Sorry this may be OT because the OP said to post only bad experiences. But since I already posted in this thread my uncertainties, here is a bit of news.
I created an RMA on Aug 19th (Thursday). I tried calling them but couldn't get anything but an engaged tone. So I sent off an email telling them I was unable to contact them on the toll free number. Same story Friday morning. I continued to try the phone but unsuccessful.
At 10:52 AM Friday I got a call from GATI saying they were coming home to pick up the parcel. I told them I was not at home so could they come the next day. They said they would call and come on Saturday.
Friday evening I got a call from home asking if I had called Bluedart to pick up something to courier. I said no but let me speak to the pick up guy. I told him I had not called but could it be Western Digital. He said Yes it could be because they do have some tieup with them. I told him I had received a call from GATI that morning for the same thing. He said WD has understandings with both of them. I told him I had to pack it and could only give it the next day. He said fine he would come the next evening.
Friday night I packed the drive and kept it ready and waited the whole of Saturday for either GATI or Bluedart to pickup. Nothing till 5 PM.
At about 5:30 PM someone came from Aramex and he had the correct reference of WD with him. He picked up the drive and it is being delivered to WD even as I write this.
So within a short span of time, I had 3 different pickups arranged by WD. Good treatment.
@techie_007 - Regarding the warranty, my original warranty was for 5 years i.e. till 2014. So when I get a HDD back through RMA, my warranty will still be till 2014 which is better than buying a new WD HDD today. That is what I meant.
