I checked the screws and the case and everything is tight. Both noises are the drive "whining". I do have a CD burner but no other DVD burner. Basically the Benq makes the same noise as the CD burner plus adds the same whine you can hear from a Hard disk drive. Maybe because it spins so faxt (my CD burner is an 8X only).
Also the green light on the front in always on (even when not reading) - is this abnormal?.
I bought the retail package because I was hoping for some meaningfull documentation but there is nothing usefull (next time I'll order the OEM).
Thanks for the help.
