i just bought an oem version of this burner, and when i installed it, i encountered this problem.
-can’t read dvdr’s most of the time. normally the led goes blinking for a long time, then dies soon afterwards. When this happens, everytime i click on that drive it asks for a cd or it looks like i have a blank inserted.
-on rare occasions that i get the drive to burn a dvd, i’m having trouble reading em. Like, i can’t launch the files from the disc i inserted, and when i copy it i get a crc error.
i’m beginning to think that the drive i got is defective, as one of the dvdr’s that i inserted got two hole marks (the size of the lens) since i tried various firmwares to no avail
