More Sony DW-U18a drive problems

Hey I just joined the forum and read some of the other posts on this specific drive but my problem seems to be a little different. I have this Sony DW-U18a installed and it has no problem recognizing CD’s, CD-r’s, CD-RW’s and DVD’s but for some reason when i insert blank DVD-/+R’s it acts as though nothing is inside the drive. I have downloaded the latest firmware for it UYS4 and patched it with Omnipatch but continue to get the same results. Any help would be appreciated.

It won’t recognize a blank unless you are in a burning program. If i put a blank disc in my LiteON burners they do nothing unless i’m in the process of burning something in Nero, ImageBurn, DVD Decrypter etc.
