Movies is an external USB drive. I tabbed some of the above in an effort to make it more readable. The problem has never manifested itself on Movies, / or /home. And only one did I have a problem with my 128GB USB stick, not inserted into a USB port at the time I ran the above. The optical drive (/dev/sr0, Bluray r/w) was also empty. It is the optical drive that is driving me crazy. Last night was the first time I had the (unreachable) message at the command line, which it continued to display regardless of which drive I was on at the time. When the (unreachable) message was displayed the ls command failed, even if I was on /home or /. But I probably caused the (unreachable) message because it appeared right after I issued a umount -l command. At the time I was trying to get rid of a mount point folder that had been created when I inserted the previous DVD. I could not delete it ("device is busy"), nor could I umount it; that is why I used the -l option. _______________________________________________ PLUG mailing list PLUG@lists.pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug
