Hey guys. just got the BenQ Lightscribe DW1625 DVD writer and am having some problems with the installation! I poped it in a spare slot...and put in the power connection, and the CD-Rom cable dircetly from my old CD writer. I also have a DVD-Rom inside which i did not do anything to. For some reason, the PC doesnt recognise the DVD-ROM or the new DVD burner! i have this thingo when i open up my computer!

Notice no E: (my DVD-ROM)! What the heck is wrong? It works when i de-power the DVD-ROM!!!

my new DVD-RW is set on master, and my DVD-Rom is set to slave (as the CD-Rom used to be master)! its strange... :S

Also, currently i have just the DVD-RW powered up, and it burns DVD's, but wont burn CD's (even though it says it can, and i know it should)!!!

Thanks in advance!

Short summary: ’s BenQ DW1625 will burn DVDs but not CD‑Rs even after trying jumper/cable/Recording‑tab fixes (as noted by , and ). Because the usual physical/cable/jumper checks have been done, the next steps should focus on software/drivers, Windows I/O mode, and firmware/hardware isolation.

Practical diagnostic checklist (do each one, note results):

  • Try a different burning application (a lightweight tool and a full-suite) to rule out app-level engine problems; capture any error text/logs.
  • Inspect Windows Event Viewer (Application & System) immediately after a failed burn for driver or SCSI/IDE errors.
  • Device Manager: uninstall the optical drive entry (and then Scan for hardware changes) to force a clean redetect. Also check IDE ATA/ATAPI controllers → Primary/Secondary IDE Channel → Advanced Settings: Current Transfer Mode should be "DMA if available" rather than PIO. If stuck in PIO, uninstall the IDE channel and reboot.
  • Remove any packet-writing or legacy ASPI layers (InCD/DirectCD/old Adaptec ASPI) which commonly interfere with CD writes.

A common Windows fix (backup first): export the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class{4D36E965-E325-11CE-BFC1-08002BE10318}, then remove values named UpperFilters and LowerFilters if present, and reboot. This clears bad filter drivers that block CD‑writing; always export before editing.

If software/driver fixes don’t work: check for an official BenQ firmware update (follow vendor instructions carefully), and test the drive in a known-good machine or under a different OS. If the drive still reads/writes DVD but never writes CD across platforms, the CD laser/calibration path is likely faulty and RMA/replacement is warranted.

Did you set the jumpers...
One should be set to master and the other set to slave...

yeah...i have played with the jumpers, and tried every combo (sorry for not mentioning in the topic)...this is why im really confused!

hey, right click the drive, go to the RECORDING tab, and click "Enable CD recording on this drive"... or something to that effect, my PD NEC DVD RW did the same thing and i couldnt explain it, so i went back to basics, and what'ya know, it worked, hope this helps for you and hope you enjoy your lightscribe

thanks mate, i went to the recording tab and it was already ticked! i changes around the cable and it recognises it, but it still wont burn CD's!!!

Your current status is that your drive works in every respect except that it cannot burn CD-Rs?

Member Avatar for goldeagle2005

For the problem about both Optical drives not working, i guess its a jumper conflict. If not, try replacing the data cable. Also, you might try using both your new and old drives on another computer to eliminate the problem....

As for your second problem, is the CD you're trying to write on of a good quality? Some recorders don't recognize a bad quality disk.
