Аз също съм имал проблем с подобна записвачка (LG 52х24х52 / SuSE 9.1 
kernel 2.6.5 / k3b). Не съм следял грешки, защото я използвах 
инцидентно. Като цяло работеше нормално като изключим това че менеше 
скороста на записа по време на запис (независимо дали е фиксирана или 
не). След извесно време започна да дава грешки при запис на високи 
скорости, а после и на ниски. В момента мисля че изобщо не може да 
записва а чете също доста трудно ( това се случи за период от 6 месеца). 
Като цяло съм останал с впечатление че проблема е хардуерен. Пробвал съм 
TEAC CDRW на същата машина със същите настройки и работеше чудесно.
С поздрав,
Михаил Борисов
