I wish I had read the comments on Smartware before I bought a 1TB WD Essential. The Smartware ran 10 hours and failed to back up the Others category. Even the backed up categories can not be retrieved. At the retrieve tab, there is 0 byte to retrieve. WD Tech Support supposed to answer questions within 24 hours, 48 hours later I am still waiting. Canada Computers charges 15% restocking fee. I guess I am stucked with this crapware (Smartware) from the drive.
