Sony made a zip file available when I registered the drive. But due to a crash or 8, I’ve lost it. I’ve had no response from Sony to a query I made 3 months ago. So I’m hoping someone has this zip file saved somewhere. I’ve saved some mixed files as Data files but no longer can access them, I get “windows cannot read…using a format not compatible”. I’ve installed UDF 2.5 on my XP Pro sp3 system but no luck. I believe I need to install the zip file to read these discs.
