I installed pv so I could check progress of a usb installation, and I began the process with sudo dd if= | pv | of=/dev/sdb.
Well, it's supposed to ask me for my sudo password, but when I pressed Enter, it started showing progress before I could enter the password. I went ahead and attempted to type the password, but it was mixed in with the progress text. So, then I decided to do Ctrl+C to stop it.
My question is: Can I just do "sudo dd if=/dev/urandom of=/dev/sdb" to erase any data and start over? I JUST bought this drive today, so this is frustrating. I'm definitely not doing that again.
