I *just* have wasted two of my blank CD in like fifteen minutes ago, I keep wondering if I created the ISO files in the wrong way or was it burncd's fault.. Until now here.. I get like this: ===================================== # burncd -f /dev/acd0 -e -s 6 data NT2004.iso fixate next writeable LBA 0 writing from file NT2004.iso size 662576 KB written this track 410656 KB (61%) total 410656 KB only wrote 4096 of 32768 bytes: Unknown error: 0 fixating CD, please wait.. ===================================== I tried the another ISO and I get the same thing by stopped at 32768 bytes. I am going to use cdrecord for now, hope it will work ok.
