I have purchased one of the Optodisc DVD+RW (OP470), formatted it using Nero's InCD and using less than 10 times on my Optorite DD0203 drive. 2 days back, the drive suddenly took more than 5 minutes to detect the disc, after which it was unable to recognize the UDF contents on the disc, only the non-UDF portion.
I tried erasing the disc in Nero, but the disc was ejected in less than 5 seconds and format failed (both quick and long format). Luckily I was able to retrieve the UDF contents of the disc using CDRoller.
I think this could be a manufacturing defect, first of all there are no dirt and scratches on the disc, as I was very careful with it, and secondly my drive still works with my Verbatim DVD+RWs.
Does anyone have problems with DVD+RW media, in particular Optodisc? How can I force a format using some tool so that the disc can be made usable again?
