My dad had a blank hard drive on which I installed Ubuntu because it was easier than getting windows. Some WiFi drivers will not install. My dad only uses it for email, Craiglist, and chat on Facebook, so he doesn't care what OS he has as long as he can go online. I have the XP disk.
When I type sudo fdisk -l
in the terminal i get
/dev/sda1 * 2048 114300927 57149440 83 Linux
/dev/sda2 114302974 117229567 1463297 5 Extended
/dev/sda5 114302976 117229567 1463296 82 Linux swap / Solaris
Then i type sudo dd if=/dev/zero of=device bs=1M
and nothing happens. How do I wipe the whole hard drive?
