Solving Technical Problems
14
The COMBO drive is not
detected by the computer.
After installing the COMBO
drive, the PC gets slower.
◆ Check that the power, audio and IDE cables are
correctly connected to the computer.
◆ Change the IDE cable and reconnect it to the computer.
Preferably, connect a second IDE cable to the COMBO
drive in master mode; see page 7 for further details.
◆ Check the position of the jumper in the master/slave
select terminal.
Problem Meaning / Solution
The COMBO drive is not
recognized by MS-DOS. ◆ Reinstall the device driver or update it with the latest
version by downloading it from the Samsung Web site.
The COMBO drive is not
detected by Windows. ◆ This case may occur when there is a Windows
installation problem; reinstall Windows.
No sound is heard from an
audio CD. ◆ Check whether the audio cable is correctly connected
to the sound output terminal on the COMBO drive and
the sound card CD-IN terminal.
◆ Check that the sound card is operational.
◆ Adjust the volume control.
A CD is not read or is read too
slowly. ◆ Install the latest version of the device driver.
◆ Check whether the CD is of good quality and clean it,
if necessary.
When the MPEG software plays
a Video CD, the pictures are not
regular and the running speed is
too slow. ◆ Adjust the size of the replay screen.
◆ After checking the display resolution, adjust it, if
necessary.
The Disc is not in message is
displayed even though a disc
has been inserted. ◆ The computer may not recognize the disc if you start
playback too quickly after inserting the disc.
Open and close the disc compartment and try again.
◆ Clean the disc and try again.
The COMBO drive is not
detected after it is connected to
a sound card. ◆ The interface mode of the sound card is AT-BUS.
You must therefore connect the COMBO drive to the
IDE port on the PC mother board, rather than to the
sound card, or install an IDE-compatible sound card.
The disc compartment will not
open. ◆ Check that the power cable is correctly connected.
◆ Power off and disconnect the PC. Insert a pin or
unfolded paper clip in the emergency hole and push
firmly until the disc compartment opens.
