GSA 4040b trouble

Hi, I hope someone can help here, my GSA4040b was working perfectly until yesterday I went to use it and it would not recognize any sort of dvd, it will recognize cd’s but not anything to do with a dvd. I have tried this unit in two other machines with the same result. Also when I insert a dvd I hear a clicking sound coming from the drive, however it does not make the sound with cd’s. Lastly in the device manager it appears as two things, 1st-"Generic DVD-ROM SCSI CdRom Device, 2nd-“HL-DL-ST DVDRAM GSA-4040B”. I have tried getting rid of the first one but to no avail. I have also tried to reflash the firmware. I’m running out of ideas and getting ready to throw it. Any other help would be appreciated. Thx

I have exactly the same problem if any one could help me . Please do it .
