My LG hl-dt-st rw/dvd gcc 4480B will not detect blank dvd-r’s when i put them into the tray what could be the problem?
Welcome to cdfreaks.
This is a CDRW/DVD combo, thus not being able burning DVD’s.
Not sure how LG drives work, but IIRC my old Pioneer combo made the same. Couldn’t even check disc MID in it before drive spitted the disc out again.
Here’s a link for more info on your drive. Link
A combo is not suited for recognizing blank dvds.
