Hard Drive Installation and Support

you will learn
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
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
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
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 drive6
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
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
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 drive20
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
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
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
