1 Handling drives
Drives are fragile computer components that must be handled with care. Refer to the following cautions
before handling drives. Additional cautions are included with the procedures to which they apply.
CAUTION To reduce the risk of damage to the computer, damage to a drive, or loss of
information, observe these precautions:
Before you move a computer or external hard drive from one location to another, initiate Sleep,
and allow the screen to clear.
Before handling a drive, discharge static electricity by touching the unpainted metal surface of
the drive.
Do not touch the connector pins on a removable drive or on the computer.
Handle a drive carefully; do not drop a drive or place items on it.
Before removing or inserting a drive, shut down the computer. If you are unsure whether the
computer is off or in Hibernation, turn the computer on and then shut it down through the operating
system.
Do not use excessive force when inserting a drive into a drive bay.
Do not type on the keyboard or move the computer while the optical drive (select models only)
is writing to a disc. The write process is sensitive to vibration.
When the battery is the only source of power, be sure that the battery is sufficiently charged
before writing to media.
Avoid exposing a drive to temperature or humidity extremes.
Avoid exposing a drive to liquids. Do not spray the drive with cleaning products.
Remove media from a drive before removing the drive from the drive bay, or traveling with,
shipping, or storing a drive.
If a drive must be mailed, place the drive in a bubble-pack mailer or other suitable protective
packaging and label the package “FRAGILE.”
Avoid exposing a drive to magnetic fields. Security devices with magnetic fields include airport
walk-through devices and security wands. The airport security devices that check carry-on
luggage, such as conveyor belts, use x-rays instead of magnetism and will not damage a drive.

2 Drive light
The drive light blinks when either the primary hard drive or an optical drive is being accessed. The drive
light changes to amber when the computer is dropped or moved while on battery power. The amber
color indicates that the hard drive has been temporarily parked by HP Mobile Data Protection 3D.

HP Mobile Data Protection 3D with digital accelerometer
HP Mobile Data Protection 3D with digital accelerometer protects the hard drive by parking the drive
and halting I/O requests when you
●Drop the computer.
●Move the computer with the display closed while the computer is running on battery power.
A short time after the end of one of these events, HP Mobile Data Protection 3D returns the hard drive
to normal operation.
NOTE Internal hard drives and optional MultiBay II hard drives (select models only) are
protected by HP Mobile Data Protection 3D. Hard drives that are connected to a USB port or in
an optional docking device are not protected.
For more information, refer to the HP Mobile Data Protection 3D online Help.
HP Mobile Data Protection 3D status
The drive light on the computer changes to an amber color to show that the drive is parked. You can
use Mobility Center to check whether drives are currently protected and whether a drive is parked:
●If the software is enabled, a green check mark is superimposed over the hard drive icon.
●If the software is disabled, a red X is superimposed over the hard drive icon.
●If the drives are parked, a yellow moon is superimposed over the hard drive icon.
If HP Mobile Data Protection 3D has parked the drive, the computer will behave in the following ways:
●It will not shut down.
●It will not initiate Sleep or Hibernation, except as noted below.
NOTE If the computer is running on battery power and reaches a critical battery level, HP
Mobile Data Protection 3D allows the computer to initiate Hibernation.
●It will not activate battery alarms set on the Alarms tab in Power Options Properties.
Before you move the computer, HP recommends that you either shut it down completely or initiate Sleep
or Hibernation.
HP Mobile Data Protection 3D software
The HP Mobile Data Protection 3D software enables you to perform the following tasks:
●Enable and disable HP Mobile Data Protection 3D.
NOTE Depending on your user privileges, you may not be able to enable or disable HP
Mobile Data Protection 3D.
●Determine whether a drive in the system is supported.

Replacing the hard drive
CAUTION To prevent system lockup and loss of information:
Shut down the computer before removing the hard drive from the hard drive bay. Do not remove
the hard drive while the computer is on, in the Sleep state, or in Hibernation.
If you are not sure whether the computer is off or in Hibernation, turn the computer on by pressing
the power button. Then shut down the computer through the operating system.
To remove the hard drive:
1. Save your work.
2. Shut down the computer and close the display.
3. Disconnect all external devices connected to the computer.

4 Optical drives (select models only)
The computer can read or write to optical drives as described in the following table.
Type of Optical Drive Read CD and
DVD-ROM
Write to CD-RW Write to DVD
±RW/R
Write to DVD+R
DL
DVD-ROM Drive Yes No No No
DVD/CD-RW Combo Drive Yes Yes No No
DVD±RW Double Layer Yes Yes Yes Yes
Some of the optical drives listed may not be supported by your computer. The listed drives are not necessarily all of
the supported optical drives.
An optical drive, such as a DVD-ROM drive, supports optical discs (CDs and DVDs). These discs are
used to store or transport information and to play music and movies. DVDs have a higher capacity than
CDs.
ENWW 11

Inserting an optical disc
1. Turn on the computer.
2. Press the release button (1) on the drive bezel to release the media tray.
3. Pull out the tray (2).
4. Hold the disc by the edges to avoid touching the flat surfaces and position the disc label-side up
over the tray spindle.
NOTE If the tray is not fully accessible, tilt the disc carefully to position it over the spindle.
5. Gently press the disc (3) down onto the tray spindle until the disc snaps into place.
6. Close the media tray.
NOTE After you insert a disc, a short pause is normal. If you have not selected a media player,
an AutoPlay dialog box opens. It prompts you to select how you want to use the media content.
12 Chapter 4 Optical drives (select models only) ENWW

Removing an optical disc when running on battery or
external power
1. Press the release button (1) on the drive bezel to release the media tray, and then gently pull out
the tray (2) until it stops.

edges of the disc. Hold the disc by the edges and avoid touching the flat surfaces.
NOTE If the tray is not fully accessible, tilt the disc carefully as you remove it.
3. Close the media tray and place the disc in a protective case.
ENWW Removing an optical disc when running on battery or external power 13

Removing an optical disc when no computer power is
available
1. Insert the end of a paper clip (1) into the release access in the front bezel of the drive.
2. Press in gently on the paper clip until the tray is released, and then pull out the tray (2) until it stops.
3. Remove the disc (3) from the tray by gently pressing down on the spindle while lifting the outer
edges of the disc. Hold the disc by the edges and avoid touching the flat surfaces.
NOTE If the tray is not fully accessible, tilt the disc carefully as you remove it.

Avoiding the Sleep state or Hibernation
CAUTION To prevent possible audio and video degradation, or loss of audio or video playback
functionality, do not initiate Sleep or Hibernation while reading or writing to a CD or DVD.
To prevent loss of information, do not initiate Sleep or Hibernation when writing to a CD or DVD.
If Sleep or Hibernation is initiated during playback of drive media (such as a CD or DVD), the computer
will behave in one of the following ways:
●Your playback may be interrupted.
●You may see a warning message asking if you want to continue. If this message is displayed,
click No.
●You may need to restart the CD or DVD to resume audio and video playback.
ENWW Avoiding the Sleep state or Hibernation 15

5 External drives
Removable external drives enable you to store and access information.
A USB drive can be added by connecting the drive to a USB port on the computer or on an optional
docking device.
An external MultiBay or MultiBay II supports any MultiBay or MultiBay II device, including the
following:
●1.44-megabyte diskette drive
●Hard drive module (a hard drive with an adapter attached)
●DVD-ROM Drive
●DVD/CD-RW Combo Drive
●DVD+RW/R and CD-RW Combo Drive
