that's formatting to ntfs or fat 32. when you pick the full option all it does is add checkdisc to the format.
when you delete a drive, you have 2 options. a high or low level format. one write on top of everything and your data is really still there (high level format, which is quick). the other write zero to your drive and get rid of your data (low level format, which is slooooowww). your data can still be recovered with advance tools, though.
companies like maxtor (powermax) and western digital use a hybrid approach now (this is the best way). they write zero to the firsts and last part of the hard drive and quickly wipe the rest. this is particularly useful for getting rid of bootsector viruses, something the xp cd or fdisc can't do. this is also a good wipe of the hard drive, that doesn't take forever to do
