[Does this log mean the disc is toast please?]

Thanks for the fast reply. For the files to have changed Agent would have had to be open and running, and I am 99% sure it was not. I'll try with a image file, and slow the burn rate down, as you suggest. Thank you!

[Does this log mean the disc is toast please?]

I am looking for disc burning software that works on win 7 64 bit, as my venerable nero 6 apparently will not. my first attempt to use imgBurn has me unsure if the write failed or not, as errors showed on the verification phase. I tried backing up my Forte Agent mail app and database.  I attach the log. Thanks!
