OK, I have a bit more info, I managed to burn the CD on another box and when I tried to mount it using this drive, it gave me in the logs May 26 02:41:59 ccs.covici.com kernel: end_request: I/O error, dev sr0, sector 942680 May 26 02:41:59 ccs.covici.com kernel: Buffer I/O error on device sr0, logical block 117835 May 26 02:42:00 ccs.covici.com kernel: end_request: I/O error, dev sr0, sector 942680 May 26 02:42:00 ccs.covici.com kernel: Buffer I/O error on device sr0, logical block 117835 but it did mount successfully! and I did a diff against the same iso mounted via -o loop and there were no differences. -- Your life is like a penny.
