i have another problem as i have nero8 now and it always data verification fails at 0% and says several sectors are not readable (always burn them at 8x).after stopping it and reinserting it in the same recorder (LITE-ON) ,it reports it as blank but in LG combo i can extract the files without any read error.so why data verification fails.

and some multi session disk DVD+R reports themselves as DVD+RW and Book type DVD-ROM.not able write again on the same disk.

Startup imgburn, insert the DL, post the info from the imgburn disk window.


#3

IMGBurn show
LBA : 0

Error: No Reference Position Found
unknown
device not ready(no reference position found)

and i already posted info of the DVD by Kprobe ,it also says
020600 no reference position found ,unknown disc type.

Probably some off the wall media. Try a good media that is supported by your drive.


#5

why does kprobe shows the the same info(i.e. DVD-DL) when it encounters unreadable disk even if it is DVR+R or DVD-RW.i have used several brands like moser baer ,writex (MCC code before was mitsubishi and noe moser baer) and this "national " DVD+DL.but SONY disk run OK.so i will stick to sony disk.even Sony 16X DVD+R runs at 18X on Liteon.

Use smartburn and see what it says…


#7

i have burned an image file on the same DL disk using my friend’s LG DVD Writer.it recognises it with no problem. but still it runs on his drive even after burning.my both drives liteon DVD writer and LG combo not able to read this disk.here is smartburn info from his PC.
