wnaspi and DVD Burner

[Stefan Leichter]

Hello,

i tried to make some progress with Ahead Nero, but now i'm stuck. I found the 
NeroSDK-1.08.zip and inside the comand line tool NeroAPITest.exe. The source 
code of NeroAPITest.exe is in the archive too. This makes finding the 
problems easier.

Executing the comand 'wine NeroAPITest.exe --listdrives' the open function in 
SCSI_OpenDevice fails first with ENOMEDIUM. Putting a disk into the drive the 
command fails with errno 30 (Read-only). Opening the drive read only works, 
but next is a write on the file descriptor that fails because it was opened  
readonly ...

The scenario above fails only for my PATA DVD burner. My SCSI DVD reader and 
my SCSI CD reader are working well with the command sequence listed above.

My OS is Debian etch (32bit) the burner is a Plextor PX-716A.

Is the reason for this the difference between IDE and SCSI in the kernel?
Is it a fault of the DVD burner device (firmware)?
What might be a workaround for the problem?

Thanks for your thought

Stefan
