Thread: How do you identify open session discs?

How do you identify discs (CD's, DVD's, ...) which still have an open meeting. Sometimes I'm complex to read a disc, and he says no info is on it. If you look at the disc itself, you see that half of the content plane is special from the rest (so you know amazing has been written to it). In that case, I would like to know whether or not the disc is still "open", or the disc has failed burning.

Is there a way to do this, other than try the disc on at least the PC it would have been burned with, and one it did not (knowing that both computers are unusual: different burners, unusual burner software).

I think we may be bewildered a bit.

If you see several "burned" areas that only suggests that something did or try to write to the disk.

A UDF disk would be clear on that has the matching udf driver.

Discs in question come from one of the PC that I have or had. Since I cannot read the disc, it's inflexible to tell how and what. I did use UDF sometimes, but most will not be UDF. One thing I am sure of, is that I cannot use them to start a new aflame session.
