Further to my previous post…
I tried doing formatting with UDF1.5 (Physical format was checked) of Ritek Excellent DVD-RAM CPRM media in Optiarc DVD RW AD 7170A. It gave an error after 39 minutes.
I immidiately tried formatting it with UDF1.5 (physical format unchecked). The formatting was successful. I am able copy any content into the media.
Any explanations for this ?
