    I've used Nero CD Speed's CD Quality Test feature on a few recently burned cd-r's (Kodak & TDK). The results i got showed 1000-3000 errors (occured close to the end of the cd, after testing 85% of it).

    Is this number of errors high/low/normal ?

    Can someone suggest me other methods of testing the quality of a cd-r (before or after burning) ?

    Thanks

    Im burning at x6 speed on my Teac CD-R56S. This is also the drive i tested the media's on and got those results.

    However, if i test them on another drive (Teac CD-540E reader), the Kodak media has 0 errors and the TDK media has 167 errors.

    any idea?

    I'm not familiar with this burner (the CD-R56S) and a quick search of the Teac site revealed nothing.... how old is the burner? I would imagine the newer CD-540E has error correction stuff included.

    Its a pretty old burner, over 4 years old.

    Is more than 1000 errors considered really bad?
    because some times i get much more than that.

    (Im talking about the testing called 'CD Quality Test' in Nero CD Speed..)

    I'd imagine so - Unless my version of CD Speed is horrendously out of date, it only reports C2 errors.

    And I'd say 1 C2 error on a recently burned disc is a bad sign.

    I suggest using CD Doctor - although I dont know if your drive reports C1 errors or not.

    You can tell the quality of the CDR before you burn by searching this forum :)

    Another weird thing is that tested a 3 year old burnt Kodak gold cd, and it showed ~30,000 errors.. but i could read all the data from it to hdd, and it was ok..

    Alternatively, CD Speed could be reporting errors that aren't there, or your drive is pretty innacurate with C2 errors.

    Rumours are: CD Speed will be reporting C1 errors in the distant future.

    And yes, CD's will work with a myriad of C2 errors on them, but it doesnt bode well for the life of the thing.

    --C1 Errors = Not a prob is small - medium doses

    --C2 Errors = On the way out, probably - copy data somewhere else

    --Unreadable = Pretty self explanatory

    This is a very old drive you are using. Could be be that your drive is wearing out? Errors on the outer parts of the CD could suggest balancing/vibration problems, or similar.
