Hl-dt-st Dvdram Gsa-4167b

I recently bought a HL-DT-ST DVDRAM GSA-4167B LG Burnern it worked perfectly for a month. Now it reads the DVD & CD blanks occassionally only after I unstall and re-install the drive. then it might burn a couple of disks and goes back to sleep. Can someone tell me what is happening and if it possible to this problem.

“reading blanks” ?? Useless.
A burner only needs to recognize blanks to be able to burn to them…

Not recognizing blank media sounds like it’s the notorious PSU issue. You probably need to either update your PSU or try using the capacitor modification. (search the forum for details)
