Too bad you are quite far from my area (you are in the North East, I believe), as of now have over 800GB free, so could have backed up some of your data....
^^ Hope you packed the drive in Anti Static material before packing it in anything else. You better call up WD on the tollfree number and inform them once you deliver the drive.
Finally my HDD reached their place yesterday, and today they sent be an email saying that they will send me a new HDD (model no WD7502AAEX-00Y9A0), the previous one was 500GB (model no WD5000AAKS-22V1A0)
