Hmm you are the second to report that, but I also have reports that
says it works. Maybe we are facing different firmaware versions...
However I cannot reproduce the problem on any of my drives (but
I dont have access to a 8100), so I'm not sure what to do about
it. There was a change in atapi-cd.c at a time that changes the
problem, it doesn't fix it, it just moves it somewhere else, and
that change does break other devices...
Hmm, I guess I'll have to try to locate a 8100 somewhere and
try to find out what it doesn't like...
