I am using a brand new iMac 3.5 ghz core i7 running MacOS 10.9.5 to which I have attached an LG BP06LU10 blue-ray reader/writer.
I have just tried to copy an ordinary DVD disc with some home video on it to another disc DVD-R using Toast 10 Disc Copy . It reads, then ejects, the disk okay. However when insert a blank DVD-R it writes the Lead IN track but the quits with the error above.
I have searched the internet but, although there are people with a very similar problem, mine seems to be unique in that everyone else seems to get error 5 (-5?), whereas I get error -32030.
I have tried 'Repairing Permissions' and using both USB plugs to power the LG External burner. On my other iMac the LG works fine with just one its two USB plugs inserted into the back of the computer.
Another thing I have noticed is that, when this failure occurs, Toast 10's "Read From:" option under Disk Copy changes to read "FireWire CD-ROM" instead of my LG Drive. Furthermore my LG Drive is no longer an option. This means that I have to quit Toast 10 in order to eject my blank DVD.
I also notice that my blank DVDs appear to have been rendered unusable.
