Thanks mciahel and JoeC00ll
Yes the drive is attached to the add on card (Sil680). I have the hard drive hooked up to the onboard IDE channel. Don't want to put the hard drive onto the card as I will haveto reformat. When I was originally testing the burner because of the problems with the add on card, I had it set as slave to the hard drive, which of course it didnt like. I sufferred with power calibration errors, key hardware errors etc and couldnt get a completed burn from it. The drive wouldnt even erase a -RW, and read burnt discs as blank.
Since I managed to get the ide card flashed to non raid bios and drivers (thanks to the help of these forums), the burner 'appears' to be working, giving successful burns but not all are readable, or completed.
I did try the burner in an older machine and it burnt data ok, movie backups....nope.
I would be really peeved if the Verbatims were bad, as they weren't very cheap. But you never know. I did also try Imation (CMC) and no names which DVD Identifier picked up as MMC (which I used to use before trying the Verbatims to fix the other problems) also.
I will upgrade Nero CD-DVD Speed and test again with the suggestion. To be honest as I have been successfully burning for a couple of years now, it didnt even occur to me to keep up to date with any info on forums. But for the last month I have been reading non stop.
Thanks again, I will try a new scan and post.
I am also thinking of getting an IDE Sata adapter board for the hard drive (like the Abit Serillel 2 , to free up the onboard IDE controller. Any feed back on these?
