Hi
I have a idvd16dd, which I use as a external using a USB case. I have used it successfully to write DVD's from this drive on DVD-R, DVD+R,

DVD-RW.
Just recently (without any firmware upgrade. using Version: A091 ), it started to fail on writing on any DVD media I have. I was successful in

only 1 writes on a DVD-R, out of my last 20+ attempts. I like to use RW media but NERO will stop recognizing the drive itself when I insert a

RW media. I have posted a log below - I compiled the whole thing and just before pressing BURN, I inserted the below listed RW media.

Now while using this drive as external, I have a case, which I also swap to use for a 200gb internal hard drive. while reconnecting the dvd

writer, I make sure all connections are tight.

I also tried to update Firmware to A190- but still the same problem
