Q1. Combo cannot be recognized.
(1) The drive might not be 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 are connected with one IDE cable, the jumper has to separate one to MASTER & the other to SLAVE.
(3) If Windows can't detect combo, click on the "Add New Hardware" in the Control Panel. Windows will start detecting.

Q2. Do I need to install driver for this Combo Drive?
No, because Windows 95/98/98Se/ME/2000/XP have IDE driver built in and you don't have to install another driver.

Q3. The drive can read data and audio discs, but it can't read DVD discs. Why?
Because Windows Operating System doesn't support the playback of DVD discs and you have to install another software to play DVD discs. (e.g.: Power DVD or Win DVD)

Q4. My 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 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.

Q5. The drive can't 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.

Q6. There is noise while reading.
If the disc is eccentric or there are labels stuck on the disc surface, it will cause noise.

Q7. The drive doesn't have power.
Please check if the power cord is connected securely.

Q8. 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 the 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.

Q9. The drive cannot read some general discs.
Please check if the disc has deep scratches, fingerprints, or other contaminants on the surface. Clean the disc if it's necessary.

Q10. The drive cannot write.
We suggest as follows:
(1) Use the burning software which is provided by original supplier and bundled with combo or download the updated 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 packet writing software.

Q11. "Buffer underrun" always occurs while writing discs.
Here are some suggestions:
(1) Close the screen saver & TSR (Terminate and Stay Resident).
(2) Quit other redundant application while 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.

Q12. Does this drive support over-burning?
Yes, but please use burning software which supports this function.

Q13. Does this drive support CD-Text & SAO (Session At Once) function?
Yes, it does support CD-Text & SAO function and you may edit the title or content into your music CD.
