Actually, I tried that, but either it's smarter than I am or stupider than
it pretends to be :-P :-). The ioctl() would always succeed (even with no CD
in the drive), and always returned the same 804 bytes. Furthermore, the
first 400 or so bytes of said data were all 0, followed by what might have
been useful information or might have been junk. Maybe it just doesn't work
with ATAPI drives...
