In case you have data that you really want to recover, sometimes putting it in a frezzer for 24 hours, then plugin it in about 20 minutes after you take it out might make it work. (Just make sure you do 2 things: First, dont put it inside your case, drag the cable outside. This is to avoid condensation to create a drop of water in your case. Second if you really need the data, take it to someone who can recover it for a price, since after the frezzer trick, the drive will be even less likely to be recoverable).
In other words, do it only if you "kinda want" whats on it.
