your computer system manual for details. Be sure to keep all screws and other parts together for easy reassembly. Removing Existing Hard Drives ----------------------------- If replacing an existing drive, follow these instructions. IMPORTANT Be sure to turn off the system power and unplug the power. 1. Disconnect the power cord and IDE interface cable. 2. Remove screws and slide the hard drive out of the drive bay. Handle the hard drive with care. Be careful not to scratch, tear, or remove the tape seal on the drive; this will void the warranty. If installing your new Western Digital hard drive with an existing drive on separate IDE interface cables, leave the jumper in the neutral storage position for possible future use. The system recognizes each drive as a single, stand-alone drive. Master/slave jumper settings are only used when there are two devices on the same IDE interface cable. Note for Apple Users: Apple systems do not support master/slave configurations. You can only install one EIDE hard drive to each port. If installing your new Western Digital hard drive with a non-Western Digital hard drive, obtain jumper configuration information from the EZ-Drive software diskette, or your original drive manufacturer. Mounting Hardware ----------------- Inspect the bay to determine whether it is a 3.5-inch or 5.25-inch bay. The WD hard drive fits into a 3.5-inch bay. If installing the WD hard drive i- a 5.25-inch bay, you must install 5.25-inch mounting hardware. If you do not have mounting brackets, contact your system manufaturer, your local computer dealer, or call Western Digital's technical support. Drive Rails (Optional) ---------------------- Some computer systems have 5.25-inch drive bays that require unique sliding drive rails to complete the hard drive installation. Because each system manufacturer has a different type of drive rail, rails are not included with WD hard drives. If your system requires drive rails, contact the computer system manufacturer. The following list provides phone numbers for common system manufacturers. Installing your new WD hard drive --------------------------------- IMPORTANT Your system must be turned off before connecting or disconnecting the power supply to the drive. 1. Thread the cable through the empty drive bay and slide in the WD hard drive. 2. Attach the end of the 40pin IDE interface cable to the 40-pin connector on the back of the WD hard drive. Match pin socket 1 on the IDE cable (indicated by a color stripe on the cable) to pin 1 on the Western Digital hard drive. Note for Apple Users: Use an Apple supplied interface cable only. Pin 40 on an Apple supplied interface cable is indicated by a color stripe on the cable. 3. Attach the computer system power supply cable to the 4 pin power connector on the back of the Western Digital hard drive. The 4 pin connector is keyed to ensure proper insertion. 4. Single Installations: Attach the end of the 40 pin IDE interface cable from the Western Digital hard drive to the 40 pin connector on the motherboard or controller card. Match pin socket 1 (indicated by a color stripe on the cable) on the IDE interface cable (next to the drive power connector) to pin 1 on the motherboard or controller card. Dual Installations ------------------ Connect the two hard drives by using a 40 pin, three-connector IDE interface cable. Match pin socket 1 on the 40 pin, three-connector IDE cable to pin 1 on the drive's connector. 5. Mount the WD hard drive in the drive bay using the four mounting screws provided. For proper grounding, be sure to use all four screws. If your system does not have an extra power connector, purchase a Y-adapter from your computer dealer. 6. Check all cable connections. Replace the system cover. 7. Plug in your computer. 8. See the EZ-Drive Software Installation section for hard drive setup instructions. ********************************************************************** F E A T U R E S ********************************************************************** WESTERN CAVIAR INSTALLATION GUIDE 79-850086-003 SO225 11/98 SOFTWARE INSTALLATION --------------------- Before partitioning and formatting your new hard drive, you need to configure your system BIOS. Your computer system provides an initial setup ability (CMOS Setup) that allows you to tell the system what type of hardware you are using. Configuring the System BIOS --------------------------- Each system BIOS is different. The information supplied here is not meant to be followed step-by-step; it is provided only as a guideline. Refer to your system manual for details. 1. Enter your CMOS setup program (sometimes called the Setup program). Refer to your system manual for instructions IMPORTANT If your system does not respond (locks up) on inintial boot, see Operating System and System BIOS Limitations. 2. Enable options such as LBA or Translation Mode. If you do not have either option, you need to use EZ-Drive to install your new hard drive, upgrade the system BIOS, or install an EIDE controller card with onboard BIOS that supports the full drive capacity. 3. Select an auto config drive type. The full capacity of your drive should display. If your system BIOS does not have an auto config drive type, select user defined and enter 1023 cylinders, 16 heads, and 63 sectors for the drive parameters. Selecting user defined ensures that EZ-BIOS will install on your system. If your system BIOS does not have auto config or user defined, select Type 9. Selecting Type 9 ensures that EZ-BIOS will install on your system. EZ-Drive Software Overview -------------------------- EZ-Drive is a software utility that quickly and easily partitions and formats your new hard drive. If needed, EZ-Drive installs added code in the boot sector of your hard drive if it determines that your system BIOS does not support the full capacity of your hard drive. EZ-Drive software is included with the Western Digital hard drive to: - Overcome the 8.4 GB, 2.1 GB, and 528 MB system BIOS limitantions. - Partition and format your new hard drive. - Copy system files needed to boot your new hard drive. - Copy the contents of an existing hard drive onto your new hard drive (optional). If you did not receive EZ-Drive software, you can download it from the Western Digital web site at WWW.WESTERNDIGITAL.COM. Operating System Compatibility ------------------------------ You Can use EZ-Drive software with these operating systems: - DOS 5.0 and above - Windows 98 - Windows 95 - Windows NT 3.51 and 4.0 (do not use alternate jumper settings for hard drives >4.2 GB ) - Windows 3.1x and Windows for Workgroups 3.11 - OS/2 Warp 3.0 and 4.0 IMPORTANT Windows NT 3.51 and 4.0 and OS/2 Warp 3.0 and 4.0 DO NOT support the EZ-Drive floppy boot protection scheme. If using one of these operating systems, you must disable floppy boot protection immediately after installing EZ-Drive. You CANNOT use EZ-Drive with these operating systems: - Macintosh - Novell NetWare - Unix If using a Macintosh computer, partition and format your new hard drive with the Apple Drive Setup software. If using Unix or Novell NetWare, consult your operating system manual to partition and format your hard drive. EZ-BIOS ------- EZ-BIOS is code that installs on the boot sector of the hard drive if your system BIOS does not support the full capacity of your hard drive. EZ-BIOS helps your system overcome the 8.4 GB, 2.1 GB, and 528 MB barriers. See Operating System and System BIOS Limitations. EZ-Drive determines if your system BIOS as set supports the full capacity of your hard drive. If it does, EZ-Drive only partitions and formats the hard drive; it does not install EZ-BIOS. If it does not, EZ-Drive partitions and formats the hard drive and installs EZ-BIOS on the boot sector of the hard drive. Partition and Format -------------------- EZ-Drive automatically partitions and formats your hard drive. You can accept the EZ-Drive default partition sizes or create custom partitions. Since it is difficult to determine if your system BIOS supports 8.4 GB or larger hard drives, we recommend using EZ-Drive 9.06W or later versions. It is a fast and easy way to partition and format your new hard drive. IMPORTANT. DOS, Windows 3.1x, and early versions of Windows 95 use FAT16 file systems which have a 2.1 GB partition limit. You must create multiple partitions on hard drives larger than 2.1 GB. Copying System Files -------------------- EZ-Drive copies system files needed to boot your new hard drive. These files can be copied from your existing hard drive or diskette. Copying Data from an Existing Hard Drive to a New Hard Drive For DOS, Windows 3.1x, Windows 95, Windows 98, and Windows NT systems, use this feature to copy the contents (operating systems, data, hidden files, and programs) of an existing hard drive to your new hard drive. If you use this feature, you do not need to reinstall your operating systems and software programs on your new hard drive. Note: EZ-Drive cannot copy OS/2 HPFS and Windows NT NTFS partitions (some OS/2 and Windows NT systems have these partition types). Software Compatibility ---------------------- Converting Ontrack Disk Manager Partitions to EZ-Drive Partitions: Ontrack Disk Manager and EZ-Drive cannot coexist in the same system. If your existing drive has Ontrack Disk Manager installed, use the EZ-Drive Fully Automatic Install to set up your new hard drive and convert Ontrack Disk Manager boot code to EZ-BIOS. Even though EZ-Drive converts Ontrack Disk Manager partitions to EZ-BIOS partitions without data loss, be sure to back up your existing hard drive before proceeding. Data Compression Software: EZ-Drive is compatible with Stacker, Drivespace, and Doublespace disk compression utilities. Other data compression software may not be compatible. Always back up your data before using any data compression software. Diagnostic Software: Some system manufacturer diagnostic software may be incompatible with EZ-Drive. Hard Disk Device Drivers: Products that use their own hard disk device drivers such as third-party disk controllers and some caching controllers may not be compatible with EZ-Drive. Memory Managers: EZ-Drive is fully compatible with the standard memory managers that come with DOS and Windows. However, EZ-Drive loads in conventional memory and may not be compatible with some third-party memory managers. Using EZ-Drive Software ----------------------- Single Hard Drive Installation ------------------------------ Follow the steps outlined below to set up your hard drive for use in a one-drive system. These steps are a guideline. Depending on your system and hard drive, the EZ-Drive screens you see may be different than those presented here. If installing your hard drive in a multiple-drive system, see the Adding Your New Hard Drive with an Existing Hard Drive section. IMPORTANT: Windows NT 3.51 and 4.0 and OS/2 Warp 3.0 and 4.0 DO NOT support the EZ-Drive floppy boot protection scheme.

Refer to your operating system documentation to check these procedures. - If using DOS 3.3 and above, be certain to make one partition active during formatting. - Check the physical installation of your system to make sure that: - Jumper selections on the drive are correct for your installation. - Cables are correctly connected and seated. - Adapter card, if required, is properly seated, connected, and configured. - Power is properly connected to your system and the system is plugged in. Operating System and System BIOS Limitations -------------------------------------------- Computer operating systems and system BIOSs have separate limitations that are related to specific hard drive capacities. Three capacity points that can affect how your operating system and system BIOS support your hard drive are 8.4 GB, 2.1 GB, and 528 MB. A brief description of these limitations follows. 8.4 GB Barrier: There is an 8.4 GB hard drive limitations on some traditional system BIOSs. To access the full capacity of 8.4 GB and larger hard drives, your system BIOS must support extended BIOS functions, and your operating system must recognize extended BIOS functions. It is difficult to determine if your system BIOS supports 8.4 GB or larger hard drives. We recommend using EZ-Drive 9.06W or later to ensure support of the full capacity of your hard drive. 2.1 GB Barrier: Some computer systems built before early 1996 do not support hard drives with more than 4095 cylinders (hard drives larger than 2.1 GB), unless you update the system BIOS, install an EIDE controller card with onboard BIOS, or install third-party software such as EZ-Drive. 528 MB Barrier: Most computer systems built before August 1994 do not support hard drives larger than 528 MB, unless you update the system BIOS, install an EIDE controller card with onboard BIOS, or install third-party software such as EZ-Drive. To determine if your system BIOS supports the full capacity of your hard drive, EZ-Drive compares the system CMOS settings to the actual drive size. If the values match, EZ-Drive only partitions and formats the hard drive; it does not install EZ-BIOS. If the values do not match, EZ-Drive partitions and formats the hard drive and installs EZ-BIOS on the boot sector of the hard drive. Operating System and System BIOS Limitations for 8.4 GB and Larger Hard Drives ------------------------------------------------------------- The following is required to access the full capacity of an 8.4 GB or larger hard drive: - A system BIOS that supports extended functions - an operating system that recognizes extended BIOS functions The limitations of your system BIOS and your operating system combined determine your overall system limitation. For example, if your operating system recognizes extended BIOS functions, but your system BIOS has a 2.1 GB drive barrier, you are limited to your system BIOS's 2.1 GB drive barrier. Conversely, if your operating system does not recognize extended BIOS functions, but your system BIOS supports 8.4 GB hard drives, you are limited to your operating system's capability. Your system limitation is based on the lowest functioning barrier. Since it is difficult to determine if your system BIOS supports your 8.4 GB or larger hard drive, we recommend using EZ-Drive 9.06W to support the full capacity of your hard drive. Another option is to upgrade your system BIOS. A properly upgraded system BIOS will support the full capacity of your hard drive if used with an operating system that recognizes extended BIOS functions. Contact your system manufacturer for more information. Operating systems that recognize extended BIOS functions: - Windows 95 - Windows 98 Operating systems that do not recognize extended BIOS functions. - DOS 6.xx and earlier - Windows 3.1x - Windows NT - Novell NetWare - OS/2 Warp Operating System Limitations and Exceptions DOS 6.xx and earlier Windows 3.1x 8.4 GB maximum capacity limit. Hard drive capacities larger than 8.4 GB are recognized as 8.4 GB. Windows NT Windows NT 4.0 with Service Pack 3 supports hard drive capacities larger than 8.4 GB. Novell NetWare Novell NetWare 4.11: Drivers are available to support capacities larger than 8.4 GB. Novell NetWare 5 supports 8.4 GB and larger hard drives. OS/2 Warp Requires patch to support 8.4 GB or larger hard drives. System BIOS Limitations for Hard Drives Larger Than 2.1 GB ----------------------------------------------------------- IMPORTANT If you installed a 2.5 GB or larger hard drive and your system does not respond (locks up) on initial boot, read this section. Hard drives larger than 2.1 GB have more than 4095 cylinders. On some systems, the system BIOS cannot properly recognize hard drives with more than 4095 cylinders. You will know if your system BIOS has this limitation after installing your drive if: - Your operating system shows a much smaller drive capacity than the actual drive capacity. - Your system locks up on initial boot, preventing you from accessing CMOS setup. Operating System Shows a Much Smaller Capacity ---------------------------------------------- If your operating system shows a much smaller drive capacity, use EZ-Drive to overcome the 2.1 GB BIOS limitation. Your System Locks Up on Initial Boot ------------------------------------ If you cannot access the CMOS setup because your system locks up on initial boot, follow the instructions below. 1. Turn off your system power, check the IDE interface cable and power supply cable. 2. Check jumper settings. 3. Turn on your system power. 4. Try to enter your CMOS setup and set the drive type to auto config. If your system still does not respond, your system BIOS may not support drives with more than 4095 cylinders. If this is the case, consider these solutions: A. Use EZ-Drive. If the system locks up and prevents entry to CMOS, you need to turn off your system power and disconnect the IDE interface cable from the system. - Enter your CMOS setup. Refer to your system manual for instructions. - Select the Hard Disk Type option for the new Western Digital hard drive. Select a user defined drive type and enter: 1023 cylinders, 16 heads, and 63 sectors. If your system does not have a user defined drive type, select Type 9. - Reconnect your IDE interface cable to the system. - Run EZ-Drive or boot to the EZ-Drive 9.06W diskette.These new settings allow your system to boot so that you can install EZ-BIOS to access the full capacity of the drive. - OR -If you do not have a user defined or Type 9 drive type, use option B, C, or D below to change the parameters reported to the BIOS. B. Upgrade your system BIOS A properly upgraded system BIOS will support the full capacity of your hard drive. Contact your system manufacturer and closely follow their specific instructions. See page 3 for a list of common system manufacturers and page 12 for BIOS upgrade sources with their phone numbers. C. Install an EIDE controller card with an onboard BIOS that supports hard drives larger than 2.1 GB. For 8.4 GB or larger hard drives, the EIDE controller card must support extended BIOS functions. D. Rejumper the drive as described on the following page and install EZ-Drive. With these alternate jumper settings, you MUST install EZ-Drive. If you move this hard drive to another system, you must put the jumper back to the standard position. Note for Windows NT Users: If your system locks up, and you are using Windows NT, do not use these alternate jumper settings. You need to either use the standard jumper settings on page 2 and select a user defined drive type in CMOS setup or upgrade your system BIOS to support the full capacity of your new hard drive. IMPORTANT These alternative jumper settings DO NOT work with Windows NT, Novell NetWare, or Unix. Single Drive: If you have a 2.5 GB or larger hard drive, your system locks up on initial boot, and the drive you are installing is the only drive in your system, set the jumpers in these positions. Dual (Master) Drive: If you have a 2.5 GB or larger hard drive, your system locks up on initial boot, and the drive you are installing is the master drive in a twondrive system, set the jumpers in these positions. CAUTION: Use these jumper settings only if you encounter the specific BIOS limitation (system locks up) described in this section. These jumper settings cause the drive to report 4092 cylinders (2.1 GB) rather than the actual drive capacity. If you use these jumper settings, you MUST install EZ-Drive to access the full capacity of your new hard drive. Dual (Slave) Drive: If you have a 2.5 GB or larger hard drive, your system locks up on initial boot, and the drive you are installing is the slave drive in a twondrive system, set the jumpers in these positions.
