New question #76243 on gnome-terminal in ubuntu:
https://answers.launchpad.net/ubuntu/+source/gnome-terminal/+question/76243

I am trying, within a Hardy live CD session, to wipe clean a hard drive to enable reinstallation (don't ask...). Wipe utility dban aborted suspecting bad sectors. I turned to badblocks for diagnosis. My first attempt to launch it (sudo badblocks /dev/sda)  led to a line about the device seeming to be in use; I went to the filesystem to see about unmounting but nothing showed as mounted. But on second attempt, badblocks started scanning. 

It was going fine, though using a lot of CPU, until I tried simultaneously to launch a Google search. This overloaded the machine and screen greyed. I left it for ages to work through its backlog but after more than an hour, still unable to get any response, powered off. Now in a new session, my first launch yielded "command not found" and after I did "sudo fdisk -l" successfully and retried "sudo badblocks /dev/sda" it simply moves the cursor to the next line without any output.
