I'm not a technical person, so please bear with me. I don't know if my problems are hardware-related, software-related, media-related, all of the above, or other.
I've got a Plextor 708UF, Nero 22.214.171.124. Running XP, SP1, if that matters.
I have sporadic problems burning both CDs and DVDs. I've tried various brands of media, probably none of them top grade. At the moment I'm using HP DVD-R and TDK CDs.
Sometimes the burn goes smoothly, sometimes I get an error message in Nero telling me that "Data verification failed." Whether I get that message or not, I always use the Nero Toolkit ScanDisk file test and surface scan.
If a disk fails the test, I pitch it and burn the files to a new disk. Sometimes it takes three tries to get a good one.
But today I noticed something weird -- I ran ScanDisk from a different drive (I have a CD reader in this PC in addition to the 708UF), and it failed. It showed a lot (over 13%) of damaged areas. But when I ran ScanDisk on the same CD in the 708UF drive, it passed the tests with no errors.
Why would it pass the test on the burner that created it, but fail on another CD drive?
Does this mean I shouldn't trust ScanDisk? Is there another scan utility that's better?
And are the damaged areas most likely to be caused by software problems, hardware problems, or the media?
BTW, I do shut down all applications -- including virus scanners -- when I burn a disk.
I've been burning CDs for many years without any problems at all, even using bargain-basement media. I was using a Plextor SCSI CD burner, and would even burn CDs while running other programs, and had a success rate of probably 99%. I can't get the Plextor SCSI CD burner to work in this PC (which I just got last year), which is one reason I bought the 708UF.
Anyway, I would appreciate any suggestions for troubleshooting the burning problems, including recommendations for the best way to confirm that a burned CD or DVD has no errors.
