hibernation writes all the data from the ram to the disk and closes the
computer 100%
sleep puts the computer in a low powered state (how low depends on your
hardware) so it does still use some power to keep the data on the ram
chips...
sleep thus is faster to recover, because the data is still in the ram while
hibernation involves reading the data from the disk again and loading it
into ram.

You just format the drive , Clive
Get a New Mac , Jack
Y'don't need that crap toy, Roy
Just get yourself free
Boot from a *nix, Jix
You don't need to discuss much
Install XP, Lee
And get yourself free
