What's the best way to destroy a 2.5" SATA drive (going on 4 years old if that makes any difference) before disposing of it to undoubtedly prevent any possibility of data recovery? Should I just smash it with a sledgehammer until it's in bits and pieces? That seems simpler and more effective than drilling holes in it.
I assume that running a disk wipe utility on it beforehand is unnecessary/pointless, right?
Once destroyed, can I just throw it away (is it safe and legal given the materials?), or should it be recycled somehow (and if so, how)? Recycling may be difficult if it has been smashed into pieces...
