Using an optional external optical drive
Some external optical drives can only read information, but others can also write (burn) information
onto a blank disc.
Use these tips for best performance when using an external optical drive:
● When the battery is the only source of power, be sure the battery is sufficiently charged before
writing to media.
● Do not type on the keyboard or move the computer while an external optical drive is writing to a
disc. The write process is sensitive to vibration.
● Make sure you have installed the latest software updates for the drive.
● If the disc you are using is not clean, wipe it with a dry, lint-free, soft cloth.
An external optical drive supports one or more of the following disc technologies:
● CD—A compact disc stores data that is read by a laser from the optical disc drive. The following
CD formats are available:
◦ CD-Recordable (CD-R), which allows the computer to read information and to record
information one time on the CD. Once the information is recorded on the CD-R disc, it
cannot be changed or erased; it is permanent.
◦ CD-Re-Writable (CD-RW), which allows you to read information and record information
many times to the CD. Information on the CD can be erased.
● DVD—A digital video disc is a high-capacity optical disc. It can store more information than a
CD. A double-sided DVD can store up to 17 GB. The following DVD formats are available:
◦ DVD-Recordable (DVD-R or DVD+R), which allow the computer to read information and to
record information one time on the DVD. After the information is recorded on the disc, it
cannot be changed or erased; it is permanent. The DVDs can be used in DVD±R drives.
◦ DVD-Re-Writable (DVD-RW or DVD+RW), which allow to read information and record
information many times to the disc. Information on the disc can be erased. The DVDs can
be used in DVD±R drives.
● BD—a Blu-ray Disc holds more information than the other optical discs and they can used to
record, rewrite, and play back high-definition (HD) video.
Note the following when using BDs:
● Playing most BD movie titles on an external display requires an HDMI digital connection. The
computer can support up to 1080p resolution on an external display, which requires a 1080p-
capable HDTV or monitor.
● Attempting to play a BD movie simultaneously on both the internal and an external display may
cause an error, so choose only one.
● For copy protection purposes, Advanced Access Content System (AACS) keys are integrated
into the computer. AACS keys require occasional renewal to support playback of new BD movie
releases.
● If lines appear on the display when viewing a BD, they may be caused by interference from the
wireless network. To resolve the issue, close any open applications and turn off your wireless
feature.
