GSA-H42N & Imation DVD-RAM: strange no-go

Last week I bought the LG GSA-H42N :slight_smile: .
A couple of days ago, I got an Imation DVD-RAM (double-sided, 9.4GB, type 4), just to play around with this ‘new’ (for me) standard :slight_smile: .
Yesterday, while trying to re-format the DVD-RAM with UDF 2.0, that operation could not be completed by the DVD-RAM utility :doh: .
Since then, no reformatting is possible on the side of disc I was playing on :a .
The only error message I could get is from DVD Decrypter (I used this one to verify if the disc could be seen): ‘Medium format corrupted’ :sad: . The process of reformatting sometimes doesn’t even start; sometimes it starts (needing physical format), but after 45 mins stops claiming about generic errors :confused: . On the surface of the disc there is an inner circle darker than outer (you know, the difference between areas with data and areas without), and absolutely no scratches. I tried the drive on 2 different computers, used InCD instead of the DVD-RAM utility from Panasonic: all no-go’s.
Any hint out there? :o
Thanks in advance!
PS: please note that the other side of disc is fully functional!

Try it in safe mode and/or ditch Nero InCD.

Tried it on the second computer & drive sitting in an USB enclosure: still no-go :a

What’s the MID on the RAM disc? If it’s not Panasonic or Maxell, you might just write it off as being a bad disc.

You could try using the Panny RAM driver to do a full physical format. Also double check with the WPTool that it is not write-protected.

Hi i’ve got a similar problem with the LG and Imation disk. The DVD-RAM writing takes ages. 1GB gets copied in 16hrs on Fat32. I’m guessing the drive doesn’t like this make of DVD-RAMs.

Thanks for your answer.
Here is the MID:
