My Book Essentials 1TB
Walmart offerred me a 1 year warranty for $5.98. When I registered the product online, it was already out of warranty on the 18th of this month. The NC start with WCAV. All Western Digital products start with WD. ?? The packaging states "1 Year limited warranty". I copied all of the included software to a local folder, then formated to NTFS with Windows 7.
