1. My CD-ROM drive doesn't read any CDs. It seems to spin up well but whentrying to access the CD, it says there is no CD in the drive. I have tried several different CDs that all worked in other computers and I have also tried to run a clean CD, but it still won read.
Below are some possible solutions to your problem:,
  1. Make sure the CD-ROM disc is an original disc, instead of a CD-R
  2. If the disc is original, check some more original discs to confirm that the problem is not from the discs.
  3. If it still doesn work, please contact your distributor or our branches abroad from whom you bought the CD-ROM drive.
   
2. There is noise when the CD-ROM drive rotates.
Since the rotating speed of current CD-ROM drives is very high, itís easy to have noise if there is label stuck on the discs. And sometimes the label might cause the breakage of discs.
   
3. Why can't the BIOS detect my BCD CD-ROM drive?
Start by checking the Operation of your System :
  1. Check if the DC power cord is connected to the power connector.
  2. Check the cable connection to be in right direction and must be secured.
  3. Check jumper settings at the rear side of your BCD CD-ROM drive to make sure there is no conflict with other peripheral devices. On an IDE cable, only one IDE device can be set `master` and the other one `slave`.
  4. Check your IDE settings in BIOS. The IDE port must be enabled to which your CD-ROM drive is connected.
   
4. How can I install my BCD CD-ROM driver into DOS?
For DOS:
Simply use the installation diskette attached with your BCD CD-ROM drive package. To install the driver you have to enter the command "install" after "A:>" prompt. It will install the driver for you automatically.
You also can install the driver manually as follows:

In Config.sys file add the line below:
DEVICE = C:\BTCCDROM\BTCCDROM.SYS /D:MSCD001 /V

In Autoexec.bat file add the line below:
C:\WINDOWS\COMMAND\MSCDEX.EXE /D:MSCD001 /V

You need to copy BTCCDROM.SYS file from your installation diskette to the folder you specified in Config.sys file. You also need to find where the MSCDEX.EXE located in your hard drive.

   
5. Why can't Windows find my BCD CD-ROM drive?
1. If your CD-ROM drive is connected to the IDE port on an IDE interface card (or a sound card), the card must be enabled first. If the IDE interface card (or a sound card) is not PnP supported, you need to install the driver for the card and make sure there is no I/O and IRQ conflict with any other peripheral devices. Also verify that the I/O address of the IDE interface card is the same as the one specified in config.sys. For doing this, please contact your card manufacturer for more information on how to configure interface properly.
  2. Very seldom errors might be caused by old 486 motherboards or the earlier ones. Try a different I/O speed value in CMOS setup. If the problem persists after you changed values, you have to install the CD-ROM driver under MS-DOS prompt.
  3. Your OS might be damaged for unknown reasons so that your OS could not recognize your CD-ROM drive. In this case, you might need to reinstall your OS to solve this problem.
  4. Please make sure you use the most updated Bus Master driver.
   
6. Can my BCD CD-ROM drive read a CD-RW disc?
1. Yes. BCD CD-ROM drives support Multi-Read and they can read CD-RW discs.
  2. There are two formats for CD-RW discs: "ISO9660" and "UDF". ISO9660 format of CD-RW discs can be read by the drive with no problem. UDF format of CD-RW discs can only be read after the "UDF 2.0 Reader" is installed into your computer. You can download "UDF Reader" at http://www.adaptec.com/support/files/udfreaders.html
   
7. My BCD CD-ROM drive can read an audio CD, but I hear no music when I play it, why?
1. Make sure the audio cable is connected from your BCD CD-ROM drive to the sound card CD-In connector. Check all speaker cables.
  2. Double click on "Master Volume" icon in system tray (on the right bottom corner of the screen) to adjust "Master Volume" and "CD/Line" adequately. Both "Master Volume" and "CD/Line" must be enabled.
   
8. My BCD CD-ROM drive is connected to the IDE port on the sound card and works fine under Windows 95/98, but when I enter DOS prompt the system can't recognize my CD-ROM drive, why?
Because Windows 95/98 has PnP function, Windows will enable the IDE port on the sound card automatically. You need to install the driver of the sound card to enable the IDE port in order to use it under DOS.
   
9. Why does my BCD CD-ROM drive read certain CD-ROM discs intermittently?
There is no manufacturer that will guarantee that their drive can read all media on the current market. It is possible that dust may cover Laser lens of a CD-ROM drive after long period of using. Dust affects reading accuracy of a drive. If it is the case, you can usually purchase an inexpensive CD-ROM drive cleaner from CD retailers. In addition, the CD-ROM disc is also an important factor. You may take look at the downside of the disc. If it is dirty, clean it with care.
   
10. Does my BCD CD-ROM drive support Digital Audio Extraction?
Yes. BCD CD-ROM drives support digital audio extraction.
   
11.
a. Why can't my BCD CD-ROM drive read certain CD-ROM discs, but others can read without problems?
b. Why does the system hang when particular CD-ROM discs are inserted?
This symptom is encountered frequently not only on BTC's drives but others also. Generally speaking, CD-ROM drives are sensitive and depend on the media (CD-ROM) quality significantly no matter what brand name the media is. Following are some of our major concern for your reference when you get stuck of this kind of troubles.
  1. CD-R / RW production quality (dye layer, reflection layer), if discs were not made well.
  2. CD-R / RW Recording / Rewriting quality (The laser beam strength of Recording / Rewriting), if the strength of laser beam was not stable during writing process.
  3. CD-R/RW storage quality (temperature, scratches, dust, fingerprints, etc.).., if there are too many scratches or too much direct sunlight on it.
It might cause the drive not being able to recognizes the media if any one of the factors above exists. That is why some drives but not all of they can read certain CD-R/RW discs.
   
12. The maximum speed of the CD-ROM drive is 52X. Why can't I get the performance as it is supposed to be?
The maximum speed 52X can be measured from outer ring of a CD-ROM disc only. The speed measured from inner ring is lower than the outer ring because most of high-speed CD-ROM drives on the market take CAV technology for stable reading ability. All BCD CD-ROM drives should reach the performance as we specified. If you can't get the maximum speed, it could be:
  1. Defective media (fingerprints, scratches or unbalance, )
  2. Data capacity is not large enough to obtain the necessary performance by a true CAV designed CD-ROM drive.
  3. If the testing programs you run are different from the ones from our test lab, testing results may vary.
  4. Your CD-ROM drive is defective.
   
  It can also be affected by the following factors:
  1. DMA (or UDMA) is not enabled in BIOS.
  2. DMA is not enabled in Windows 98. Please go to "Device Manager", check DMA function in the CD-ROM properties.
  3. The disc for testing is not an original one. Bad discs or duplicate ones might reduce the performance of a CD-ROM drive significantly.
   
13. How do I verify whether the CD-ROM drive is OK?
1. BIOS detection
a. If yes, that means all settings are OK (jumper, data cable and DC power).
b. If not, either the BCD CD-ROM drive is dead or the settings are wrong.
  2. Tray Eject/Close
a. If yes, your drive is powered.
b. If not, either the BCD CD-ROM drive is dead or the DC power is failed (or disconnected).
  3. Play audio CD by pressing the PLAY button on the front panel with headphone plugged in the headphone jack.
a. If you hear music, it means the circuit of your drive is OK.
b. If not, the drive may be dead.
c. If your drive is defective, please contact your dealer for help.
   
14. The disc running in CD-ROM drives cracked, why?
The current model of CD-ROM drives rotate with high-speed and using discs with cracks, scratched or of poor quality may cause damage to the CD-ROM drive and the data in the discs. Such discs may break during operation.
   
15. What do I do to evaluate the performance of my CD-ROM drive?
In general, the most common tool for performance test of CD-ROM is Nero CD Speed. It can test the function of transfer rate, CPU usage, and seek time and on the Nero website: http://www.cdspeed2000.com/
it free to download.
   
16. The CD-ROM drive makes noise while reading.
Yes. BCD CD-ROM drives support digital audio extraction.
   
17. The external speaker doesn't have sound when playing music CD.
1. Please check if the audio cable is connected to the audio connector properly.
  2. Check both rear side of the CD-RW drive and sound card on M/B (If Audio chipset is on board). If they are well connected, check if the sound card is working.
   
18. The tray cannot be ejected.
There are two possible reasons:
  1. Need to be ejected by the application.
Some of the burning or playing application will lock the drive. You have to eject by application and close it so as to restore the use of panel buttons.
  2. The CD is inserted incorrectly.
Please insert a paper clip or small rod into the emergency hole on the front panel for manual ejection.
