Died after the first two weeks.It does not died completely. Motherboard can find the drive, but sometimes cannot recognize. Sometimes every thing looks good, but when read a disc, it fails. I was thinking it is because of the disc, but after tried some more discs and tried them in another machine, I am sure it is because of the drive.When try to write a disc, it keep telling the disc is not writable, please enter a empty disc...
