Add this to your tool chest of better ways to hose yourself....
dd if=/dev/zero of=/dev/hda

The rm and fdisk commands are good for a quick and dirty shooting in the foot, but you can recover from them by relinking some inode pointers. I've run into my fair share of ooops moments with those commands myself.

But the king of kings, the point of no return is that nasty little dd command. Many admins, including myself, remove that command from our systems all together. I talked with an college admin that caught a little turd that thought he was cute to create a live cd that performed a dd on the lab disks. He ended up going to each computer in several labs and reordering the boot order in BIOS and locking the bios password to prevent booting from anything other than the hard drive.
