Flashing My Laptop's Dvd-rom Firmware

ok, I’ve got this problem you see, and I hope someone can help me…
According to nero burner’s info tool, my laptop cd/dvd-rom drive ( qsi dvd-rom sdr-081 version 5.0.2195.1 ) supports reading dvd-r’s . But after burning some on my external dvd writer and trying to read them on my laptop nothing happens. And it acts like theres no disc in the drive.

I’ve searched the net for newer drivers , or means to flash the firmware hoping this will solve the problem…but I can’t find a place to do this.

Can anyone help me?

thnx in advance
