Thank you for your reply, even if currently not
that interesting for me because after the first
CD writer for IDE were available I stopped to
use SCSI and didn't come back to it since then.
Does the Python open() command not work the
same way for SCSI drives as for IDE or USB
drives (I can't try it myself, because of above)?
P.S. for those who are interested I have uploaded a
Python script I wrote for myself to have a reference to
this subject to:
