DRU-835A Firmware

Hi , I lost here , I have been searching Google the site all afternoon , trying to find some answers here , and Locate a firmware for this Drive.
I only bought a few months back , while it was fine to start ,
lately it’s been giving me errors during the testing, once the drive hits the second layer during testing it stop responding and the program can’t read .
the disk also does not work in any player .
the media I have been using is Verbatim MKM 001

The drive burns and reads fine with Memorex ritek D01
this drive was a replacment drive a liteon that did it’s job well 3-4 years.


Use nero cd dvd speed and perform a TRT scan.
