Just a query then...
I have just checked on the dual layer DVDs that worked the last time i wanted to back up this amount. There is no label on them whatsoever.
I have read other people's DL problems & did note the verbatim comment, but i dismissed this simply because i have used other DVD's before, that are unbranded and work.
I use unbranded CD's all the time & they always work. I use unbranded single layer DVD's that work all the time no problem. The last set of dual layer DVD's i worked were unbranded and worked.
the DL DVD's i'm using at the moment that are failing, have "Datawrite" on them. I have used CD's & DVD's with this on the label & they've always worked.
So why should THESE dl dvd's i'm using not work?
Also, why would the firmware be an issue when the firmware that is currently installed is the same firmware that was installed the last time that dl burning worked for me?
I'm not for a minute saying you're wrong. I just do not understand why, what worked last time, is what you're saying could possibly be the reason it is no longer working.
To me that doesn't make sense. I'd just like to understand before i go down this route.
