1. What are the DAO, SAO and TAO writing modes?
1. DAO (Disc-AT-Once): With Disc-At-Once writing mode, the CD-Recorder laser will not stop until the whole disc recording is finished. In this writing mode, the disc will be closed and there are no link blocks between any two tracks.
  2. SAO (Session-AT-Once): With Session-At-Once writing mode, the CD-Recorder laser does not stop until all data from the current session is written to disc. Session-At-Once is related to the process of recording multisession discs.
  3. TAO (Track-AT-Once): With Track-At-Once writing mode, the CD-Recorder will record one track at a time. In between every track, the CD-Recorder laser stops while the hard disk prepares the contents of the next track.
   
2. Does my CD-RW need any device driver under Windows 95/98/Me/2000/XP platform?
Actually there is no need to install any driver if you're using Windows platform since Windows has its own default driver. The following steps will assist you to get your drive to work :
  1. BIOS detection: That means all settings are OK (jumper, data cable and DC power).
  2. Sometimes Windows 95/98/ME/2000/XP might not detect your drive, then you can use "Add New Hardware" to add the CD-RW on your system. ("Start/Settings/Control Panel/Add New Hardware/ to add new hardware". Then reboot your PC).
  The default driver only supports reading function under Windows 95/98/ME/2000/XP. To achieve writing, please install burning software. (NTI CD Maker, Easy CD Creator, Nero Burning ROM tc.)
   
3. The burning speed of CD-RW drive is too slow and the burning fails often, why?
Start by checking the Operation of your System :
  1. Maybe the OS is unstable or too many application programs are running at the same time. Close other unnecessary application programs.
  2. If it still doesn work by quitting other applications, it possible that the OS is damaged for unknown reasons. If so, you might need to reinstall the OS to solve this problem.
  3. Check if "DMA" mode on Windows is enabled.. If not, enable the mode.
**Under On Windows 98 / ME:
Go to "Start / Settings / Control Panel / System / Device Manager / CDROM / Settings / DMA".
**On Windows 2000 / XP:
Go to "Start / Settings / Control Panel / System / Device Manager / IDE ATA-ATAPI Controllers / Primary or Secondary IDE Channel / Advanced Settings / Transfer Mode / DMA if available".
   
4. When should I use the DOS driver?
You only need the DOS driver when you want to use your CD-RW drive under DOS environment. If that's the case, the driver is included in the diskette named "Device Driver Installation Diskette" in the package that came with your CD-RW drive. Please note that this is only necessary for DOS and Windows 3.1..
If your operating systems is Windows 95, 98, or NT, the CD-RW drive can be auto-detected by the system and extra drivers are not necessary. Please remove the redundant DOS driver if it is installed.
   
5. What OS platforms are compatible with my BTC CD-RW drive?
A BTC CD-RW drive is compatible with Windows 95/98/NT/ME/2000/XP and it can read and write under Windows 95/98/NT/ME/2000/XP.
Under DOS, the drive can read CDs only.
   
6. Which IDE port should I connect the; hard disk drive, BTC CD-ROM drive and BTC CD-RW drive to?
You may consider one of the two ways recommended below to connect your drives.

To get the most stable performance for the CD-RW drive to write:
  • Primary IDE Master: Hard Disk

  • Primary IDE Slave: CD-ROM Drive

  • Secondary IDE Master: CD-RW drive


  • For best hard disk performance:
  • Primary IDE Master: Hard Disk

  • Secondary IDE Master: CD-ROM drive

  • Secondary IDE Salve: CD-RW drive
   
7. Is it important to use a high quality CD-R/RW media for recording?
Yes. The quality of CD-R/RW media varies from different brands. A CD-R/RW media with bad quality causes writing error and makes a CD-ROM drive difficult to read.
   
8. My BTC CD-RW drive was working perfectly, but it failed to write data onto a CD-R/RW recently. What happened?
Most likely, some things have been changed in your system, either software or hardware.
Please see below:
  1. If you installed an anti-virus program recently as a TSR (terminate-and-stay-resident program), you could corrupt the CD-R/RW to which you are writing. A TSR anti-virus program is the No.1 killer because it checks every file written onto the disc. This interruption may last long enough to cause a buffer underrun.
  2. Disable some programs (such as TSRs, terminate-and-stay-resident programs).
  3. Disable your screen saver.
  4. Disable power-management feature.
  5. Defragment your hard drives at least once a week.
  6. Disable e-mail, FAX, modem.
  7. Try a different brand of CD-R/RW.
  8. There are conflicts with old device drivers. Remark out any 16-bit (real mode) device drivers in your CONFIG.SYS file in Windows95/98/NT.
 

9.

Your OS or pre-mastering software has been damaged for some reasons. Please reinstall it.
 

10.

Hardware inside your computer is unstable, e.g., check the fan of the CPU to make sure it is not covered by dust, which would cause the CPU overheated.
  11. After a long period of use, the laser lens inside the CD-RW drive may covered by dust. Clean it with a lens tissue or soft cloth carefully.
   
9. How can I duplicate an audio CD?
Start by checking the Operation of your System :
  1. Always remember not to violate the copyright before duplicating an audio CD.
  2. Make sure you are in an appropriate operating systems environment to make the duplication.
   
  • use a CD-ROM drive that has jitter correction controlled by a firmware, such as BTC's CD-ROM drives.

  •  
  • Under Window 95/98/ME/2000/XP, close all other applications.
   
10. I created audio CDs with my BTC CD-RW drive, but it can not be played back by my home CD player. Why?
1. A home CD player can not play the disc if more than one session is written on the disc, i.e. a multi-session CD.
  2. A CD player can not play the disc of single session if the session is not `closed` when writing.
  3. Your CD player might skip the disc due to bad CD-R quality.
   
11. Why does my burner always show "Illegal Request" or "Invalid Block Address"?
Please do not run other applications when burning the disc to reduce the error occurrence.
   
12. What is SD2 format?
SD2 (Safe Disc 2 protected CD):
On CDs protected with "Normal" Safe Disc, you have an area of about 10000 sectors where there are always unreadable sectors followed by some readable and so on. This grouping changes from CD to CD and it's typical Safe Disc fingerprint that is checked by the protection-code inside the executable. This fingerprint can simply be re-produced by writing the image in RAW mode. Safe Disc 2 now also has such an area but also some groups of so-called "weak" sectors. Why are they called "weak"? Well, it seems that these sectors can read without problems from the original CD, but when trying to read them again from a copy, they suddenly seem to be damaged and sometimes can only be read with the second or third attempt - and sometimes not at all! The burned weak sectors can only be read in the burner itself or not at all.
   
13. What is the definition of "Session" and "Multi Session"?
1. Session: Session refers to the data written to a CD during the span of a single recording. It is an area on the disc that consists of a Lead-In Area, a Program Area and a Lead-out Area.
  2. Multi Session: Multi Session refers to a form of recording that allows data to be written over more than one session. The disc can be removed from the recorder in between sessions and then replaced.
   
14. Sometimes it takes longer to burn at high speed than with longer speed? Why? Is this a CD-RW drive problem?
Actually, different factors may cause this situation. First, if the quality of original discs is poor, the RW drives on the current market have Burn-proof function, when the transfer rate of CD-ROM drives is slower than CD-RW drive and the burning might fail, the Burn-proof function will start up and wait. That is why it takes much longer.
   
15. BTC CD-RW drive cannot be recognized.
1. It is possible the drive hasn been connected properly. Please check whether the IDE cable and power connector are tightly connected.
  2. Check if there is jumper conflict. Normally, if 2 drives connected with one IDE cable, the jumper has to separate one to MASTER & the other to SLAVE.
  3. If Windows can't detect BTC CD-RW drive, click on the "Add New Hardware" in the Control Panel. Windows will start detecting.
   
16. BTC CD-RW drive doesn't have power.
Please check if the power cord is connected securely.
   
17. The CD-RW drive cannot read some general discs.
Please check if the disc has deep scratches, fingerprints, or other contaminants on the discs surface. Clean the disc if it is necessary.
   
18. The drive can read former session(s) of the CD-R disc, which has been written twice or more times.
Before writing CD-R discs with data copy, remember to choose "Import session" so as to read the former sessions.
   
19. The CD-RW drive cannot write.
We suggest as follows :
  1. use the burning software which is provided by original supplier and bundled with this CD-RW drive or download the update file from internet.
  2. More capacity of hard disk is needed if using hard disk as temporary buffer.
  3. Place the disc correctly.
  4. The blank disc needs full format first if using Packing Writing software.
   

20.

"Buffer underrun" always occurs while writing discs.
Here are some suggestions :
  1. Close the screen saver & TSR (Terminate and Stay Resident).
  2. Quit redundant applications when burning.
  3. Select good quality and high-speed supported blank discs.
  4. Increase main memory capacity.
  5. Select other burning software.
  6. De-fragment the hard disk.
  7. Keep the source & destination discs clean. (no scratches, fingerprints or contamination.)
  8. Copy data as image file to hard drive to avoid buffer underrun.
  9. Keep the system clean. Do not install redundant driver or application to reduce system loading as well as confliction.
  10. Enable Buffer Underrun Protection mode if your software supports it.
