"So looks like the words 3 years warranty is bull shit."
- I don't think so. I bought a WD ext 3.5" 1TB hdd from all IT. Used it for a couple of days and it stopped working. I immediately called their toll free CS number. The CS asked for details like serial no and date of purchase and gave me another no to call. I did so and was asking about RMA procedures when this CS said that it may be just a problem with the power adaptor. (These techs should know. Maybe they had a particularly bad batch of power adaptors.) He asked for my address and 2-3 days later I received a courier package from Singapore. It was a new adaptor. I plugged it in switched it on and voila! the ext hdd works flawlessly. Thumbs up for WD customer support!

Is your 2.5" on ext power supply? Maybe its just the adaptor that died. Try suggesting that to the WD CS if you call them up. No harm if they let you try troubleshooting with a new adaptor.
