### Subject: dvdisaster harms my system
Let us firstly see what a patched dvdisaster does.
Patched means here, that the quick hack below has been applied.

All works fine. cd1.ecc has been created from cd1.iso, /dev/hugo-ist-doof has
been ignored.
On the other hand, if Script invokes the original dvdisaster binary, regardless
of its
release, the things change. I tried 0.70.6 ... 0.72~rc1-1. dvdisaster hangs for
a long time
before it starts to work as expected. During the hang-time one can continue his
work.
The hanging process cannot be eliminated.

This software tries to kill me.
One can imagine what would happen if the TEAC burner would be attached
to the first SCSI controller, where the system disk lives.
My ideas.
I do not expect that anyone cleans up the SCSI code such that my TEAC burner
works,
but I expect that this TEAC burner is not touched without a good reason.
The latter means
1) with --create and --ecc <regular-file>, probing in /dev/ should not happen.
2) if a device is given via --device, probing in /dev/ should also not happen.
The quick hack I usually apply to make dvdisaster working for me looks as
follows.
It should be noted the the Windows version of dvdisaster works perfectly, even
on a full-SCSI system.
