NEC AD-7173A & Verbatim DVD+RW Formating Problems



Hello everybody, i am a new guy in this forum and i find it exciting, great Job!

Recently i got an AD-7173A Nec/Optiarc and have no problems burning media.
Until now, when a friend of mine, gave me a package of Verbatim DVD+RW (4x Certified!).
I try to write data even in ISO mode or UDF but nothing, still getting messages, “formating disc failed”. I also tried Erasing The ReWriteable But I get an error message “Invalid Command”!

My Firmware Version is : 1-01 official
Nero Version:
Region 2

thx in advance


Try to format them using Imgburn and DVDInfopro.
Fast or complete/full mode.
