The COMBO drive is not detected after it is connected to a sound card. Meaning / Solution x Check that the power, audio and IDE cables are correctly connected to the computer. x 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. x Check the position of the jumper in the master/slave select terminal. x Reinstall the device driver or update it with the latest version by downloading it from the Samsung Web site. x This case may occur when there is a Windows installation problem; reinstall Windows. x Check whether the audio cable is correctly connected to the sound output terminal on the COMBO drive and the sound card CD-IN terminal. x Check that the sound card is operational. x Adjust the volume control. x Install the latest version of the device driver. x Check whether the CD is of good quality and clean it, if necessary. x Check that the power cable is correctly connected. x 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. x Adjust the size of the replay screen. x After checking the display resolution, adjust it, if necessary. x 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. x Clean the disc and try again. x 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. 14 Technical Specifications SAMSUNG continually strives to improve its products.
