gundar: I'm sure the CGA is about returning it to where you bought it, but in my case, with hard drives, I have found the shipping to Asia, even at my expense, gets the replacement job done so quickly, it's worth the $25. When I have returned hard drives to stores and resell operations, the drives take months to be returned and are usually lost, misplaced or arrive somewhat partially tested/used.
In this/my case, $25 is money well spent. WD send the part back promptly at their expense if all paper work complies.
Not the answer you want, but perhaps a consideration for you to pay the money and remove some middlemen?
It's ok if you are happy to pay the postal costs but the point is that retailers do their best to avoid responsibilities under the CGA.
Because noone is going to take them to the disputes tribunal over a cost that is less than the filing fee they get away with it and the commerce commission is an absolute disgrace at enforcing this issue.
