Hard Drive Installation and Support


You will learn l.jpg
You Will Learn…

  • How to install a hard drive

  • How to use diagnostic software

  • How to recover lost data on hard drives

  • How to apply hard drive troubleshooting skills


Installing a hard drive l.jpg
Installing a Hard Drive

  • Set jumpers or DIP switches on the drive

  • Physically install an adapter card, cable, and drive

  • Change CMOS setup

  • Partition, format, and install software on the drive

  • Protect the drive and the PC against static electricity


Physical installation of ide or scsi hard drives l.jpg
Physical Installation of IDE or SCSI Hard Drives

  • IDE

    • Drive

    • 40-pin data cable

    • Possibly a kit to make drive fit in larger bay

  • SCSI

    • Drive

    • Cable compatible with host adapter

    • Possibly

      • External terminator

      • Host adapter

      • Kit to make drive fit the bay


Installing an ide hard drive l.jpg
Installing an IDE Hard Drive

  • IDE hard drives support up to four IDE devices on the same system

  • Four possible setups for each device

    • Primary IDE channel, master device

    • Primary IDE channel, slave device

    • Secondary IDE channel, master device

    • Secondary IDE channel, slave device

  • Place fastest devices on primary channel and slower devices on secondary channel

Installing an IDE Hard Drive

  • Take precautions

    • Have a good bootable disk or Windows 9x rescue disk

    • Read all documentation and check the setup of the computer

    • Visualize the entire installation

  • Understand the meaning of each DIP switch or jumper on the drive





Precautions for working with hard drives l.jpg
Precautions for Working with Hard Drives

  • Handle the drive carefully

  • Do not touch exposed circuitry or chips

  • Drain static electricity from your body and from the package containing the drive

  • If you must set it down, place the drive component-side up on top of the static-protective package on a flat surface

  • Do not place the drive on the computer case cover or on a metal table










Informing setup of the new hard drive l.jpg
Informing Setup of the New Hard Drive

  • Setup for hard drives less than 528 MB

    • Older BIOS: setup assumes use of CHS mode

    • New BIOS: select CHS mode or normal mode

  • Setup for large-capacity hard drives

    • Two ways BIOS relates to large capacity drives

      • LBA

      • Large mode

Informing Setup of the New Hard Drive

  • When BIOS does not support large-capacity hard drives:

    • Let the BIOS see the drive as a smaller drive

    • Upgrade the BIOS (best solution)

    • Upgrade the entire system board

    • Use software that interfaces between the older BIOS and the large-capacity drive (e.g., Disk Manager by OnTrack, SpeedStor by Storage Dimensions, EZ-Drive by StorageSoft)

    • Use an adapter card that provides the BIOS to substitute for system BIOS (e.g., Promise Technology, Inc.)


A note on moving a hard drive or changing bios l.jpg
A Note on Moving a Hard Drive or Changing BIOS

  • Backup up the data on the hard drive before you move it to avoid potential problems with:

    • Lost data

    • Inability to access the drive’s data

    • Different translation methods for LBA mode

  • Don’t change options in setup unless you are sure of what you are doing


Partitioning the hard drive l.jpg
Partitioning the Hard Drive

  • Partition table

    • Written at the very beginning of a hard drive

    • Describes number and location of all partitions

    • Identifies the boot partition

  • A drive must have one primary partition and can have one extended partition

    • The drive boots from the primary partition

    • The extended partition can be subdivided into several logical drive partitions
