The device /dev/sr0 is typically the first CD/DVD device found by the operating system (and /dev/sr1 would be the second). All it's saying (loosely) is that the device wasn't cleanly closed before eject and an inode is still being "accessed" even if no available any longer by some process. This is why you can't mount anything new at this point with the device still being "busy", according to the kernel. dafr _______________________________________________ PLUG mailing list PLUG@lists.pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug
