Hello all,
First of all, let me introduce myself a little bit. I am the responsable
for the development of the Nero Linux burning application. So I have
access to all the source code of the application.
Now let's go with the story: It seems that there is a slight problem in
the libata (and also the new pata_xxx) interfaces with the data returned
by the INQUIRY cmd since every S-ATA or IDE device is assumed to be a
SCSI dev.
Normally, the IDE devices (physical type) can be differentied with the
format field of the inquiry data, i.e. the last bytes (ANSI version) are
set to 0 -> This is done and works great with USB external devices for
example.
The thing is that with S-ATA/IDE devices when using the libata/pata
driver, the version field is (always?) set to 5, as any _real_ SCSI
device, and thus the physical device type cannot be checked anymore.
I cannot go so deep in details, but our burn engine is differentiating
IDE and read-good-old-SCSI devices and handles them sometimes in a
different way, so this differenciation is really important for us.
-> How can I detect the real physical device type now?
Best Regards,
Mathieu
