I've tried reading any FAQs and manuals I could find, but I haven't been
able to figure out why my drive isn't working properly.
Synopsis: It burns CDs reporting no errors, but when I try to look at the
CDs, the operating system (either Linux or WinNT) won't read the disk.
I know the drive works for reading. Everything is being done under linux.
I'm appending the terminal session of burning a cd and the running sformat
on it.
Thanks,
R.
