I am new to this forum but I recently bought an LG GSA-4160B Burner that is a refurb. I have he drive set up as master and it reads a DVD and CD just fine. I Inserted a blank IMation DVD+R and tried to burn using Nero 7 the burn went fine untill time to finalize the disk then I get a PMA Update Failure. I tried a different brand JVC DVD+R and then the same thing happens. Next was an IMation DVD+RW and everything went great and the DVD played in my DVD player but to my suprise I placed the RW disk back in the 4160b and it couldn’t read the disk. I next tried to burn on a Sony DVD-R and the drive would not recognize the disk at all. I did a firmware update to the newest version and still the same problems. I then went to burn a music CD to see if it might just be my version of Nero and it finalized just fine. Then I tried a different burning program called DVD Power Burner and yet no disk but a DVD+RW can be read in my DVD player. Also on top of that any disk that has been burned from other burners this drive will not read or recognize. Then I tried to go back to the olded firmware version on the LG website and still all problems are there. I called LG to ask them and they never heard of the PMA Update Failure and will not give me any support on this drive since it is a refurb. I really don’t wanna be out of the money spent on this drive and I would hope that I got more than a drive that can only read DVD movies and burn CD’s. The seller of this drive will not provide a refund just a drive upgrade for a fee that I don’t wanna pay and it is looking like I am stuck with this drive. If there is anyone here that can help please do so and thank you in advance.
Also I did get 3 disk to finalize and work in my DVD player out of like 60 disks 1 from the IMation and 2 of the JVC; using the DVD Power Burner which does not give the PMA update failure.
