First, are you having problems with erasing any CD-RW discs, or just those formatted with DirectCD?
According to Nero's helpfiles, "SCSI Target Error" may appear if a disc has already been inserted before Nero asks for it. So call up Nero| Recorder| EraseReWritable, choose Full-erase and an erase speed not greater than your media rating, then click Erase and insert the disc when Nero asks for it.
What does Nero InfoTool say about Autorun for your burner? And the ASPI layers?
You should try both settings for Autorun: on and off.
To get Autorun off, either use Notepad to create a file called autorun0.reg that contains the following four lines
and run it by double clicking on autorun0.reg in Explorer, or edit the registry. (If you replace the final 0 by 1, you'll get Autorun on.)
Also check that none of your programs is "hiding CD-R media", etc.
Finally, you may try SuperBlank from
