Juz sam znalazlem odpowiedz na forum cdrinfo.com ale widzialem ze inne osoby tez o to pytaly wiec odpowiadam cytatem:
I know the web site says the LTR-40125W is Mt Rainier compatible, thats why I bought it, however I am now the proud owner of said drive & Nero Info Tool & WriteCDRW! told me it wasn't. Given that I had bought this drive on the understanding that it supported Mt Rainier writes I logged a problem report with LiteOn as clearly the drive does not function as advertised on their website.
LiteOn's response was (4th July) that the LTR-40125W does not support Mt Rainier at present but will with "one of the next firmware updates". I'm happy to wait a few weeks for this as I have found it to be an excellent drive for £50.
Tak więc Mt Rainier bedzie wspierany w jednej z kolejnych wersji oprogramowania
