Finally I replaced my Hitachi/LG GSA-T50N with a Samsung SN-S083B drive. The bezel is compatible so it sums up to removing two screws and paying EUR 28,00.
After the drive installation I upgraded its firmware to the newest version (SB01) that can be downloaded from http://www.samsungodd.com/. The drive works perfectly and passes all tests that the Hitachi/LG model failed. It is disappointing that Asus Germany is unwilling to recognize the severity of this problem. A simple download could have fixed this issue faster and cheaper. I also find it strange that the drive manufacturer Hitachi/LG does not offer any support for its drive although it is obviously not working correctly. -- Asus M50VM-DVD doesn't mount and can not be ejected https://bugs.launchpad.net/bugs/289261 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
