severity 594753 grave found 594753 2.30.3-2 stop I think that I am seeing the same issue. I burnt a data CD with brasero which reported the operation as being successful. Some of the burnt file names were long and I asked brasero _not_ to keep a strict windows compatibility when it asked the question.
But some of the files are corrupted on the disc : their size is correctly reported (as per the original file) but they are empty or contains only zeros: $ ls -lh README -r--r--r-- 1 root root 10K 11 janv. 22:21 README $ cat README $ hexdump -C README 00000000 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| * 000027f0 All the faulty files have exactly the same content. And it appears to be the same when they are read on Windows XP (in an other computer, so with a different CD drive), even though there the file are shown as full of white space (with their correct size), but I did not check with an hexadecimal viewer, so this could just be a glitch of the viewer. The problematic files all have file names without extension (like "README"), but not all the file without extension are corrupted. In fact all the file without extension on the disc are corrupted except those whose names were "md5" (so i was able to discover the bug...). Also, when I try to read the faulty CD in my drive (the burner), the drive will sometime crash (with approximately 50% chance): I insert the CD in the drive, nothing happens in the computer (the CD is not mounted), except that I am seeing messages in kern.log similar to those of the bug reporter (I'm attaching some relevant part of kern.log). If I try something like manually mounting /dev/sr0 or trying to eject the CD, then the drive start making an awfull noise (I have never heard a CD drive makes such a noise so I can't describe it), but nothing else happens. The only way to return to a proper operation mode of the drive seems to restart the computer. Other CD (or the faulty one with half a chance) are working fine. I'm raising the severity to grave because this bug makes one believe that some files are properly backed-up while they are not, and could possibly lead to a data-loss. My CD drive/burner is an LG drive and is reported in dmesg as being a: ata3.00: ATAPI: HL-DT-ST DVDRAM GSA-H10N, JL10, max UDMA/33 I am running Debian Squeeze AMD64. I burnt the same data with an other burner on an other computer (but with the exact same Debian Squeeze), and the result was correct (no file corruption). I burnt the data three time on the problematic computer with always the same result. I burnt other files on CD to test the burner and all the burnt CD are correct, including some with file with no extension and with (on the sale CD) other file with very long filename causing brasero to disable (at my request) a strict windows capatibility of the disc. So my burner seems to work correctly (also, I never had any problems with it).
