I could use WD portable hardware for only 3 months. I still don't know what happened to my hardisk. For first 3 months it was working smoothly without any problems. After that it started becomming too slow and whenever I connect my hardrive my pc started hanging.
Suddenly one day it stopped working such that my pc doesn't recognise the hardware. Firstly I thought the problem is with my pc and I have connected my hardware to my friends pc also but nothing changed.
I lose almost all of my important files due to this. I went to many service shops still I could't get it repaired.I would suggest this a waste of money
