Hello Friends I bought a wd 1 tb external hard disk it is looking so good but some times its not working so good I am confuse that it is a hardware problem or wd all hard disk is waste of money. Some time it shows hard disk need format some time it is hanging problem some time its data shows nill no data in hard disk. packaging is so good but in packaging which is most important thing stuff is not good so I am not recommended to any one.
