Cannot eject compact disc (tray-load unit).

Cause

Solution

Disc not properly seated in the drive.

Turn off the computer and insert a thin metal rod into the
emergency eject hole and push firmly. Slowly pull the tray out
from the drive until the tray is fully extended, then remove
the disc.

Eject button may not be functioning.

Turn on your PC, and press the Eject button nearest the drive
to open the tray. If you suspect a problem with the actual Eject
button:

1.

Click 

Start

 and then 

Computer

.

2.

Right-click the CD or DVD drive you want to open.

3.

Select 

Eject

 from the menu.

CD-ROM, CD-RW, DVD-ROM, or DVD-R/RW drive cannot read a disc or takes too long to start.

Cause

Solution

Media has been inserted upside down.

Re-insert the media with the label facing up.

The DVD-ROM drive takes longer to start because it has to
determine the type of media played, such as audio or video.

Wait at least 30 seconds to let the DVD-ROM drive determine
the type of media being played. If the disc still does not start,
read the other solutions listed for this topic.

CD or DVD disc is dirty.

Clean CD or DVD with a CD cleaning kit, available from most
computer stores.

The driver may be corrupted or outdated.

desktop to open the Help and Support Center, type update
driver into the Search box, and then click

.

Windows does not detect the CD-ROM or DVD-ROM drive.

1.

Use Device Manager to remove or uninstall the device.

2.

Restart the computer and let Windows detect the CD or
DVD driver.

Recording or copying CDs is difficult or impossible.

Cause

Solution

Media installed upside down.

Ensure the disc is inserted with the label facing up and
centered in the tray.

Media is dirty or damaged.

Make sure the disc is clean and undamaged. If recording
stopped during a recording session, the disc may be
damaged; use a different disc.

Media already has recorded content.

When using a CD-R disc, make sure that it is blank when
recording music and is blank or appendable (with space to
add more data files) when recording data.

Wrong drive is being used.

Make sure the disc is in the correct drive and you specify the
same drive in the CD or DVD recording software.
