User's Manual
Procedure
The files on the hard disk drive may be
fragmented - in this instance you should run the
disk Defragmentation utility to check the
condition of your files and the hard disk drive.
Please refer to the operating system's
documentation or online Help File for further
information on operating and using the
Defragmentation utility.
As a last resort you should reformat the hard disk
drive and then reload the operating system and
all other files and data. If you are still unable to
resolve the problem, contact your reseller, dealer
or service provider.
Procedure
Make sure the drive's disc tray is securely closed
- press it gently into the computer until it clicks
into place.
Open the drive's disc tray and ensure the CD,
DVD, or HD DVD is properly seated - it should lie
flat with the label facing upwards.
A foreign object in the drive's disc slot could
block laser light from reading the CD, DVD, or
HD DVD - remove any foreign objects or
obstructions that may be present.
Check whether the CD, DVD, or HD DVD is dirty
- if it is, wipe it with a clean cloth lightly dipped in
water or a neutral cleaner. Please refer to the
Media care section in Chapter 4 for further details
on cleaning the media.
The computer's software or hardware
configuration may be causing a problem - ensure
that these configurations match the requirements
of the CD/DVD/HD DVD media (refer to the CD's,
DVD's, or HD DVD's documentation if available).
