I have a HL-DT-ST DVD-RW GCA-4080N burner in my Compaq R4000 laptop under XP SP2 (basic specs below). With all the media I have burnt recently the drive seems to run more slowly than it should, it is supposed to be 8x speed but it takes about 15 mins to record a full 4.38GB image.
I've tried burning in Nero and Alcohol 120%. Nero simply reports 8x writing but takes 15mins to do it. Alcohol gives a "Illegal speed 8.0X (11080 KB/Sec) for this medium" error at the start of recording. I've tried a number of 8x and 16x +R and -R media recently and have had the same trouble with all. (The full media info from Alcohol is given below for my 16x -R Verbatim media.)
The write speed graph for Alcohol is given below, it shows a step shape as the drive speed steps up from 2x to 4, 6 and then 8 towards the very end. I'm sure the drive used to burn much faster than this when I first got it. Is the problem just my newer media? I believe I have the latest firmware, mine is 0C35. Is there anything I can do to resolve the problem?
I've attached the log from alcohol 120% along with the speed graph, the drive info and disc info. Here they are:
