Can you show full 'dmesg' output, including (a) everything from boot and (b) an attempt to burn a CD with cdrecord and (c) an attempt to burn a DVD with growisofs Full lspci would also be nice (I don't think the above is all of it, is it?) If you want to collect stupid amounts of [quite helpful] debug output, you may s/undef/define/ on the following lines of include/linux/libata.h in the kernel: #undef ATA_DEBUG /* debugging output */ #undef ATA_VERBOSE_DEBUG /* yet more debugging output */ If you are seeing error messages, this helps understand them: http://ata.wiki.kernel.org/index.php/Libata_error_messages Regards, Jeff
