Fwd: No supported write modes with LG GSA-H62N SATA DVD+RW
I'd mentioned that I'd forward the exchange that I accidentally took off-list yesterday for the benefit of anyone following along or coming by later and finding this in the archives. I won't bother sending them all, just two that seem to have the most relevant information.

The difference between Linux & Win32 is definitely below the cdrecord code.
I have one question: Did you run this with administrator privileges?
In Windows? Yes, the account I log in as has admin privileges.
Could could try to prepend ASPI: vs. SPTI: to the dev= parameter
to verify whether this was ASPI or SPTI?
Sure thing. It seems less happy now:
$ ./cdrecord.exe -v speed=1 -audio dev=ASPI:2,0,0 tmp/*.wav
./cdrecord: No write mode specified.
./cdrecord: Asuming -sao mode.
./cdrecord: If your drive does not accept -sao, try -tao.
./cdrecord: Future versions of cdrecord may have different drive dependent defaults.

Can not load ASPI driver! ./cdrecord: No such file or directory. Cannot open oruse SCSI driver.
./cdrecord: For possible targets try 'cdrecord -scanbus'. Make sure you are root.
./cdrecord: For possible transport specifiers try 'cdrecord dev=help'.
But everything is fine if I pre-pend SPTI: or leave the dev= option bare, as in my previous test. Does that tell you anything useful?
Unless the win32 drivers modify the SCSI commands as a workaround, the problem
must be inside the linux kernel.
If the related Linux drivers are developed in a professional environment, then
the developer should have a logic analyzer that allows to snoop at SATA level
and should be able to fetch the drive you have.
