I bought the 4040B before christmas. At the time the current firmware was 301 I think. I had a hard time finding media for it (dvd-r) that would burn at 4x. Eventually I did though. I bought a spindle of RitekG04 disks. DVD Identifier reports that the 4040b should be able to burn it at 4x.
I used Nero and Movie factory to burn about 4 or 5 disks at 4x and it worked beautifully. Then on the 6th disk a strange thing happened. As soon as nero finished the leadin the drive would start making a 'clunking' noise, like the head resetting itself or something. Nero would lockup and the drive would keep clunking until I powered down my system. After rebooting the disk would still be blank. This same disk would burn at 2x with no trouble.
I figured it had broken, so after a lengthy rma battle in which LG said the drive was fine, I forced them to replace it. I have just installed the new drive, updated the firmware to 302 and it does THE SAME EXACT THING. If I try to burn 4x it clunks away. If I try to simulate 4x it errors immeidiately saying 'No seek found' or something. But it will burn at 2x.
I'm at the end of my rope trying to figure this out. Any help would be greatly appreciated!
