Query: Warning for both product and manufacturer!!!

My hard drive crashed after 5 months and only a handful of uses due to a USB power surge. I've learned later that the power adapter is pretty much needed even though they don't tell you that. Anyway, in addition to the crash, Western Digital refused to replace my hard drive. They said the warranty expired because it was sold to Amazon (who I purchased it from) over a year ago. After my explanation and faxing in of the receipt they still didn't accept my warranty. It was also horrible to get through to support. I will definitely not buy Western Digital products again. LaCie here I come!!!
