I brought WD My Passport Ultra 2TB external HD to expand the storage capacity of my Windows 8 computer. Well, it was working quite fine in the start but all of a sudden my external hard drive stopped working I take it to a local IT store where then resolved this particular problem. However, after two or three month I heard clicking noises from my external drive I consult to my friend and they suggest it is a symptom of corruption and yes it get corrupted soon. Apart from this I often experience several issues while using this very external drive on my computer. Sometimes it even stop recognizing my computer as well. Its so annoying and performance is very low.
