Запись DVD+RW
 

Помогите решить такую проблему.
Не получаеться записывать DVD+RW, хотя DVD-RW пишуться на ура. Пишу таким макаром:

growisofs -dvd-compat -Z /dev/cd0 -jcharset "koi8-u" -output-charset "cp1251" -V "My CD" -D -J -r -l -v /data/ftp/pub/new/cd

Результат такой:
Executing 'mkisofs -jcharset koi8-u -output-charset cp1251 -V My CD -D -J -r -l -v /data/ftp/pub/new/cd | builtin_dd of=/dev/pass0 obs=32k seek=0'
mkisofs 2.01 (amd64-unknown-freebsd6.2)

Заранее благодарен за ответы.

Даная проблема решилась заменой привода по гарантии.
