it is the CD. or the drive take your pick. ive been burning cds for about 6 years now and i CONSTNANTLY see that problem. no matter what the cdr brand (from plextor to sony to matshita etc), to cdr media brand(tried about a dozen different brands). and ive tried about 6 different cd-r drives and in at least 3 different operating systems on probably a dozen different computers. it happens accross all of them. some more some less. especially on large files. and of course ive tried about 8 different cd-r programs. CDROMs just dont play well with CDR media. some of the older drives do (~8X ide) some drives are better then others but on the dozens of cdroms ive used all of them have the problem to some extent. CDR/CDRW drives have the best chances of reading a CDR/CDRW CD media. now on small files like MP3s i don't see it happen as often, mostly on large 100MB+ files(almost gauranteed if its 200MB+ on any drive). after all the variables i have changed my conclusion is that cdr media just doesn't work in some cdroms. maybe its the lasers in the drives themselves..maybe its the vibration/rpms ..who knows. i've just come to accept it and not use CDR for certain kinds of backup, or make smaller files. nate -- ::: ICQ: 75132336 http://www.aphroland.org/ http://www.linuxpowered.net/ [EMAIL PROTECTED]
