Introduction This user’s guide presents the basics of hard drive installation and operation. It also provides the information specific to your hard drive, so you can make any necessary adjustments. If you have received this manual with a new system, keep this reference in case you decide to upgrade or reconfigure your system. If you are installing a new hard drive or replacing an old one, you need these: The new hard drive and the materials that shipped with it. The documentation that shipped with your computer. One of the following forms of operating system software that shipped with your system (only one combination): system diskette and Windows 95 CD; system diskette and the System CD (version 4.3 or more recent) or the Operating System CD; MS-DOS Setup diskettes. Note: You may have heard that it is important to park hard disk heads before moving a computer system. This is true, but the hard disk installed in your computer parks its heads automatically each time you shut down the system; no action on your part is necessary. Consequently, you should NEVER use a disk parking program with your system. On the other hand, the hard disk heads are comparatively unprotected while the computer is running. To avoid damaging the hard disk drive, NEVER move your system unless the power is off; even if you are only moving it to the other side of your desk.   Configuring the drive Because this drive can be used alone or together with another IDE drive, you must configure it according to your system’s setup. Decide how you plan to set up the new hard drive within your existing configuration. Before opening your system case, read and follow these preventions and precautions to prevent damage from static electricity. Caution! Preventing Static Electricity Damage The components inside your system are extremely sensitive to static electricity, also known as electrostatic discharge (ESD). Static electricity can cause irreparable damage to your system; however, if you follow these preventions and precautions, you should prevent such damage. Static Electricity Preventions 1. WEAR A GROUNDING WRIST STRAP (available at most electronic stores). 2. Turn off the system power. 3. Touch the back of the power supply fan, located on the back of the case. 4. UNPLUG ALL CORDS FROM WALL OUTLET. 5. Remove the system case cover. Static Electricity Precautions • Avoid static-causing surfaces such as plastic and styrofoam in your work area. • Remove parts from their antistatic bags only when you are ready to use it. Do not lay parts on the outside of antistatic bags since only the inside provides antistatic protection. • Always hold cards by their edges and their metal mounting bracket. Avoid touching components on the cards and the edge connectors that connect to expansion slots. • Never slide cards or other parts over any surface.   About master and slave drives The first (or a Single) drive is connected with an IDE cable to the system board’s Primary IDE controller and is considered the "master" drive on the Primary IDE controller. If you have an IDE CD-ROM drive, it is connected with an IDE cable to the system board’s Secondary IDE controller, making it the "master" drive on the Secondary IDE controller. In general, you can connect two more IDE drives to your system—one on each IDE controller; in which case, they become the "slave" drives. Each drive must be configured appropriately to work correctly with your system. The following table includes the most common configurations. Drive Set to Where it connects on the system board Single Single Primary IDE controller *Second "Slave" Primary IDE controller †Third "Master" Secondary IDE controller Fourth "Slave" Secondary IDE controller *When a second drive is installed, the single drive should then be set to "master." †An IDE CD-ROM drive is usually configured as the "master" drive on the Secondary IDE controller (see Third in the table above). In this case a third hard drive in your system would be configured as the Fourth (see table above). If you install a new drive with your old drive and you want the new drive to be the "master" drive on the Primary IDE connector, you need to remove the old drive and reconfigure it as the Second (see table above). If you have an IDE CD-ROM drive installed in your system, consult the user’s guide that shipped with your CD-ROM drive to make sure that the jumper settings on the CD-ROM drive do not need to be reset to share the Secondary IDE controller with a hard drive. The following illustration describes the jumper block used to configure the drive once you have decided how the drive needs to be configured for your system’s setup. Single drive jumper setting Master drive jumper setting Slave drive jumper setting Place the jumper over the pins that correspond to the setting you have selected. The drive is now ready to be installed in your system.   Setting the drive type After the hard drive is installed, your system’s Setup program identifies the hard drive type for each hard drive you are installing in your system. You may receive an error message about hard drive configuration when you boot up. This is to be expected because you just changed the hard drive setup. For instructions on accessing the Setup program, see the documentation that shipped with your computer. From the Setup program, scroll through the list and choose AUTO CONFIGURE to specify the drive type for each drive in your system. The system automatically determines the correct drive type. The system may appear to pause for a minute while it detects the drive type. If you prefer, you can manually enter the drive’s parameters (cylinders, heads, sectors, etc.). To manually enter the settings, choose USER DEF, and then tab over and type in each number. Parameters for several drives are shown in the following table. Caviar Drive Size Cyl. Heads Sectors LZ Write Precomp 21600 1600 3148 16 63 0 None 22000 2000 3876 16 63 0 None 33200* 3200 6296 16 63 0 None 34000* 4000 7752 16 63 0 None *Before setting the drive type for drives noted with an asterisk in the table above, consult "Larger capacity drives and LBA"—the next section.   Larger capacity drives and LBA If you install a 528MB or larger hard drive in your computer system, you can use AUTO CONFIGURE in the Setup program to configure the drive as long as your BIOS supports Logical Block Addressing (LBA). Many of the pre-PCI local bus systems do not have a BIOS that supports LBA. PCI models have a P in the model type: P4D-33, -66, -100; P5-60, -75, -90, -100, -120, -133. Earlier models did not include a P in the model number. To determine whether your system board’s BIOS supports LBA, consult the documentation that shipped with your system. Follow the instructions in the manual to make any necessary changes to your BIOS settings. Systems that support LBA have an option that allows you to enable LBA; the latest Setup programs have an option to set the IDE Translation Mode to Auto Detected. The newer Setup programs also have settings for Multiple Sector Setting and Fast Programmed I/O Modes. These options must be set to Auto Detected to ensure the proper operation of hard drives larger than 528MB. If your computer does not support LBA, you must manually enter the drive parameters for a 528MB or larger capacity hard drive instead of using AUTO CONFIGURE in the Setup program. The drive parameters you must use are in the following table. Caviar Drive Cyl. Heads Sectors LZ Write Precomp 2540 or larger 1023 16 63 0 None These settings allow the system to use only 503 or 504 MB of the hard drive’s capacity. This is a limitation of the system board’s BIOS, not your hard drive’s capacity.   Partitioning and formatting the hard drive For an operating system (such as MS-DOS or Windows) to store files on a hard drive, the disk must be partitioned and formatted. When you partition a disk, you designate the area(s) of the disk to be used for the operating system files. Windows uses the MS-DOS partition file FDISK.EXE. FDISK allows you to set up a primary DOS partition, extended DOS partitions, and logical drives within the extended DOS partitions. A primary DOS partition contains the essential files to boot your system from the hard drive (system files). To boot to Windows from your hard drive, you must have a primary DOS partition set to active. An Extended DOS partition is a portion of a hard drive where non-system files can be stored. Unlike a primary DOS partition, you cannot boot your system from an extended DOS partition, and your system does not require an extended partition to function. A Logical Drive is an area of an Extended DOS partition that you can set up to group directories and files; it does not increase disk storage capacity. You must set up an extended DOS partition before you can establish a logical drive. You can create up to 23 logical drives in an extended DOS partition. When you format a hard drive, you prepare the section that will receive files. Windows uses the MS-DOS file—FORMAT.COM—to format disks. The MS-DOS File Allocation Table (FAT) allows your system to address only about 2.1GB of hard drive space per partition. Although it uses LBA Translation Mode, the MS-DOS system is limited to recognizing only 2GB partitions. Because of this limitation and the size of this drive, your system—if it has LBA—configures two drives on the 2.5GB drive during the partitioning and formatting process. After your system recognizes the drive, it is ready to be partitioned and formatted. Even if you plan to run just one operating system (MS-DOS, for example), you must still create a partition.   Operating system backup software Your operating system backup software includes the FDISK and FORMAT files. It shipped with your system in one of three different ways as described below. First, determine which of the three possibilities is consistent with the media that shipped with your system and have the necessary diskettes and/or CDs readily available.   The system diskette and the Windows 95 CD If your computer shipped with Windows 95 installed, you can use the system diskette to partition and format your hard drive and the Windows 95 CD to install the Windows 95 operating system if necessary.   The system diskette and the System CD (version 4.3 or more recent) or the Operating System CD If your computer shipped with MS-DOS on the System CD or the Operating System CD, use the system diskette to partition and format your hard drive and either the System CD or the Operating System CD to install the MS-DOS and Windows operating system if necessary.   The MS-DOS Setup diskettes If your system shipped with the MS-DOS Setup diskettes, use the Setup diskettes to partition and format your hard drive and to install the MS-DOS operating system if necessary.   Partitioning the drive Two sets of steps are included in this section. Use the first set to partition the hard drive as the primary drive; use the second set to partition the hard drive as a secondary drive. All files are erased during this process.   To partition as the primary (boot) drive: Use these instructions if you have configured and installed your drive as the "master" drive on the Primary IDE controller. Place the system diskette or the MS-DOS Setup diskette in the 3.5-inch floppy drive. Start up the computer. An Important Note screen may appear. If so, press <Enter> to clear the screen and disregard the message at this point. The Main Menu screen appears. Using the arrow keys, highlight option 4, Exit. Press <Enter>. The A:\> prompt appears on the screen. Type: fdisk and press <Enter>. The following screen appears. Choose option 1, Create DOS partition or Logical DOS Drive from the FDISK Options menu, and press <Enter>. A message appears asking whether you want the primary DOS partition to be the maximum size available or a smaller size. Choose the appropriate option and press <Enter>. Remember that if you choose to make the primary DOS partition less than the maximum size, you must create an extended DOS partition to make full use of the drive. Set the primary DOS partition to active. When you are finished partitioning the drive, exit FDISK. Continue in the "Formatting the drive" section of this manual   To partition as a secondary drive: Use these instructions if you have configured and installed your drive as the "slave" drive on either the Primary or Secondary IDE controller or the "master" drive on the Secondary IDE controller (usually already used by the CD-ROM drive). The drive letters (for example, C: or D:) used in these steps assume that you are installing a second drive as "slave" on the Primary IDE controller. If you are installing a third or fourth drive, substitute the appropriate drive letters as necessary. With the system diskette or the MS-DOS Setup diskette in the 3.5-inch floppy drive, start up the system. If you are using the system diskette, the system starts up to a Main Menu screen. Choose option 4 to exit to the A:\> prompt. If you are using the MS-DOS Setup diskette, the system starts up to a Welcome to Setup screen. Press the <F3> key on your keyboard twice to exit to the A:\> prompt. At the A:\> prompt, type fdisk and press <Enter>. The following screen appears. Type: 5 and press <Enter>. Your computer recognizes the new hard drive as Disk 2, Drive D (your numbers and letters may differ depending on the number of hard drives already present in your system). Type: 2 (or the appropriate number of the hard drive you have just installed) and press <Enter>. The FDISK Options screen reappears. Type: 1 and press <Enter>. The Create Extended DOS Partition or Logical DOS Drive screen appears. Type: 2 and press <Enter>. The Create Extended DOS Partition screen appears. Press <Enter> to accept the default values for each option presented. When prompted, press <Esc> to continue. The Create DOS Partition or Logical DOS Drive screen reappears. Type: 3 and press <Enter>. The Create Logical DOS Drive(s) in the Extended DOS Partition screen appears. Press <Enter> to accept the default values for each option presented. When prompted, press <Esc> to continue. When you are finished partitioning the drive, exit FDISK. Continue in the next section of this manual.   Formatting the drive Use these steps to format the drive after using FDISK as instructed to partition the drive. Make sure your system diskette or your MS-DOS Setup diskette is still in the floppy drive and you are at the A:\> prompt. All files are erased during this process.   To format the drive: At the A:\> prompt, type: format c: (or the appropriate letter of the hard drive you have just installed) and press <Enter>. Note: If the drive you are formatting is the boot drive (usually the C: drive), type: format c: /s to format the drive as a boot drive. The format program asks if you wish to proceed with the format. Press <Y> to continue. When the hard drive is formatted, the system asks you to label the hard drive. Labeling is optional; you can press <Enter> to clear this question or type a label name and press <Enter>. The hard drive is ready to accept files for storage.   Troubleshooting If a hard drive fails to operate after you install it, verify your work with the instructions in this manual. Here are some potential problem areas: You entered the incorrect drive type number in the system Setup program. Try setting the drive to auto default and attempt to partition and format again. You haven’t made a partition with FDISK yet. Be sure to create at least one partition and activate the primary DOS partition. You did not properly format the drive. If you have more than one partition, remember to format separately each logical drive you create. You forgot to connect the drive to the power supply. You incorrectly connected the hard drive interface cable. Make sure the dotted or colored edge of the data (ribbon) cable connects to Pin 1 (usually closest to the power connector) at each connector. You incorrectly set the "master" or "slave" jumpers on the back of the hard drive. You may need to install a new cable. If you have an IDE CD-ROM drive on another controller, trade cables with the hard drive. If the hard drive works on the CD-ROM drive’s cable, the hard drive’s cable is defective. Install a new cable.   Notices   All rights reserved This publication is protected by copyright and all rights are reserved.
